Fernox Cleaner F3 265ml is a universal, fast-acting, pH-neutral cleaner designed to remove sludge, limescale and installation debris from central heating systems.
Suitable for both new and existing heating systems, Cleaner F3 helps remove contaminants that can affect heating efficiency and contribute to boiler noise. It can also be used when pre-commissioning new systems to remove flux residues and other installation debris in accordance with BS 7593:2019.
Compatible with all metals and materials commonly used in heating systems, including aluminium, Fernox Cleaner F3 can be used with manual or magnetic flushing methods and with powerflushing equipment where systems are heavily contaminated.
One 265ml bottle treats an average domestic heating system of up to 100 litres, up to 12 radiators or 190m² of underfloor heating. It can also be dosed through a Fernox TF1 filter.
