A highly concentrated premium alkaline liquid containing moderate foaming biodegradable detergents. The strong alkaline builders in Master Hood make for the easy removal of carbonized residues, grease, oils, fats, and soils from a variety of surfaces. Safe to use on steel, stainless steel, copper, concrete, and ceramic tile. Special thick and high foaming formula allows the chemical to cling and do the work rather than the cleaning professional. Unlike other hood cleaners, this product will cling longer to the surface allowing for safer cleaning and use.
