CalDescaler loosens and dissolves limescale, corrosion deposits and iron oxides typically found in heating systems with circulation and heat transfer problems. Calmag recommends using the CalDescaler for the boiler (heat exchanger) only. Research has shown that limescale only forms above 70 degrees in a sealed system and is therefore not required in the radiators or pipework. Dose system with 1/2 litre (half a litre bottle) per 100 litres of water using a powerflush machine. 

Can be water neutralised.

Dissolves limescale quickly and effectively.

Safe for use on steel, stainless steel, iron, copper, brass, rubbers and plastics.
