Has anyone heard about using a mix of hull cleaner mixed with liquid patio cleaner to restore badly stained or tarnished gel coat and deck areas of GRP yachts.

Have used patio cleaner on treadmaster to good effect.

Patio cleaner sometimes contains oxalic acid (I believe) which would explain the results.

I think it was the herbicide that did the trick for the treadmaster

Re: Cleaning GEl coat on deck with mix of Patio Cleaner and Hull Clean
Patio Cleaner has hydrochloric acid at 8% dilution, among the ingredients, and it works well on grp hull. I have used it on out boat, and it removes, not only grime build-up, but rust staining, and river water staining very well. I used Mer polish over the hull after washing with fresh slightly soapy (washing up liquid) water.
There is an Australian product with 10% hydrochloric acid as a gel made by khsurfacetech.aust.com (who do not appear to still be trading). I brought some back with me many years ago, and it has almost gone now.
Another good cleaner/polish is Wadpol, that is used on aircraft skins. It was used on jet aircraft in my RN days. This can remove all sorts of gunge, and leaves a polished finish.
