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 lime scale 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. 1-litre.
