Hull gelcoat cleaning

My M lives in the river Tamar all summer, this is a filthy brown river and within a short time of the boat going in, quickly builds up nasty brown staining above the waterline which is a real pig to get rid of. I've tried Jif, and other household cleaners, and even tried T cut with very little success, can anyone recomend a decent cleaner which will leave my hull looking pristine again please?

I use Starbrite Seasafe hull cleaner which works really well - no rubbing or scrubbing - it claims to be environmentally safe and not to contain any strong acids - I think it contains oxalic acid. They do a stronger cleaner as well

You can buy oxalic acid on t'internet - very cheap

Hi Paul
My M lives in storage most of it's life. I bring it home in the spring and park it on the drive and give it a good clean.
The white deck is more green than white.I use a sponge scouring pad and scouring powder such as Vim or Ajax hard to source today but it is
out there.This is a severe cut clean and care is needed. Result you need to were snow glasses. the white is that brite.
If you try this method on the stain at water line. try on a small area not so obvious to the eye. you will need to T-cut after to polish.
Hope this helps

For routine cleaning above the water line I have found Autoglym caravan cleaner to be good - makes the white white.

The scouring paste (I use "Astonish") is the only thing that I have found will get rid of that horrible grey/black pitting on the hatch strips - ie the ones that the top hatch slides under and also the 2 vertical facing ones that hold the door in place.

Hi,

I use Ecover Heavy Duty Boat wash and Ecover Wash and Wax. It works well (though I do use a set of cheap toothbrushes for detailing) and it seems to be one of the few products where my green conscience doesn't collide with my economic realities. It is pretty well priced. Oxalic acid is great to get rid of calcium build up (limescale) and rust spots. Quite irritating to skin, eyes etc., though. So you should wear gloves and :geek: goggles. Buy it as dry powder and dilute 100g to 1l of water. You can get a kg on fleebay for a few quid, my chandler sells a tiny bottle of a gel like solution for double the price !
