How to wash memory foam
Soak up as much of the spill as possible with a bath towel.
Press the towel over the wet memory foam and hold until the towel is saturated. Repeat the process until there isn't any more liquid to be soaked up.

Possible answers: [I] This heat may wear out the foam, so it's best to soak for five to ten minutes. It's best to wash a large amount of foam at once, especially if you have noticed any splatters or growths on your memory foam. [II] Just make sure to leave an extra few inches of material. Blow dry the memory foam with a blow dryer if applicable. [III] Some people like to place the memory foam in the sink during their shower to soak up the spill, but the plastic might not hold up well to soaking. You might scoop some of the overflow out with the towel; if you don't mind pouring you can run the excess water down your sink before you get the memory foam out. [IV] A bath towel is best for high absorbency, but you can also use paper towels. If the spill can stain, make sure to use a towel that you don't mind getting stained and dirty.
