Thought I would post quick thread to help out those looking to remove rust from hard to reach places without having to replace parts. I used wood bleach (oxalic acid) that you can find at your local paint store and dipped the tricky rusty parts in it over night. Here is a photo of the rear shocks after one was dipped and the other still on the bike. This bike sat in a lean to type shed since 1989 and oxalic acid did its trick!!! I will be happy to answer any questions.
