Thanks for the tips. It is rust that I'm trying to get off. The thing is that it is only small spots of rust and I didn't want to have to get into to much elbow grease to ruin the frame. I though that someone may know of something that I can put on a rag and wipe off the rust just long enough to put some touch up paint on it if needed and get the bike put back together. After all I give these bikes away and although I like them to look as good as they can and be safe at the same time, I don't like to spend a whole lot of time on them .
