What is the right blasting material to use for ally engines?

Has your Voskhod broke again? Suffering dodgy Italian electrics? Post your tales of woe here. Or ask odd questions about the rear wheel spacer on a Vincent Black Widow, should it take your fancy.

Long story but my car was really coked up and the dealer used walnut shell blasting to remove the crap.

I gather that it's an accepted blasting material that has a certain hardness, but it disintegrates after use

In the Royal Australian Air Force the prefered medium for cleaning critical components was Sugar as it dissolves completely when given a hot wash afterwards,Biggest trap is making sure any engine parts are scrupulously cleaned afterwards especially if glass bead was the cleaning medium hence the use of sugar.
