Hi Dominic and Nicola, I remember an article by someone in Practical Boat Owner in the not so distant past, recommending Astonish cream cleaner( used on ovens etc.) to clean up GRP. I tried it and it was great removing stains on my old boat. It is cheap and not tested on animals. Good luck. Regards Marie

Someone some time ago posted a very useful piece of advice on a method of easily removing rusty stains that often crop up on GRP surfaces. I have trawled the forum but cannot find it. Our 'rusty' stains are actually from a red-leaved Acer tree that overhangs our Pilot on the front drive. It sheds huge quantities of leaves that have leached red/rusty marks all over the boat. Although the tarp is now on to protect it, I'm left with some serious elbow grease style scrubbing? Any suggestions anybody on a solution/solvent? to speed the work up? Dominic and Nicola.
