Oven cleaner works well for clean the cast iron rotors. Just protect the
inner bearing with 2 (cottage cheese cup-same diameter!) caps inserter in the
hole! It is what I do. Works real good. You can also coat the babbit bearing
with heavy grease and protect it that way.
I use oven cleaner lots for all kind of "deep cleaning". Just make sure you
rinse it all off when you are done.
