Concentrated formula containing citric acid. Contains no mineral acids. Mild organic acids and corrosion inhibitors minimise damage to sensitive metals during descaling and rust removal. Low odour formula does not create acid fumes and is therefore ideally suited for application to food processing equipment. Low foam formulation is ideal for de-scaling pipe-work and circulation cleaning. Removes rust and oxide deposits from ferrous and non-ferrous metals. Excellent treatment for rust removal prior to phosphating, painting or varnishing.
