Your NextCover bag best protects your gear when clean, inside and out.
Should it become dirty, you can spot clean it by treating the stain with a mild/organic stain removal product and gently wiping with a cold, damp, soft cloth. The exterior of coated polyester covers also cleans nicely with a commercial cleaning wipe.
The entire cover can also be machine washed. Fully unzip the cover prior to washing. A 1x cover will fit in most standard-sized washing machine tubs, but larger items may require an industrial-sized tub, available at many laundromats. Use a gentle cycle, with cold wash/cold rinse, and a mild detergent. Line dry only; do not put in the dryer.
Never use bleach or harsh cleansers on your covers, never scrub vigorously, and never use a brush or any kind of rough sponge or cloth.
