Wash in the washing machine, only if you have a front loader. An agitator washing machine may be to hard on this fabric. If you have a top load machine, then wash this cover in the kitchen sink, using warm water and a clear, no dye, type of dish washing soap. Change the water and re wash it, then change the water once again and thoroughly rinse it out. If you have a shop vac, you can vacuum the moisture from the cover. If not, than gently wring the material out and finish removing the moisture with terry cloth towels. Re insert the foam back into the damp fabric and then stand the cushion on end, lean oit on something that moisture will not damage, such as the refrigerator. you can speed up the drying process by placing a fan near by.
