Grunt! boat cleaner is specifically designed to make cleaning those nasty yellow/brown waterline stains, rust stains from fittings and general gelcoat discolouration on your boat an easy task, so easy in fact you won’t believe it!
Grunt! boat cleaner penetrates into the pores of the gelcoat and using a chemical reaction gently neutralises and magically absorbs the staining without affecting the gelcoat in any way. The stain can then be simply washed off with a sponge and water.
To use Grunt! boat cleaner simply apply to the stained area with a paint brush – wait 20 – 30 minutes or so, longer in colder weather, while Grunt does the hard work, magically neutralising and absorbing the stain and rinse off with a sponge and fresh water, it really is that simple!!!
Whilst primarily designed for use on fibreglass boats Grunt! boat cleaner is also works brilliantly on most two part marine paint systems and yacht enamels typically used on steel or timber boats.
