Boiler Scale - Boiler Chemical Treatment Products

Boiler Scale Steam boiler cleaning is a routine water system maintenance in which deposits like calcium are removed on the boiler surface through the use of a descaling acid. Impurities tend to accumulate in boilers through constant use which can insulate water from the heat source, especially if heat exchangers in the system use tap water.
