To care for a polyurethane finish, wash or wipe with a damp cloth. Do not use sprays, waxes, amonia-based cleaner, cleansers or liquid silicone wipes. They only lay on the surface and gather dirt! To care for a water based finish, the same thing applies… use only a damp cloth! At most, a dish cloth with warm water and Dawn will clean up any messes! Easy-peasy!
