RE: safe chemicals to clean sails
A while back I took all the advertisers' stickers off of one of Kevin's former sails. It's a tough job which requires considerable elbow grease. I wouldn't do it again. The Bic stickers were worse than the Fiberspar. I figured they would make better sail repair material than the tape sold commercially. Goo Gone sold in the states works best as I remember. The sail is still in good shape. I rigged it a couple of days ago. I tried a number of products, including WD-40, but have cleaned all thoroughly off.
