Product Description

What is the best cleaner to remove algae from a boat? With the Nautica XP marine algae cleaner you have powerful non-biocide nano-tech cleaner chemicals to break the bonds of algae and marine growth on the boat’s hull. MAR detergent cleaner works by breaking surface tension holding algae and dirt to the hull and lifting it off for rinsing instead of killing the algae.

On numerous occasions, it has been proven to limit the re-growth of algae infestations better than using sodium hypochlorite and it is ideal as a boat hull cleaner for yachts and boats. Testimonial From Dalgety Bay Sailing Club, Fife, Scotland on this product: “We were most impressed by the test strip we did on our jetty which was very badly fouled, much worse than we would normally let it get.”

It is especially effective on concrete and stone surfaces in harbours, yacht clubs and marinas. The marine algae cleaner is sold as a concentrate and normally dilutes 1 part concentrate to 10 parts water. When used as directed this product does not need an Environment Agency environmental permit for a Water Discharge Activity issued under the Environmental Permitting Regulations. Our customers are very pleased with the performance of this slipway cleaning chemical as shown in this testimonial from North Yorkshire:

Good Morning Ben!

Thanks very much.

We have been using your product in Whitby harbour recently and very pleased with its performance. Getting some in for use in Scarborough now.

Kind Regards
