We only recommend spot cleaning the foam product with a mixture of mild detergent and water. Be gentle when applying any sort of pressure or friction to the 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 foam with any bedding for several hours to ensure that it is completely dry. Mattress or Pillow foams should never be dried in a dryer. It should be air-dried only. Putting foam in your washer or dryer could cause damage to the machines.
