Cleaning engine corrosion

My SD had sat in a dry basement for years. The engine is more crusty than dirty.I saw steves advise on simple green for dirt and grime but what about corrosion? The white slightly crusty type that aluminum tends have build up on it.Its all over the engine, in the fins and underneath.Whats the best way to go about removing it and bring back at the very least, a dull clean look?

I tired this Simple Green on a 98 cc engine, but it kept dark grey and lustreless ...

With a polish paste I had better result.

I've always used Solvol Autosol for the polished parts but any good alloy cleaning paste should work. It will even clean up the unpolished parts but you have to supply the elbow grease!

simple green is great stuff for cases [cast parts]

don;t let it dry out!!!

Yes polishes work well for polished cases to polish. Simple green isn;t a polish, it is a cleaner.
