Builders Kleen is a great problem solver for many industrial tasks; a powerful descaler. It removes rust and iron deposits, excess gout and mortar.

It provides a safe and environmentally friendly solution to clean brick walls. It is an organic salt and as such in non-corrosive, non-fuming and rated only as a mild irritant towards people. However in the presence of reactive deposits such as calcium carbonate and calcium sulphate, Builders Kleen behaves just like hydrochloric acid, rapidly dissolving scale and calcium deposits. It's fast acting and easy to use.

Available in 1L, 5L, and 15L.
