DO NOT use heat to dry equipment as this can cause premature, unseen damage to the surface materials and internal padding which will excelerate wear. Lightly scrub the item, using a sponge, and then rinse thoroughly. Item should be allowed to air dry. DO NOT submerge any item in water because item will most likely not be able to dry properly. Moist areas, that do not dry properly can form bacteria and mildew.
Shrinkage is more likely to occur on soaked items as well.
A washing machine is not recommended as water pressure can cause premature separation of coatings on external materials. Never use fabric softener on your equipment for the same reason. This will also help keep unit cleaner longer. Any kind of treatment that is being applied should be tested on a small area for compatibility before use. Some commercial equipment, that is designed for the cleaning of sports equipment, is available.
