Each baby play mat is water-resistant but is not 100% waterproof like vinyl. To properly care for your baby floor play mat, make sure to wipe out any liquid (pee, poo, and milk). Check the bottom of the mat regularly. If the liquid stays on the cover for an extended period of time, the moisture will eventually get inside and damage the surface and foams, as warm and moist soft foam can create an environment for mold to grow.
 Mold will not be considered defective and not be covered by warranty.
