Can You Wash a Backpack in the Washing Machine?
Most fabric backpacks can be machine washed on a gentle cycle with cold water. Remove all items, turn it inside out or use a laundry bag, and skip the dryer—air dry only. Check the care label first and avoid machine washing leather, vinyl, or backpacks with rigid frames.
Key Takeaways
- Canvas, nylon, and polyester backpacks generally handle machine washing well.
- Leather or faux leather backpacks should be wiped clean, not machine washed.
- Backpacks with cardboard or foam inserts need those removed before washing.
Explanation
Canvas, nylon, and polyester backpacks generally handle machine washing well. The key is using gentle settings to protect zippers, straps, and any waterproof coatings. Empty all pockets completely—small items can damage the machine or get lost. The same gentle-cycle approach works when washing jeans with other clothes.
Before washing, shake out debris and spot-treat stains with mild soap. Remove any detachable parts like hip belts or decorative clips. Place the backpack in a pillowcase or mesh laundry bag to protect it and your machine from strap tangles.
After washing, reshape the backpack and hang it upside down or lay it flat to air dry completely. This can take 24-48 hours. Never use a dryer—heat can melt synthetic materials, shrink fabric, and damage waterproof coatings.
Brands like JanSport, Herschel, and Fjallraven each have different care requirements based on their materials. JanSport's polyester bags are generally machine-washable and the brand even suggests it on their website. Fjallraven's G-1000 fabric (a blend of polyester and cotton) should be hand-washed and re-waxed with Greenland Wax after cleaning to maintain water resistance. Osprey's technical hiking packs with internal frames and hip belts should always be hand-washed to protect the foam padding and structural elements.
Use a mild, dye-free detergent—about half the normal amount—and avoid fabric softener, which leaves a residue that clogs the fabric's pores and reduces breathability. Never use dish soap in the dishwasher or washing machine—it creates excessive suds. Bleach should never be used as it weakens nylon and polyester fibers and can cause color fading. For stubborn odors, add half a cup of white vinegar to the rinse cycle instead.
Things to Know
- Leather or faux leather backpacks should be wiped clean, not machine washed.
- Backpacks with cardboard or foam inserts need those removed before washing.
- For heavily soiled backpacks, pre-soak in a bathtub with mild detergent for 30 minutes.
- Waterproof backpacks may need re-treatment with DWR spray after washing. Bleach can kill mold on fabric, but it may also strip color from your backpack.
- Machine washing may void the warranty on some premium backpack brands—check the manufacturer's care instructions before washing.
