METHOD FOR REMOVING SCALE AND STAINS

摘要

A method for removing scale and stains from the interior surfaces of a water-containing system having a reservoir (1), auxiliary equipment and piping (2, 6-8), without having to drain the water from the system. The use of inhibited mineral acid allows the water to be circulated throughout the entire system, cleaning all interior surfaces (1, 2 and 6-8) without damaging them. Once scale and stains are removed, the water is neutralized.
