Sleek Concentrated Boat Wash Cleaner Shampoo with UV Protection - Rapidly Removes Dirt, Streaks & Algae

Used this on our GRP hull after a long wet winter, so there was plenty of "green" to deal with. This took it off with a soft brush with minimum effort. Gives a bit of a shine too, even without the use of the wax. Our Marina discourages the use of chemicals which may enter the water, so this was brilliant. A little goes a LONG way and it smells fantastic too. Will certainly be buying more when we run out. Recommended it to a couple of other owners too.

Thought I would have a change from my usual Starbright brand as I struggle to remove green build up on my 315 Hanse on Windermere & am keen to find a product that works well & is truly biodegradable. I was very pleased with the Sleek product and overall it worked better that my usual,Its highly concentrated and also works rapidly, I will definitely recommend the product. I also understand its UK made. Thanks.

Bought this a while ago to clean the green from the trees which had built up over the winter.This stuff works really well, my decks came up like new. I also cleaned my spray hood with it and that came up like new as well. I can definitely recommend this product and will be buying again.

This product works very well. It was pleasant to use and I had no issues with it. Good results were easily achieved.

easy to use, excellent results.

This is an outstanding product for anything outdoors if you want to wash it! If you care about the environment and the aquatic life, then this is a must and it washes away all the dirt with very little scrubbing. I only wish our local chandlery had it in stock!
