How to Wash a Backpack — The Complete, Friendly Guide

Introduction

Backpacks travel with us everywhere—commutes, weekend trips, gym sessions, and grocery runs. Over time they collect dust, sweat, crumbs and the occasional mystery stain. The good news? Most backpacks can be cleaned at home with simple tools and a little care. This guide walks you through machine washing and hand washing, material-specific care (nylon, polyester, canvas, leather), how to dry your pack safely, and quick tips for keeping your bag looking and smelling fresh. Read on — your backpack will thank you.

How to wash a backpack in the washing machine

When machine-washing is OK

• The care label explicitly allows machine washing.

• No full leather construction or glued-on leather trims.

• No rigid internal frames that would bend or damage in the wash.

Prep checklist (do this every time)

1. Empty all pockets and shake out crumbs and debris.

2. Remove detachable parts: straps, hip-belt, removable laptop sleeve, if possible.

3. Close zippers, fasten buckles, and tuck in straps to avoid tangling.

4. Spot-treat visible stains before the wash (see stain tips below).

5. Place the backpack in a laundry bag or pillowcase and zip/ tie it closed.

6. Add a few towels to balance the load and cushion the backpack.

Best machine settings

• Cycle: gentle / delicate.

• Water temperature: cold or lukewarm (never hot).

• Detergent: mild liquid detergent (no bleach, no fabric softener).

• Spin: low spin or skip heavy spins to protect padding and structure.

After the wash

• Remove detergent residue by checking seams and pockets; if present, rinse by hand.

• Reshape the bag and air dry (see drying section).

What to avoid

• High heat, strong agitation, bleach, and tumble-drying on high.

• Machine washing backpacks with leather trims or glued decorations.

Troubleshooting

• Persistent smell after wash: air dry thoroughly; consider a baking-soda rub or brief vinegar rinse (see hand-wash section).

• Squeaky/dry zippers: apply a zipper lubricant after the pack is fully dry.

How to wash a backpack by hand

When to choose hand washing

• Backpacks with leather trims, glued parts, or delicate prints.

• Structured packs with foam padding or internal frames.

• When the care label forbids machine washing.

Step-by-step hand-wash method

1. Empty and prep: remove all items and detachable pieces. Shake out debris.

2. Make a cleaning solution: lukewarm water + a small amount of mild detergent (or dish soap for oily stains).

3. Spot-treat stains: apply detergent directly (or a paste of baking soda + water), let sit 10–15 minutes.

4. Clean gently: use a soft brush or sponge to scrub seams, pockets, and stained areas. Use a toothbrush for tight seams and zipper channels.

5. Rinse thoroughly: use clean water and squeeze (do not wring) until water runs clear.

6. Remove excess water: press with a towel to absorb moisture; avoid twisting.

7. Air dry: reshape and dry in shade (see drying section).

Odor-fighting options

• Baking soda soak: sprinkle baking soda inside the bag, leave overnight, then shake out and vacuum.

• Vinegar rinse: mix 1 part white vinegar to 4 parts water for a quick rinse (test hidden area first), then rinse well with plain water.

How to clean nylon backpack

About nylon

Nylon is lightweight, strong and resistant to tearing—common for daypacks and sporty styles.

Cleaning tips

• Machine: usually safe on a gentle cycle if there are no leather trims or internal frames.

• Hand: safe and recommended if you want to be extra cautious.

• Stain removal:

  • Oil/grease: apply dish soap directly, gently rub, rinse.

  • Ink: rubbing alcohol on a cotton swab (test in hidden area first).

  • Sweat: soak the straps in warm water with detergent before washing the whole bag.

• Drying: air dry in shade; nylon dries quickly but avoid heat that can warp coatings.

How to clean a polyester backpack

About polyester

Polyester is durable and commonly treated with water-resistant coatings—it's the material used for Cinomadist backpacks.

Cleaning tips

• Machine: safe in most cases on gentle cycle with cold/warm water. Use a laundry bag to reduce abrasion.

• Hand: ideal for heavily printed or coated polyester.

• Stain removal:

  • Coffee/tea: blot immediately, pre-treat with detergent, launder.

  • Salt/weather stains: rinse with fresh water, then wash.

• Protect coatings: avoid aggressive solvents and hot drying which can break down water-repellent finishes.

How to clean canvas backpack

About canvas

Canvas is sturdy and classic-looking, but it can shrink or lose dye if treated harshly.

Cleaning tips

• Prefer hand washing or a very gentle machine cycle. Test colorfastness in a hidden area.

• For small stains: scrub with a soft brush and mild detergent.

• Mold/mildew: scrub with a mixture of equal parts water and white vinegar, then rinse thoroughly and dry in sun briefly (sun helps kill spores, but avoid long direct sun for colored canvas).

• After cleaning: consider reproofing (wax for waxed canvas) or a fabric protector spray to restore water resistance.

How to clean a leather backpack

Important rules

• Never machine wash leather. Water, heat and harsh detergents can damage leather’s oils and structure.

Cleaning steps

1. Remove dust with a soft, dry cloth.

2. For surface dirt: use a slightly damp cloth and a small amount of mild soap (saddle soap or a recommended leather cleaner). Wipe gently.

3. For stains: consult a leather specialist for ink or deep stains. Avoid DIY chemical treatments.

4. Conditioning: after cleaning and when dry, apply a leather conditioner to replace natural oils and keep the leather supple.

5. If the leather gets wet: blot excess water, stuff with paper to preserve shape, and air dry away from direct heat.

How to dry a backpack after washing it

Best practices

• Reshape the bag and open all zippers/ pockets so air circulates.

• Air dry in a well-ventilated, shaded area — direct sunlight can fade colors and damage coatings.

• Stuff the bag with dry towels or crumpled paper to help it keep shape and absorb moisture from the inside. Replace stuffing if it becomes wet.

• Use a fan to increase airflow if needed. Avoid direct heat sources (radiator, hairdryer on hot).

• Wait until completely dry before storing or using; damp pockets encourage mildew.

Quick-dry tips

• Press with a towel to remove excess water before hanging.

• Hang so the opening faces down slightly to let water drain from seams.

• For faster drying of padding, unzip and spread foam sections if possible.

Quick tips, common mistakes & FAQ

Quick tips

• Always check the care label first.

FAQ

• Can I wash a backpack with a frame? If the frame is removable — yes after removing it. If it’s fixed, hand wash and avoid full immersion.
