I suppose I should have mentioned at the beginning of this F4 thread that this bike was in need of a service, thorough cleaning and detail when I purchased it.
We all have our tried and trued methods on anything old and neglected. My simple methods have been used on all the 60’s items I’ve owned, or still own (muscle cars, wooden boats, Schwinn bicycles).
With a bicycle it’s a complete disassembly, wash with Dawn soap, towel off and gently dry with compressed air.
Polish “Only the Paint” with a cleaner such as TR3 with a watered moisten pad being gentle. Just enough to take off decades of oxidation.
NEVER EVER use any cleaner waxes on Screens, Decals or pinstripes. Do the final wax with 100% carnauba, even on the Screens, Decals, etc.
Chrome - wheels, fenders, bars, etc. I use Bronze Wool with a lubricant such as WD-40. When I was a young boy watching/helping an old man restore a classic 60’s Riva boat he told me never to use steel on steel, as in steel wool. The softer Bronze wool will not rust or scratch an old chrome surface.
