Backpacks go everywhere with us—from daily commutes to outdoor adventures, school, flights, and weekend trips. Over time, sweat, dirt, food spills, dust, and stains build up. Washing your backpack regularly helps maintain hygiene, extend its lifespan, and keep fabric and zippers functioning properly.

But the big question is: Can you wash a backpack in the washing machine? Or is hand washing the safer method?

This complete guide explains how to wash a backpack safely—by hand or in the washing machine—without damaging the fabric, water-repellent coating, padding, or structure.

Can You Wash Your Backpack?

Most backpacks can be washed, but the method depends on materials and construction.

Backpacks that can be machine-washed:

  • Soft-shell nylon backpacks
  • Polyester backpacks
  • Lightweight travel backpacks
  • Non-leather, non-structured bags
  • Bags without rigid frames

Backpacks that should NOT be machine-washed:

  • Leather backpacks
  • Backpacks with metal frames
  • Backpacks with glued structural foam
  • Waterproof dry bags
  • Hiking bags with internal metal rods
  • Bags with leather trims

Purevave’s laptop backpacks are made from water-repellent nylon, lightweight EVA foam, and durable TPU-coated zippers. These materials are designed for easy cleaning, making both hand-washing and gentle-machine washing safe when you follow the correct steps.

Before Washing: Important Preparations

No matter which cleaning method you choose, always do these steps first.

Empty the Backpack Completely

Check all pockets—including hidden ones—for:

  • Coins
  • Paper
  • Pens
  • Keys
  • Headphones
  • Snacks
  • Makeup
  • Receipts
  • Crumbs
  • Chargers

Turn the backpack upside down and shake it gently.

Remove Dust, Dirt & Debris

Use:

  • A handheld vacuum
  • A lint roller
  • A soft brush

Removing loose dirt makes washing far more effective.

Check the Care Label

Most backpacks include a label inside the main compartment.
Check for:

  • Machine-wash instructions
  • Water-temperature instructions
  • Air-dry recommendations

Purevave backpacks are designed with easy-clean materials, but hand-washing is always the safest universal method.

Remove All Detachable Parts

If applicable:

  • Shoulder pads
  • Removable straps
  • Hip belts
  • Internal boards
  • Metal frames

Purevave laptop backpacks have lightweight, soft constructions with no rigid frames—making washing straightforward.

Pre-Treat Stains

Use mild soap or stain remover on:

  • Ink
  • Food spills
  • Mud
  • Sweat stains
  • Oil stains

Rub gently with a toothbrush for 1–2 minutes.

How to Wash a Backpack by Hand (Safest Method)

Hand washing is the best choice for backpacks with:

  • Water-repellent coatings
  • Delicate zippers
  • EVA foam padding
  • Laptop compartments

This method maintains the bag’s structure and extends its lifespan.

What You’ll Need

  • Mild detergent (no bleach)
  • Lukewarm water
  • A soft brush or sponge
  • A toothbrush for corners
  • A bathtub, sink, or basin
  • Towel

Step-by-Step Hand-Wash Guide

Fill the Tub with Lukewarm Water

Avoid hot water—it can damage fabric, protective coating, or glue.

Add Mild Detergent

Use:

  • Baby-safe detergent
  • Gentle liquid soap
  • Fabric-friendly detergent

Avoid harsh cleaners, bleach, or strong chemicals.

Submerge the Backpack

Dip it slowly so air escapes from the padding and pockets.

If your backpack has a structured base (like Purevave’s Travel Carry-On Backpack), submerge only up to safe levels or wash section-by-section.

Scrub the Fabric Gently

Use a soft brush for:

  • Straps
  • Shoulder padding
  • Mesh pockets
  • Bottom panel

Use a toothbrush for:

  • Zipper tracks
  • Small corners
  • Logo areas

Rinse Thoroughly

Rinse with clean water until detergent is fully removed.
Soap residue can leave marks or affect water-repellent coatings.

Remove Excess Water (Do Not Twist)

Press gently using your hands.
Twisting can deform straps or internal padding.

Air-Dry Properly

Drying tips:

  • Hang upside down
  • Open all zippers
  • Allow airflow inside pockets
  • Keep in a ventilated place
  • Avoid direct sunlight (can fade nylon)
  • Never use a dryer (heat damages structure)

Purevave nylon dries quickly thanks to its lightweight, soft construction.

How to Wash a Backpack in the Washing Machine

Machine washing is faster—but must be done carefully.
It’s suitable for soft-sided nylon backpacks, including Purevave’s laptop backpacks, 
if washed gently.

Backpacks You Can Put in the Washer

  • Nylon
  • Polyester
  • Lightweight daypacks
  • Purevave laptop backpacks (gentle cycle only)

Backpacks You Should NOT Machine Wash

  • Leather
  • Thick hiking backpacks

Machine Wash: Step-by-Step Guide

Put the Backpack in a Laundry Bag/Pillowcase

This protects:

  • Zippers
  • Straps
  • Buckles
  • Washing machine drum

Use Gentle Detergent

Choose:

  • Mild soap
  • Baby detergent
  • Liquid detergent (better than powder)

Set Machine to:

  • Cold or lukewarm water
  • Gentle cycle
  • Slow spin speed
  • No bleach
  • No fabric softeners

Heat can damage backpack structure and affect water-repellent coatings.

Run an Extra Rinse Cycle

Ensures all soap is removed.

Air-Dry Carefully

Do not put your backpack in the dryer.

Drying tips:

  • Hang upside down
  • Air in shade
  • Open all compartments
  • Keep away from heaters

Purevave’s ultra-light nylon dries fast—usually within hours.

How to Clean Backpack Zippers Properly

Zippers are the most-used part of any backpack.
Keeping them clean ensures long-lasting performance.

Cleaning Steps:

  1. Use a toothbrush to brush dirt out of the zipper teeth.
  2. Rinse gently with water.
  3. Wipe with a microfiber cloth.
  4. Optional: Apply zipper lubricant for smoother glide.

Purevave backpacks use TPU-coated zippers, designed to resist water and wear—making them easier to clean and maintain.

How to Remove Bad Smells from a Backpack

If your backpack smells like sweat, food, or mildew, do this:

Use Baking Soda

  • Sprinkle inside
  • Leave overnight
  • Shake out the next day

Use Vinegar Spray

  1. Mix 1:4 vinegar & water
  2. Spray lightly
  3. Air-dry in a ventilated area
