ABSTRACT:
A method for removing scale and stains from the interior surfaces of a water-containing system having a reservoir, auxiliary equipment and piping, 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 without damaging them. Once scale and stains are removed, the water is neutralized.
