Since memory foam is like a sponge, it will soak up any liquid that it comes in contact with. We only recommend spot cleaning the memory foam product with a mixture of mild detergent and water. Be gentle when applying any sort of pressure or friction to the memory foam during the spot cleaning. Do not use excess solution and blot the area with a dry towel and some pressure. Do not cover the memory foam with any bedding for several hours to ensure that it is completely dry. Memory foam should never be dried in a dryer. It should be air-dried only. Putting memory foam in your washer or dryer could cause damage to the machines.
