Also check out the threads "how i fooked up my chrome and parts due to using coke and tin foil !"
coke is fine by it's self as it eats rusty parts and can loosen bits that oil can't get to - so does vinegar
foil scrapes the shit that the coke brakes off and then by rubbing it over the chrome parts, build up and the foil gets harder as it bunched up, and then leaves hair line marks over the surface
for polishing up - peek and a goddards cloth or other soft paste polishes - NOT AUTOSOL
that is a harsh paste
