STAR BRITE Instant Hull Cleaner - Easily Remove Stains, Scum Lines & Grime for Boat Hulls, Fiberglass, Plastic & Painted Surfaces - Wipe On, Rinse Off Formula

This stuff works - just don‘t wear cloths that you want to wear again :). Wear gloves and maybe some eye protection + hat if working on areas above head height.

This product worked well but did take some persistent scrubbing to remove stains there are some me stronger products out there that take less work

Was sceptical but it works exactly as it says and does an astonishing job

Worked very well on the boat hull . Use white non scratch kitchen pads with it

Over rated, really does not work on stained gelcoat...

Used this to clean off the brown water stains on the hull at the end of the season. Normally this takes a load of scrubbing but this cleaner is amazing. You just paint it on and wash it off. It literally starts working straight away.

Into a spray bottle. Spray and leave for a few minutes. U can see it working. Wash over and all the grime has gone. Have been using this cleaned for years. Nothing else beats it

absolutely rubbish this product does not work and is very expensive DO NOT WASTE YOUR MONEY PEOPLE

Können wir nur weiter empfehle.

Excellent produit qui efface parfaitement les traces jaunes grasses laissées par les produits solaires, le long de la ligne d'eau sur la coque de la piscine. Parfait.

Prudito top

No vale la pena no blanquea no quita el amarillento

Produit efficace, de l'acide oxalique en plus cher ...
