| I don't think I'd dare let them dry out and then expect to get them clean - sometimes too much product absorbed in the foam and depending on the product, may set-up and become impossible to clean out.
It may not always be the case, but one time I remember squeazing a lot of product out of a pad as I was hand washing (which is how I clean them). I suppose they could go through the washer, but I'm more comfortable hand washing them, then set on a shelf in the garage to dry. |
