Here are the results of my test....
The Campy hub I soaked is cracked and the only reason I have it is to eventually use the remaining bearing cup. I soaked the drive side, without the cup, in OA for 24 hours.
Those little pits were caused by the OA, though the hub wasn't perfect before it went in the solution.
As it looked coming out of the solution:
As it looked after washing:
As it looked after a brief polishing with Blue Magic. Note the nice crack visible in this picture:
I tried to watch the etching progress, and there was very little etching after only a few hours in the solution which was pretty strong. If I soaked the whole wheel, I would definitely watch it closely and take it out as soon as possible.
I also put a spoke nipple in for a couple of days with no apparent harm done.
