I would hose it off first with a strong stream of water WITHOUT TURNING THE CRANKSHAFT! Then quickly disassemble it Dry it and then oil all the parts. Inspect the crank to see if it is bent, and if not reassemble using oil and you will be good to go.
that's the best advice posted.............but drop all the parts in a tub of acetone with a suspended basket.
take the time to take each piece out one by one and thouroughly clean, inspect and dry, placing parts on a clean towel. then light lube while reassembling. you can't be anal enough about cleanup of an engine in this condition.
