Oven Cleaner may eat at bearing surfaces, as well as aluminum.  I recall
hearing/reading this.

Correct - the warning label on the product warns against using the cleaner
on aluminum (and a host of other surfaces). I did my application in two
short steps - I let the cleaner stay on the rotor ~ 10 minutes, scraped
gunk, flushed with water and repeated. The directions for an "oven" was
leave the stuff on anywhere from 20 minutes to overnight. My short,
repetitive method worked quite well.

I planned on replacing all my bearings, so I didn't protect them.
Interestingly, they showed no change after having the gunk sitting on them a
couple times.

I tried Easy Off oven cleaner this morning. This is the results of two 30 minute
applications
with nylon brushing. Kind of caustic to work with and it must be done in a well 
ventilated place. You do need long rubber gloves because it is death on bare skin.

I still prefer glass bead blasting. I came up with a minor improvement in the
glass bead blasting process. I will make a couple of metal cover plates to keep 
the glass beads out of the bearing and gear area of the rotor. Will help when 
I clean the glass beads off.
