How to clean magnesium trans cases.

[DORIGTT]

Hey all,

I just picked up 3 new-to-me 914 gearboxes and want to clean them up for sale. What do I use to clean magnesium? If they were aluminum cases I'd have been done before the 'ink was dry'.

Thanks in advance.

Oh, and can they be painted? If so, what type of primer and such should I use.

I'm keeping one for myself and selling off the other two.

Thanks in advance.
