no need to unlace the wheels, i've done this a few times with no problems and perfect results.
1) use caustic soda not oven pride
2) no need to strip the hub out
3) use your sink with the caustic solution and a bowl with clean water
4) submerge the rim a section at a time in the solution until anno is removed and rinse immediately until the whole rim has been de-anno'd
5) rinse whole rim again
6) dry and polish with Mothers polish
