We've been testing some different formulations for a specialty appliance seal & surface cleaning which we call the "appliance nook & cranny" spray. Appliance seals and other nooks get built up with a combination of mold stains, detergent, human matter, hair, and other gunk which can be very stubborn. Our formulation considers all of these types of stuck on messes to break down and clean them, without harming the rubber seals and other surfaces
