This cleaner is ideal for ventilation, microwaves, cooktops, refrigeration, and stainless steel surfaces. It easily removes burnt-on debris and greasy residues. Can be used on kitchen cabinets, countertops, tile and steel. Maximum exposure time for aluminum is 15 minutes. Do not use on control markings, labels, logos, foil or anti-fingerprint (AFP) coatings, black or easy clean steel, and oven interiors. Black steel and easy clean steel can be cleaned with mild, soapy water and a soft cloth.
