This will also help with the overall health and lifespan of your mattress. We do not recommend applying liquids to the product. Applying liquids may stain the fabric and make the soiled area worse. Moisture or chemicals applied directly to the mattress can cause premature breakdown of the foam and damage the product. We suggest applying baking soda to the soiled area, let stand about 15 minutes, vacuum, and repeat as needed. Air the product out as much as possible. Regular rotation is recommended to ensure even wear and maintain optimal comfort and support. Use a mattress protector to maintain cleanliness and extend the life of your mattress.
