Whether you’re commuting on a busy subway or trekking up a dusty mountain, travel can be a messy business. And no garment takes the hit quite like the bag on your back. 

Luckily, learning how to wash a backpack can keep your bag fresh for adventures and extend its lifespan. Just remember, not all backpacks are made the same—some are machine washable, while others need hand-washing.

In this guide, we explain how to clean a backpack, evaluate if it's safe for the washer or dryer, and keep it in great condition.

How to Wash a Backpack by Hand

If your backpack needs a little extra TLC, hand-washing is best. Delicate fabrics like leather or water-resistant coatings (like the one used on CALPAK’s Terra Hydration Backpack) can get damaged in the wash. 

Similarly, hiking packs with complex frames or vintage designs also benefit from a gentler touch. If your bag has padding, embellishments, or special features (like this Terra Backpack Duffel) hand-washing helps keep it in great shape.

Supplies Needed

Before we explain how to wash a backpack by hand, we first need to check you have all the right supplies. Here’s what you’ll need: 

  • Mild, unscented soap or detergent
  • A soft sponge or washcloth
  • Gentle cleaning brush
  • Towels for drying

Okay, now on to the actual cleaning…

Step 1: Empty and Prepare the Backpack

Before you start, you need to remove everything from the backpack. Make sure you open all compartments, shake out any sand and crumbs, and turn it inside out for a thorough cleaning. You can even vacuum the seams and crevices in the pockets to remove any remaining loose dirt.

Be sure to check for wrappers or tissues that could break apart when washed—we all know how tricky removing those shreds of lint-like paper is!

Step 2: Check the Care Label

You wouldn’t wash your favorite sweater on the wrong settings or put your best waterproofs in the dryer, right? Well, your backpack deserves that same care too.

To find the best way to clean it, be sure to check the care instructions inside your backpack. They’re usually written on a white label in the main compartment that is sewn into the side seam. This will help you understand any specific guidelines for cleaning or drying.

Step 3: Spot-Clean Any Stains

You know what we said about extra care? It applies to the cleaning process too. Before washing the entire bag, check for stains that need a little extra elbow grease. Be sure to look at the areas that get the most wear, like the straps or bottom.

Then, use a soft brush or sponge and a small amount of mild detergent to gently scrub the dirty areas. Remember to take your time here. It may take a few tries to plot out the larger spots.

Step 4: Hand-wash in Lukewarm Water

Time for the big plunge! Fill a basin with lukewarm water (you want about 6” of water to completely submerge your backpack) and add detergent. Then, gently agitate the water to form bubbles and use a sponge to carefully wipe the interior. Scrub the exterior too, paying extra attention to high-contact areas like the shoulder pads and lower back. 

If your bag is particularly dirty and the water turns brown, you may want to change the water and wash the bag again.

Step 5: Rinse and dry

By now, your backpack should be sparkling! All that’s left to do is rinse it thoroughly with cool water until it runs clear. Then, hang it upside down to air dry in a warm spot, though avoid direct sunlight and radiators.

How to Wash a Backpack in a Washing Machine

I think we can all agree that backpacks take a beating, from daily commutes to weekend adventures. The Diaper Backpack with a laptop sleeve or this Connect Laptop Backpack are both perfect for work and family duties, so they’re bound to pick up some scuffs and marks.

If yours is made of durable materials like nylon or polyester and doesn’t have delicate details or internal frames (something like CALPAK’s Luka Laptop Backpack), you can refresh it with a gentle spin in the washing machine.

Supplies Needed

It goes without saying that you need a washing machine for this one! But you’ll also need:

  • Gentle detergent
  • Laundry bag or pillowcase
  • Towels for drying

Step 1: Prep the Backpack

Before your backpack can go into the washer, you first need to empty all compartments and shake out any loose dirt. If it’s particularly messy, you might want to quickly vacuum the interior too. 

Next, brush off the sand or mud from the exterior (you can either use your hand or a wire brush here) and detach any removable straps or accessories. 

Be sure to unzip all compartments and turn the backpack inside out to protect the zippers and pockets during the wash.

Step 2: Use a Laundry Bag or Pillowcase

Even if your backpack is sturdy enough to survive a machine wash, you still need to protect it. We recommend placing the backpack inside a mesh laundry bag or an old pillowcase. This stops straps from tangling and keeps the backpack from rubbing against the sides of the machine.

Step 3: Wash on a Gentle Cycle

You want to take extra precautions at this step too. Add a mild detergent to the drum and set your washing machine to a gentle cycle with cold water. Avoid using bleach or harsh cleaners, as they can damage the material and fade colors.

Step 4: Air Dry

We know it’s inconvenient but you really shouldn’t put a backpack in the dryer. The high heat can damage the fabric and structure. 

Instead, after washing, allow the backpack to air dry. Hang it upside down with all compartments open to ensure thorough drying and prevent mildew from forming. 

Maintenance Tips For Keeping Your Backpack Clean

We’ll let you in on a secret: regular backpack maintenance can help it last longer. It also means you won’t need to wash it as frequently. 

With that in mind, here’s how to keep your bag in great shape and ready for your next adventure without worrying about heavy-duty cleaning sessions.

  • Routine Cleaning: After each use, give your backpack a quick wipe-down with a damp cloth or sponge. This prevents dirt and grime from building up, especially on the bottom and straps. It’s a small step that makes a big difference over time, keeping your backpack fresh for the long haul.
  •  Zipper Care: Bags with lots of zippers, like this Luka 15” Laptop Backpack, need regular cleaning as zips can easily become clogged with dust, leading to sticking or even breakage. To keep them running smoothly, periodically clean the zippers with a soft brush or cloth. You can also apply a small amount of zipper lubricant to ensure they glide smoothly.
  • Avoid Overpacking: Overstuffing your backpack can stretch the fabric and wear down the seams. Instead, try to pack only what’s necessary. If you need extra space, consider a larger option like the Terra Large 50L Backpack Duffel, which is roomy enough to fit plenty without overfilling. This will help keep your go-to bag in better condition and prevent unnecessary wear and tear.

FAQs

Can You Put a Backpack in the Dryer?

We’ll get straight to the point here: tossing your backpack in the dryer is a bad idea. The heat can shrink fabrics like nylon or polyester and mess up zippers, straps, and padding. Instead, after washing, just air dry it.

Open all the pockets and hang it upside down in a well-ventilated spot out of direct sunlight to avoid fading. It might take a while to dry, but this method keeps your bag looking good for longer.

How Long Does it Take for a Backpack to Dry?

Depending on the size and material, it can take anywhere from 24 to 48 hours to fully dry.

Nylon and polyester backpacks dry faster, while thicker, padded ones need more time. Sure, it’s a bit of a wait, but letting it air dry is the best way to keep your backpack in tip-top shape!

How Do You Clean a Nylon Backpack?

Cleaning a nylon backpack is a breeze! Just remember to empty all compartments and give it a good shake upside down to remove dirt and crumbs.

For light cleaning, wipe the inside with a damp sponge and gently scrub marks with a mild soap. For a deeper clean, put it in the washing machine and let it air dry in the shade.

How Do You Clean a Leather Backpack?

Cleaning a leather backpack takes a little extra care. Start by emptying the bag and wiping the surface with a dry cloth to remove dust. Avoid the washing machine and instead, mix mild soap with warm water and gently wipe down the leather with a damp cloth.

Avoid soaking it—leather and water don't mix well. After cleaning, apply a leather conditioner to keep it soft and prevent cracking. Let it air dry fully, away from direct heat or sunlight. Leather backpacks, like the Kaya Mini Backpack, need to be treated with love and care.
