If anyone can answer this question I would sure be thankful!!
I have recently tried throwing directly on the wheelhead without any
bats. The clay seems to stick much better and I can remove the
pieces from the wheelhead so much easier than the plastic, plaster,
wood, plywood, birch, particle laminated or any other bat I have
tried.
Here is my problem.
I left an aliminum throwing rib (not stainless steel!!) on the
wheelhead overnight. When I returned in the morning there was a
patch of blackened aluminum the same shape and size of the rib on the
wheelhead. It took close to twenty minutes using the mildest
cleanser I could find to finally get all the black off.
What is happening? Will I have to give up using aluminum tools when
working with my aluminum wheelhead?

It wasn't the aluminum rib that did it, per se; it
was the moisture that was trapped between the rib and
the wheelhead. (You'll also notice a blackish color
when you scrape slip off an aluminum wheelhead.)
Use any tools you like. Just don't leave wet stuff
on the wheelhead!

I am pretty certain that the stain is harmless

Don't know if this will clean your wheel head, but the best thing I have
found for cleaning aluminum oxide on aluminum itself is isopropyl alcohol
(plain old rubbing alcohol). I should think it would take the oxide off
just about anything else, too.
Got that from "Ask Heloise".
