I have read on these forums of how great oxalic acid is for cleaning hulls. The hull of my newly bought 15ft day boat has a covering of something dark brown which I cannot shift. I've tried chemist shops who can only get me 25kg of oxalic acid. Any ideas on where or how to get about half a kilo of it? preferably in Belfast but I'll travel or pay postage if it can be sent by post. FeeMcGorman
