Grunt boat cleaner, does exactly that ~ it takes the GRUNT! out of cleaning your boat. Ugly yellow/brown waterline stains, rust stains from fittings, bird lime and limescale stains, exhaust stains ~ sound familiar? Grunt boat cleaner is specifically designed to make cleaning these hard ~to ~shift nasty stains from your boat an easy task, so easy in fact you won't believe it! Grunt boat cleaner penetrates into the gelcoat pores and using a mild chemical reaction gently neutralises and absorbs the staining without affecting the gelcoat in any way.

The stain can then be simply washed away with a sponge and water. To use Grunt boat cleaner simply apply to the stained area ~ wait 30 minutes or so while Grunt does the work, and rinse off, it really is that simple! Grunt boat cleaner is formulated as a liquid gel in order to adhere to vertical and overhead surfaces. Whilst primarily designed for use on fibreglass boats, Grunt boat cleaner also works brilliantly on most two ~part marine paint systems and yacht enamels typically used on steel or timber boats.

Contains NO harsh oxalic, muriatic or hydrochloric acids.
