Does not contain ingredients which accelerate metal corrosion Can also be used in conjunction with Deck Wash to brighten teak decks Its green colour makes it easy to see where it has been applied This non-drip gel quickly cleans and removes ugly waterline marks and limescale. To Use Apply the gel with a 2" paint brush to the hull and areas in need of restoration. Watch as the hull returns to its original colour. Leave on for approximately 10 minutes (ambient 10 deg Celsius) then simply wash off with a sponge and fresh water. For areas of lime scale build-up apply light pressure with a sponge or cloth and watch the scale dissolve away. For areas of very heavy build up repeating this process may be necessary. Can also be used on teak decks to brighten the wood. Use Boat Wash first before applying this gel. Leave for a few minutes before scrubbing the wood and rinsing off with water.
