Cuprinol Bilgex Bilge Cleaner 1L

This biodegradable bilge cleaner removes grease, scum and oil, leaving you with a fresh fragrance. The product’s biodegradability makes it a lot more environmentally friendly than your average bilge cleaner.

Due to the formula being highly concentrated, very little of it does a lot of work. It’s also harmless to paintwork and fittings when diluted. Approximately 100ml of the product along with 25 litres of sea or inland water is enough to treat a 30ft yacht.

In 2017, Practical Boat Owner tested eight different Bilge Cleaners, examining how quickly they broke down the oil and what the smell was like. In the test, Bilgex produced the best results, emulsifying the oil and leaving no residue behind. It also removed the diesel smell effectively.
