I finally got around to lapping my valves last night. Now there is a fine residue of lapping compound on the head. Its impossible to wipe it all off with a rag.

Also, there is some visible stuff on the other parts of the head. I want to get it all off so there's no problem with things grinding together.

Whats the best thing for cleaning loose oily grit off of parts such as rocker arms, valve guides, valves, pistons, camshaft, etc?

Thanks,
