SEPTONE Drifter Hull Cleaner & Stain Remover 5L Phosphoric Acid Based 

Drifter is an acid based cleaner incorporating a biodegradable surfactant which cleans and revives and removes rust stains from fibreglass gelcoat, painted timber surfaces and from steelwork. Drifter will also de-yellow gelcoated and 2-pack painted surfaces. It is an ideal cleaner for fishing trawlers and for any boating enthusiast.

Ideal for de-yellowing gelcoats/fibreglass, its phosphoric acid formula is most effective at removing rust stains, converting rust and inhibiting its reformation. Used at the recommended concentrations it will not cause streaking or effect painted surfaces providing it is washed off before drying.

Drifter may also be used in food preparation areas and other applications involving the removal of rust stains from stainless steel.
