For all my parts that go in the crankcase, tranny, or bearings/bushings, I usually use some premix gas to clean those parts. I take a clean oil pan and put some premix in it and then put the parts in there to soak. I use a brush to scrub away the old oil and residue off of the parts. Then use rags to dry them off. That way you know they won't rust because they will have a thin layer of oil on them already. I had a crank sitting on the shop floor for a month and not one speckle of rust and I live in the midwest where it is humid. Don't put seals in the gas though. That will dry them out and make them crack. Just a thought.

 

Carb cleaner and contact cleaner work just fine to clean but will leave your parts dry and can rust.

i alway's hit it with some brake cleaner and blow it off with the air hose then hit it with some wd-40.i have hit some really nasty cranks with the power washer then blow them off with some air....no dirty minds please.....lol

i vote for gas, premixed or straight.

 

it's a great solvent, it's a hell of alot cheaper than carb cleaner and everyone has some laying around the shop so you dont have to drive to get it...
