Fast-acting cleaner designed to quickly remove limescale, black sludge, magnetite and other system contaminants from domestic heating systems. Fernox DS40 is a free-flowing, citric-acid-based cleaner that is ideal for powerflushing and can also be used for separately descaling a boiler component or heat exchanger.
DS40 turns red-yellow to indicate that the product is exhausted and more powder needs to be added. When the clean is complete, add the contents of the included bottle of System Neutraliser until the solution turns yellow.
