摘要：
The invention concerns the use of hydrogen sulphate, particularly in the form of sodium, potassium or ammonium hydrogen sulphate, as the acid constituent in methods for the removal of manganese-containing and/or iron-containing deposits and/or incrustation from drinking water supply equipment made of special steel or including special-steel elements, the methods making use of aqueous treatment compositions containing an acid constituent as their first active ingredient in conjunction with hydrogen peroxide or hydrogen-peroxide-forming compounds as their second active ingredient, the use of hydrogen sulphate ensuring that corrosion of the special-steel parts is avoided.
