Fernox Cleaner F3 500ml is a universal, pH-neutral, non-foaming central heating system cleaner designed to remove sludge, limescale and other debris from existing heating systems.
Cleaner F3 can help restore heating efficiency and reduce boiler noise caused by system contamination. It can also be used when commissioning new heating systems to remove flux residues and installation debris before the system is protected with a central heating inhibitor.
Suitable for all metals and materials commonly used in heating systems, including aluminium, Fernox Cleaner F3 can also be used with powerflushing equipment to accelerate the cleaning process in existing and contaminated systems.
One 500ml bottle treats up to 130 litres of system water, up to 16 radiators or up to 250m² of underfloor heating.
