For fast-acting removal of limescale, black sludge (magnetite) and other deposits from boilers and central heating systems. Designed for use with powerflushing units for more efficient, rapid cleaning. Can be used separately to descale a boiler.

Application & Dosage

For detailed instructions on the cleaning of central heating systems using DS40 System Cleaner, please refer to the instruction leaflet inside the box. The product can be poured as a free-flowing powder directly into a powerflushing unit. Alternatively, by pre-dissolving in warm water, the product can be applied via the F&E tank or, in a sealed system, via a Fernox Injector into a radiator. One box (1.9 Kg) is usually sufficient to clean a typical domestic central heating system. For large systems and heavily scaled or sludged systems, additional powder may need to be added. During the early part of the clean, a colour change (red-yellow) indicates that the product is exhausted and more powder needs to be added.
