Care instructions for 100% polyester fabrics can be your reference guide in cleaning your backpack made of the same material.
Polyester is almost always safe in the machine. Here's some washing tips:
- Wash in warm water, never exceeding 120° F
- Use mild detergent, no bleach/chlorine, no fabric softeners
- Do not overload or under-load machine
- Do not mix with other textiles
And if you have something delicate that you know you can toss in the machine but don't really want to risk it, just hand-wash it.
