Descaler SF (AFCO 3196) is a free-flowing inhibited inorganic acid type descaler. It has been scientifically formulated using Sulfamic acid together with inhibitors to provide safety in handling and reduced corrosive attack. AFCO 3196 is generally recommended for removing scale on exterior and interior surfaces of boilers, heat exchangers, vats, shackles, kettles, stainless steel equipment, etc. and for removing cement, plaster, lime, etc., from brickwork, stone and ceramic surfaces. It rapidly attacks calcium and magnesium salts and oxides.
