Grunt Boat Cleaner 500ml

Grunt! Boat Cleaner

Grunt! Boat Cleaner removes yellow/brown waterline stains, rust staining from fittings, plus bird lime and Limescale from fibreglass gelcoat and painted surfaces.

The gel formula contains no harsh acids and is safer to use than traditional cleaners.

Grunt penetrates into the pores of the gelcoat, neutralising and absorbing the staining by using a chemical reaction. The process is gentle and does not in any way affect the gelcoat.

To use Grunt, apply to the stained area with a paint brush (no mixing or measuring is required). Wait 3-4 minutes (allow slightly longer in colder weather) whilst Grunt does the hard work, then rinse off the area with a sponge or freshwater. It's that simple!

The gel formula adheres to vertical surfaces and works on most two-part marine paint systems and yacht enamels used on steel or timber boats. Safe for use on most surfaces.
