...clean your boat

Did you know?


  • Detergents containing phosphates can cause local oxygen depletions and may result in the localised suffocation of aquatic life


  • Products used on boat hulls and decks may contain chlorine, ammonia, potassium hydroxide and solvents, all harmful to the aquatic environment


  • Degreasers dry the natural oils that fish need for their gills to take in oxygen


  • Most cleaning products contain chemicals which disrupt the reproductive cycle of fish




  • Use fresh water or non-toxic solutions to clean your boat wherever possible – see the list of alternatives below


  • If you use cleaning products select environmentally sensitive ones – see www.thegreenblue.org.ukfor our product directory and product reviews


  • Washing up, laundry, cleaning toilets


  • Keeping your hull clean before going to a new area will not only be more fuel efficient but also avoid the transfer of non-native species
