The bottom yoke, or triple clamp depending on where you're from, is a pain in the ass to clean because of the strengthening sections cast in at the factory. Too difficult to get a wire brush in, too much like hard work to use emery cloth and I don't have access to a shot blaster.
I dropped it in a tub of vinegar for a week, washed it in water with a scotch pad and, hey presto, it came up pretty good.

And then we go back to the "crazing" paint on the ally parts. Old paint scraped off, flatted and spirit wiped - supposedly ready to go. Light dusting on the bare metal and TARNATION! It reacted again - not as bad, but still a reaction.
Sometimes it's just easier to get rid of the old paint altogether. I still need to paint the wheels so I hope they're not going to do the same thing.
