Hot Shot is a strong detergent designed to remove heavy buildup from metal surfaces. It is excellent for cleaning ovens, deep fryers, and other kitchen equipment. Hot Shot is not suitable for use on aluminum, galvanized, or other alkali-sensitive surfaces. This premium, heavy-duty alkaline paint and rust stripper is designed for use on ferrous, magnesium, titanium, and copper metals. It dissolves rust, prevents metallic sludge formation, retards re-rusting of metal, and is effective in both hard and soft water.
