The Fernox F3 Central Heating Express Cleaner Aerosol 400ml is a highly effective, universal pH-neutral, non-foaming cleaner designed to remove sludge, scale, and debris from existing central heating systems. This restores heating efficiency and eliminates boiler noise. It is also ideal for commissioning new systems, removing flux residues, and other installation debris, thus extending the boiler's life and system efficiency. Using Barrier Pressure Pack technology and compressed air propellant, this product ensures a non-flammable and safe application without the risk of air ingress, which could accelerate future corrosion.

• Quick and convenient to use, dosing in 30 seconds with no need to drain the system.
