Pepper Spray - Can you bring pepper spray on a plane?

Can you bring pepper spray on a plane? If so, can you take it in your checked baggage or carry-on luggage? This is a question that many people have when they are traveling.

The answer depends on the airline and how much pepper spray you want to bring. In this article, we will go over ways to travel with pepper spray, as well as some airlines that allow it for either carry-on or checked bags.

One four-ounce container of mace or pepper spray can be brought onto a plane in checked baggage, according to the TSA. But, it has to have a safety lock that prevents spilling. Pepper spray containing more than 2% tear gas is not allowed on checked baggage or carry-ons.

Check with your airline’s website before you bring pepper spray on a plane. The restrictions may vary depending on the airline.

Can you fly with pepper spray in your carry-on?

No, you cannot carry pepper spray on a plane. It’s best to leave your pepper spray home. You might be thinking: what if I am carrying the pepper spray for self-defense? That’s fine, but the TSA can’t take your word for it. Pepper spray can be used as a weapon too.

A high-profile organization like the TSA can’t take any risks when it comes to bringing potential weapons on planes.

Four ounces of pepper spray can be brought in your checked baggage, but it must contain 2% tear gas or less. Many travelers don’t know that they can’t carry pepper spray on board, and they have to leave it behind.

When the TSA confiscates pepper spray, travelers have a few options.

1) Give the pepper spray to the TSA agents.

2) Return the pepper spray to your car.

3) Give it to someone who is not traveling.

4) Put it in your checked baggage.

Note: In some states, it’s illegal to carry pepper spray under certain conditions. Do some research beforehand to make sure that you are traveling to a state where it’s allowed.

If pepper spray is accidentally sprayed on a commercial plane, this can be dangerous for passengers and may lead to an emergency landing in some cases.

Pepper Spray Travel Size

People Boarding Plane

According to the TSA, you can pack one four ounce (118 ml) container of pepper spray in your checked baggage.

Can you take pepper spray abroad?

For international travel, one four ounce container of pepper spray is allowed in checked baggage. International travel follows the same TSA guidelines as travel within the USA. Pepper spray is not allowed in carry on bags under any circumstances.

Is it illegal to carry pepper spray?

You can carry pepper spray in all 50 states and Washington D.C. But many states have restrictions, which include the following:

  • Age (must be at least 18 years old)
  • The concentration of pepper spray
  • Size of the container
  • Criminal history – convicted felons cannot carry pepper spray

Pepper spray laws vary by state, and you can check out a complete breakdown of the regulations at this link.

What self defense weapons can you bring on a plane?

Here is a list of the most common self-defense weapons and their TSA rules and regulations.

1) Bear spray – not allowed on the plane or in checked baggage. Most animal repellents have more than 2% concentration of tear gas, which the TSA prohibits in checked baggage and on the plane.

2) Black jacks (self defense weapons) – not allowed on the plane, but allowed in checked baggage

3) Body armor – allowed on the plane and in checked baggage

4) Brass knuckles – cannot be carried on the plane, but can be brought in checked luggage

5) Pocket knife – not allowed on the plane, but allowed in carry-on luggage. Sharp objects are typically not allowed on the plane for the passengers’ safety.

6) Stun guns, tasers, and other shocking devices – not allowed on the plane. You can bring them on checked baggage, but they must not have lithium batteries. Stun guns also must be secured so that they can’t be accidentally turned on en route to your destination.

7) Swiss army knife – not allowed on the plane, permitted in checked baggage

8) Tear gas – not allowed on the plane or in checked baggage

Can you bring pepper spray on a plane? Looking at the Major Airlines

Inside of crowded plane

In visiting each airline’s website, none of the major airlines allow pepper spray or other similar sprays on their planes.

Concerning checked baggage, none of the websites appear to mention TSA’s specific regulation which allows one four-ounce container in your checked luggage.

So, it might be best to call the airline beforehand to clarify. But here’s a quick summary of the pepper spray regulations for the major airlines.

Can you bring pepper spray on a plane American Airlines?

American Airlines does not allow mace, tear gas, or pepper spray in checked bags or carry-on bags. One four-ounce container is allowed in checked baggage per TSA’s guidelines.

Can you bring pepper spray on a Southwest Airlines plane?

Southwest Airlines does not allow self-defense sprays of any kind on flights.

Can you bring pepper spray on a United plane?

United Airlines does not allow mace, pepper spray, or tear gas on a plane or in checked baggage. One four-ounce container is allowed in checked baggage per TSA’s guidelines.

Can you bring pepper spray on a Delta plane?

Mace, pepper spray, bear spray, or tear gas are not allowed on a Delta plane at any time. One four-ounce container is allowed in checked baggage per TSA’s guidelines.

Can you take pepper spray on an Alaska Airlines plane?

Alaska Airlines allows a single four-ounce container of pepper spray in your checked baggage, according to the TSA’s regulations. Like the other airlines, pepper spray, mace, or other self-defense sprays are never allowed on a plane.

Can you take pepper spray on a plane to Mexico?

Traveling with pepper spray depends on the airline’s regulations, not where you are traveling.

Generally, airlines do not allow pepper spray in carry-on luggage since it can be used as a weapon. But most airlines allow them in checked baggage.

Be sure to check on the airline’s website to make sure you can travel with pepper spray.

Once you get to your destination, the question is: is it legal to carry pepper spray? In Mexico, carrying pepper spray is legal if you’re 18 and not a convicted felon.

In America, some states restrict the use of pepper spray depending on the container’s size, concentration, the person’s age, and criminal history.

Does mace explode on a plane?

Pepper spray, mace, and other self-defense sprays will not spontaneously explode under normal conditions.

If a fire starts in the airplane cabin, the extreme heat may cause the mace to explode. Mace could also explode if it is punctured with a large object. But the chances of mace exploding on a plane are incredibly low.

How to Travel with Pepper Spray

Inside of plane at night time

Airlines across the board do not allow pepper spray in carry-on baggage. The TSA allows one four-ounce container in checked baggage, but not all airlines allow pepper spray in checked baggage.

Here are a few things you can do before traveling with pepper spray to make your experience smooth.

  • Double-check pepper spray requirements on your airline’s website.
  • Keep pepper spray out of your carry-on luggage or your pockets while going through airport security. The TSA will confiscate it or ask you to put it in your checked baggage.
  • Make sure that it’s legal to carry pepper spray where you are traveling. You don’t want to get to your destination and then realize that you aren’t allowed to carry your pepper spray. Convicted felons and people under 18 years of age are not allowed to carry pepper spray in several states.
  • Make sure that your pepper spray contains less than 2% of tear gas. This is the maximum amount of tear gas allowed in checked baggage according to the TSA.

Do planes have speed limits?

Do planes have speed limits?

Swiss plane taking off

Under certain conditions, planes have speed limits.

  1. All aircraft must remain under 250 knots (288 miles per hour) while below 10,000 feet.
  2. At or above 2,500 feet, the conditions change a little. If you are at or above 2,500 feet and within four nautical miles of an airport with Class C or D planes, you cannot fly more than 200 knots (230 miles per hour).
  3. If the aircraft’s minimum speed is greater than 200 or 250 knots, the aircraft can run at that minimum speed without penalty.
  4. Noone can fly a plane over a Class B airport or fly in a VFR corridor in Class B airspace at a speed of 200 knots (230 miles per hour) or more. A VFR corridor is an area where planes can fly without communication with air traffic control.
  5. When commercial planes taxi between gates and runways, they must be at a max speed of 20 knots (23 miles per hour) and 10 to 15 miles per hour on turns.

Above 10,000 feet, there are no speed limits or regulations. Most commercial planes fly at a cruising altitude of about 35,000 feet, so they are not subject to a speed limit. However, they cannot simply go as fast as they want. Pilots must abide by the maximum safe speed outlined by the aircraft manufacturer.

Further, to remain fuel efficient, planes should ideally stay at their cruising speed. Cruising speed is approximately 500 to 550 miles per hour for most commercial aircraft. Jets tend to be faster and can have cruising speeds up to about 650 miles per hour.

On today’s aircraft, some pilots follow a cost index which tells them how fast to go to maintain maximum fuel-efficiency. Staying fuel-efficient is better for the environment and it allows airlines to charge their passengers reasonable fares, among other benefits. Learn more here.

Do private jets have speed limits?

Jet plane - Do planes have speed limits?

Above 10,000 feet, private jets don’t have any speed limit. Below 10,000 feet, all aircraft, including jets, must stay below 250 knots or 288 miles per hour.

The main benefit of private jets is that you can get to your destination faster than flying commercial. Private jets’ cruising speed is around 600 to 650 miles per hour, 50 to 100 miles faster than commercial aircraft.

Do helicopters have speed limits?


The vast majority of helicopters can achieve a maximum speed of about 250 miles per hour due to their design and the behavior of propellers. There are only two helicopters that have achieved higher speeds, the Sikorsky X2 and Eurocopter X3. These planes flew at 299 miles per hour and 293 miles per hour respectively.

Explaining helicopter speed limits gets a little complicated, but check out the video below if you’d like to learn more. Then keep reading for a quick explanation of why helicopters can’t eclipse the 300 mph mark.

Let’s walk through how a plane moves, step by step.

For a plane to rise, its lift must be greater than the weight of the helicopter.

Once it reaches cruising altitude, it can hover when lift equals the weight of the helicopter.

Then the next step for the helicopter is to go forward, which requires some amount of forward thrust.

To do this, the rotor disc must be angled forward or downward. Then some of that lift will be translated to thrust and the plane will move forward.

The rotor disc is a combination of a plane’s blades and parts that help it to move forward. Some planes have two rotors, and some have a tail rotor as well.

But, looking at a plane’s blades from above, there is a problem. Let’s say the blades are moving counterclockwise. This means that the top half of the blades are moving in the direction of travel, while the bottom half are moving away from the direction of travel.

But blades generate lift based on how fast they rotate through the air. Now you might see the problem.

The area of the blades that is moving with the direction of travel will generate more lift, while the area that is moving away, or “retreating,” wants to hold the plane back. It’s not generating as much lift.

This phenomenon is called “retreating blade stall.” The retreating blade moves slower and therefore generates less lift than the forward blade. The steeper the angle of the plane (known as the angle of attack), the more lift the forward blade will generate, and the less lift the retreating blade will generate. This limits the maximum speed a helicopter can go.

Helicopters can help compensate for retreating blade stall thanks to the rotor, which allows them to increase their angle of attack as the blade rotates. 

So, as the helicopter increases its speed, the forward blade lowers its angle of attack and the retreating blade increases the angle of attack. This helps balance out the amount of lift that the blades generate, allowing the helicopter to go faster.

However, the angle of attack can only be increased for so long. Eventually, it reaches a point where flow separation occurs. At this point, the helicopter produces less lift. So, it no longer can increase its speed.

To eliminate this problem entirely, planes can have two blades, one that provides lift in one direction, and one that provides lift in the opposite direction. The next limit or barrier for planes is the speed of sound, but we’ll get to that in another article.

Hopefully this quick explanation helped you understand how helicopter speed limits work. If you would like a little more information, check out the above video.

What are the fastest helicopters?

  1. Eurocopter X3 – 293 MPH (2013)
  2. Sikorsky X2 – 288 MPH (2010)
  3. Westland Lynx – 249 MPH (1986)

The Westland Lynx was truly ahead of its time, as its speed record would take over 30 years to break. Eventually two military helicopters in the early 2000s, the Eurocopter X3 and Sikorsky X2, broke the Lynx’s record.

What is the slowest speed a plane can fly?

Planes must move at a speed where enough air passes over the wings to generate lift. To stay in the air, commercial planes need to fly at between 150 and 180 miles per hour.  This speed is called stall speed.

Technically, vertical takeoff and landing aircraft (VTOL), such as helicopters, can fly at 0 miles per hour. This is called hovering.

Planes lined up on a runway

Can airplanes get speeding tickets?

Strictly speaking, no. There are not “tickets” for flying like you might get when you drive your car too fast or get in a wreck.

Pilots can receive violations for breaking federal aviation regulations (FARs).  For example, all aircraft must remain under 250 knots under 10,000 feet. Also, pilots can get a violation if they exceed the maximum safe speed according to the plane’s manufacturer.

In addition, pilots could get in trouble if they disobey air traffic control. But this isn’t black and white. They are allowed to throw some regulations out the window and fly faster than normal in the event of an emergency.

Man Holding Bluetooth Speaker

There can be a lot of confusion when it comes to traveling with Bluetooth speakers. Is that even allowed? What are the rules and regulations for bringing one on board? What is the best Bluetooth speaker for travel?

We’ll go over these questions and more so you can make an informed decision about taking your speaker on the plane!

The TSA allows passengers to bring Bluetooth speakers on a plane. You can bring your Bluetooth speaker in your checked luggage or carry-on bag. If your speaker uses a Lithium ion battery, do not pack it in your checked bag. They have a small possibility of catching fire while inside the aircraft. If you’d like, you can remove the batteries from your device and take them with you on the plane.

Most airlines will allow you to use your Bluetooth speakers on a plane. But, you can’t use them during takeoff or landing.

Can you take a portable speaker in your hand luggage?

Yes, you can take a portable speaker in your hand luggage. In fact, we recommend taking your speaker in your carry-on because you can keep close track of it.

After take-off, you can use your speaker if you’d like. But this is not the best etiquette on a plane with other passengers. You’d probably be told to turn it off or turn it down.

Can I bring a JBL speaker on a plane?

Yes, you can bring a JBL speaker on a plane. When you get to airport security, take the speaker out of your luggage and set it into the bin for screening. Do not use your JBL speaker on the plane during takeoff or landing.

Some airlines have different policies when it comes to using Bluetooth speakers. If you’re in doubt, ask the flight attendant about the regulations. Or, before flying, check the airline’s website.

Bluetooth Speaker Buyer’s Guide

Cylindrical Bluetooth Speaker - JBL

There are seven things to consider before buying your Bluetooth speaker. They include the sound quality, microphone, size of the speaker, battery life, waterproofing, price, and style.

Sound Quality

What are you using your Bluetooth speaker for? If it’s to listen to music or podcasts on a long trip then the sound quality is important.

A good rule of thumb is if you can’t tell what song is playing after listening for a few seconds then the speaker probably isn’t worth it. If the speaker sounds muffled, the quality isn’t too great, either.

Look for a bass radiator and 8-12 Watt drivers to get the best sounding Bluetooth headphones. Some speakers even have dual drivers for twice the power!


Does the Bluetooth speaker have a microphone? This is important if you are using your wireless speaker for hands-free phone calls or Skype video conferences while on the go.

If you’re an avid traveler, find a Bluetooth speaker with a microphone to make chatting on the go convenient.

Size of Speaker

Do you want to pack light and small when traveling, or do you need something that’s a little bit bigger?

Compared to large speakers, most small speakers won’t have great sound quality. But they are much easier to travel with. You can even find some at a pound or less that can fit in your pocket!

Battery Life 

Before you head out on your road trip, make sure your Bluetooth speaker is fully charged! You can find speakers on the market that last anywhere from six hours to 24+ hours! If you’re going on a long trip, look for one with high battery life so you don’t have to worry about keeping it charged.

But if you’re just using it around the house, you won’t need to worry as much about battery life. Just plug it into an outlet and let it charge every night before you go to bed.


Do you want to spend a lot of money on your Bluetooth speakers, or would you prefer to buy something a little more budget-friendly?

Most bluetooth speakers range between $15 and $300. More expensive speakers will have a longer battery life, better sound quality, waterproofing, and long-range Bluetooth connection. They’ll also be a little more durable than a low-end speaker.

To decide how much you need to spend, think about how often you use your speaker. If you use it daily, it’s probably worth it to spend a couple of hundred dollars more for a higher-quality Bluetooth speaker. But if you don’t use it very often, think about getting a lower-priced Bluetooth speaker.

Also, if you’re getting the speaker for a trip, think about where you’re going and how long you’ll be gone. You might want to take your Bluetooth speaker through the city, in the mountains, on the beach…pretty much everywhere you go.

If that’s the case, look for a more durable speaker that’s lightweight but still has that sound quality you love. Yes, this may be more pricey, but it’ll be worth it.

Waterproof and Dustproof

To find a speaker that will last you years, make sure it is waterproof and dustproof. This will keep your speaker in good condition, even if you take it outdoors or enjoy the beach during the summertime.

Even if you’re not going to be around water with your speaker, it can save you money if you accidentally get the speaker wet!

Most Bluetooth speakers are IPX-5 to IPX-7 water resistant. IPX-5 means they can be used in the shower or around the pool, but don’t submerge them in water at all. IPX-7 speakers are more water-resistant than IPX-5s. These speakers can be partially submerged with no damage.


Bluetooth speakers come in many different shapes and sizes, including rectangular, circular and cylindrical. Pick what style you like best, or what style is easiest to transport for you!

Bluetooth speakers also come in a wide variety of colors so pick one that suits you.

That wraps up our buyer’s guide and travel guide on bluetooth speakers.

Remember, you can bring your bluetooth speaker in your carry-on or checked luggage. But, if it has lithium batteries, remove them and take them in your carry-on.

Also, you can use a bluetooth speaker on a plane, but not during takeoff or landing. However, a plane might not be the best environment to blast your favorite tunes. Instead, put on a pair of headphones so you don’t bother others.

Before you get everything packed up for your trip, make sure you can bring it on the plane! Check out our articles below to learn more.

Do planes fly at maximum speed?

Do planes fly at maximum speed?

Plane Flying in Sunset - Do planes fly at maximum speed?

Do planes fly at maximum speed? This is a question that many travelers have asked themselves. While it may seem like a simple yes or no question, there’s a little more to it.

We’ll discuss six reasons why planes don’t fly at their maximum speed below.

  • Cruising speed is more efficient
  • Maximum speed puts too much strain on the plane’s structure; it’s unsafe
  • The main benefit outweighs the cost. Max speed would cost the airline significantly more than the benefit they get from reducing the duration of the flight
  • Airfare rates would skyrocket
  • Drag increases exponentially as planes approach Mach 1, which cripples fuel-efficiency
  • Planes need to follow what’s called a “cost index” to remain the most efficient

6 Reasons Why Planes Do Not Fly at Maximum Speed

In general, commercial planes do not fly at their maximum speed. They are designed to cruise at a speed of about 500-550 miles per hour. The max speed of most commercial aircraft is only slightly higher at about 600 to 650 mph.

Commercial planes do not fly at maximum speed to save money on fuel and stay in great condition. If planes flew at max speed all the time, they’re risking serious damage to the engines and structure. Airlines definitely want to avoid buying a new passenger plane or jet, if possible.

At cruising speed, planes fly at about 35,000 feet. The higher planes fly, the thinner the air. Therefore, the faster they can fly. So planes fly high to reach their cruising speed. They can afford to fly for a long time without losing a lot of money because of the thinner air.

The thicker the air, the more wind resistance. So if a plane doesn’t reach cruising altitude, its fuel efficiency will decrease.

Lufthansa Plane

Most commercial planes aim for what’s called long-range cruise speed, or LRC. It’s defined in the context of maximum range cruise speed, or MRC.

MRC is the speed that a plane should go that is the most fuel-efficient. LRC is the speed above MRC that results in a 1% decrease in fuel mileage. This 1% decrease results in a 3-5% speed increase, which is a good payoff.

Even though airlines are paying a little more, the time they save getting to their destination makes the 1% decrease worth it.

What’s the exact speed you can get the 1% decrease in fuel efficiency? Well, it depends on the aircraft and requires some complex calculations done by mathematicians.

What we do know, though, is that at a plane’s cruising speed, it flies most efficiently. This means that the plane can stay in the air for longer. It can also carry more passengers and stay fuel-efficient.

Depending on the aircraft, a plane’s cruising speed can be anywhere from 500 to about 650 miles per hour (about Mach .65 to Mach .85.

For example, the Boeing 787 Dreamliner, a commercial jet, flies at about 650 miles per hour. Its top speed is around 700 mph, which is not that much faster. In fact, it’s not even 10% faster.

Plane Engine

So, flying the plane at max speed would not significantly decrease the duration of the flight relative to the cost the airline will have to pay for using the extra fuel.

Also, if planes flew at their max speed all the time, airfare rates would skyrocket.

Airlines would have to pay thousands of dollars more per flight to get people to their destination. Sure, it may be faster, but not fast enough. You probably don’t want to pay twice as much to save 20 to 30 minutes on a flight. Airplane tickets are already expensive as it is!

As you increase speed toward Mach 1, (about 767 miles per hour – the speed of sound), drag increases exponentially. This drastically reduces fuel efficiency. Not only that, but the wings may tear apart.

In contrast to planes, most commercial jets fly a little faster, around 575 mph to 650 mph.

Pilots use what’s called a cost index to determine take-off speed, cruising speed, and landing speed. Mathematicians use a complex formula to determine these numbers and air traffic control communicates it to the pilots while they’re on the plane.

Cost index describes when you should fly slow to save money on fuel, or when you can afford to fly faster. This costs more but you will get to the destination faster.

A low cost index means that it’s most fuel-efficient to slow down. A high cost index means increasing the plane’s speed is worth it, based on the amount of time that you’ll save.

Typically, if planes are delayed, which costs a lot of money, the cost index increases. This is because it’s more cost-efficient to get to the destination faster.

Cost index is calculated by taking time costs per hour and dividing them by fuel costs per hour.

Time cost includes the following:

  • Maintenance ($ per hour)
  • Cost of engines and auxiliary power units (APUs)
  • Flight crew cost ($ per hour)
  • Depreciation

Each time a plane flies, it gets a little more worn down or depreciates. This means that the value of the plane depreciates, too. So, in other words, airlines lose a little bit of money every time a plane hits the skies.

Think of the last time you bought a car. If you bought it for $25,000 and try to sell it eight years later, the value will depreciate. You might be able to sell it for 8-10 grand, maybe less. The exact price will depend on how many miles you drove it and any repairs it has needed.

So, by accounting for depreciation in this time cost variable, airlines are trying to compensate for that lost money.

Fuel cost is simply the amount of money that fuel costs per hour. This cost can be expressed in pounds/hour, kilograms/hour, or sometimes cost per 100 pounds of fuel used. This can vary widely depending on the airport.

In some of today’s planes, all the pilot has to do is type in the cost index on their controls and it calculates the cruising speed, takeoff speed, and landing speed.

Pilots can’t just fly the plane at any speed they’d like. For one, it’s dangerous, and second, it costs the airline a lot of money. So if they wanted to increase speed for a short period of time, they probably would have to ask the dispatcher for permission.

This can be practical in real-time. For example, if a pilot finds that they have a lot of fuel left and only a short distance left to go, they could increase the speed. Especially on planes with fewer passengers, this is a real possibility.

Why? Well, the more passengers on the plane, the heavier it is. And the heavier the plane, the more fuel it takes to move it.

In contrast, the fewer passengers on the plane, the lower the cost of fuel will be if you speed up.

That wraps up our article ‘Do planes fly at maximum speed?’

In short, max speed is so close to cruising speed that it’s not worth it for airlines to spend the extra money to get passengers to their destination.

The cruising altitude of commercial jets and planes is the optimal range for fuel efficiency. Any higher and the drag increases dramatically – too much to justify flying at that speed. As most commercial planes approach Mach 1, it becomes increasingly unsafe to pilot them, and the wings may tear apart.

How to Clean Luggage (Step-by-Step Guide)

Pink Luggage - How to Clean Luggage

Luggage is a traveler’s best friend, but it can also be a dirt magnet. Even when you’re not traveling, your luggage may get dirty from being shuffled around the airport all the time.

After traveling you’ll want to clean it, too. Then, the next time you travel your luggage will be nice and clean.

Luckily, it’s easy to keep your luggage clean and fresh. We’ll show you how to clean luggage in this step-by-step guide.

1) Empty your suitcase.

First, it’s important that everything is out of the suitcase. Your luggage will be difficult to clean if you’ve got clothes or other items still sitting in the bottom of your suitcase.

2) Vacuum the luggage with an upholstery attachment.

To get the surface dust and dirt, it’s important to vacuum the luggage. You can use a regular attachment or an upholstery brush, whichever is most appropriate for your type of bag and fabric. Be sure to vacuum carefully, as you don’t want to damage the fabric.

If your bag has a lining, be sure to vacuum behind and underneath it too. You’ll also need to take off any zippers or pockets on the outside of your luggage for vacuuming.

Don’t forget about the other compartments in your suitcase as well. Make sure to vacuum out all front, back, and side pockets. If your vacuum attachment doesn’t fit, no problem. Just tip the compartment over and shake your luggage to let the dirt fall out.

3) Mix a squirt of dish soap and water in a bowl.

Dish soap and water is a great DIY cleaner to make sure your luggage is spotless. It helps remove any tough stains and gives pieces a fresh, clean scent.

Simply pour the mixture into your bowl (or washcloth), grab your towel, and start scrubbing away! You can use this mixture on all compartments in your luggage including side pockets or any other surface that needs to be cleaned.

If you need a little more elbow grease, use a scrub brush to loosen up tough stains. This will make it easier to wipe them away.

Don’t use too much dish soap, because it can be a pain to wash out. Start with just a couple of squirts of soap

Avoid bleach and abrasive cleaners. Also, most kitchen degreasers may not be fabric friendly.

4) Wipe the inside of your luggage with a damp towel.

Now you’ll have some soap residue inside your luggage. But that’s not hard to deal with. Just take a damp cloth and wipe it down thoroughly. Be sure that the towel is rung out completely. You don’t want sitting water inside any of your luggage compartments. It may ruin the fabric.

5) Open all the compartments in your luggage and let it air dry outside in the sun.

This can take anywhere from a couple of hours to overnight depending on the material of your luggage. You can dry the surface of your luggage with a towel, but it won’t ever get fully dry unless you leave it out in the sun.

If the weather is poor, just set it on its side on a couple of towels in your home. Make sure all compartments are open; this will speed up the drying process.

Dish soap and water will remove most small scratches and scuffs. Other mild abrasives like baking soda or a commercial cleaner will work great too. For larger scratches, you may need to use a magic eraser pad.

Here’s one that I use in my house all the time from Amazon. It works great!

Baking soda is a fantastic deodorizer for your luggage. Just sprinkle baking soda inside the suitcase and let it sit for several hours. The baking soda will neutralize the smell. Then, vacuum the baking soda in the suitcase. Vinegar is also an effective odor neutralizer. Dip a towel in some vinegar, wring it out, and wipe your suitcase to keep it smelling fresh.
