Naturepedic's Product Registration

To clean your waterproof crib mattress, simply wipe the surface with a damp cloth. You can use a mild cleanser on the soiled surface or some hydrogen peroxide (3%) or rubbing alcohol to sanitize. All breathable models have removable machine washable covers, and the waterproof surface underneath can be cleaned per the previous waterproof instructions. 

Crib mattresses with quilted surfaces are not waterproof and are spot clean only. For these models, we recommend using an organic waterproof protector pad to prevent fluids from seeping into the mattress.
