hrmph, Well I gave it a shot, but no real luck...
My pipes are NASTY, I bought it this way I think... I always ride instead of clean.
Anyhow it has tar or rail dust or something that has quite a few black spots all over the pipes. I tried the polish without avail, and I tried some eagle one metal polish(steel wool). This works somewhat, but takes about 20 minutes per little spot to get it out. I don't mind turning all the pipes silver/yellow if I can get them shiny.
Any suggestions?? I'm about to try EZ off oven cleaner.
