I am restoring an early 70's Raleigh Super Course and the alloy handle bar and wheels have some oxidation. How do you treat oxidation and what cleaning chemicals to use? I'm thinking of vinegar or chlorox but before I do so, maybe someone out there with a better idea to approach this problem. I rode the bike yesterday and seems like everything works except I need to replace the rear tube and tire since it is cracking on the sidewall. Have done the replacement on the front wheel so far and the new tire look good.
