Chesterton’s 346 Descaler & Chemical Cleaner is a concentrated, acid-based liquid cleaner formulated with a metal protecting inhibitor. It removes inorganic soils and coatings such as hard water deposits and rust in a wide range of applications.

Unlike other acid-based cleaners, the product will not aggressively attack base concrete or metal surfaces, or any adjacent metalwork. 346’s high quality formulation contains a selective metal protecting acid inhibitor to protect surfaces from attack.

By simply by changing the dilution, you can use the product in areas ranging from the boiler room to the warehouse floor and on surfaces from concrete to metal.

In closed systems, 346 Descaler and Chemical Cleaner can be used to remove hard water build-up, lime, scale and corrosion. When used in steam boiler tubes, the product brings boilers back to top efficiency and saves expensive fuels.
