The important thing is CLEAN not what you use except that cold cleners will not remove many things like glass beads completely
After all the bruch cleaning I use clean hot water
and soap.... air presser...followed by WD40
Go get lotssa clean rags use em
I've never NEVER seen rusty fingerprints...Sorry that's just strange!
Don't forget to use a clean garbage bag to wrap clean things individually in
I use white grease to lube bearings but you might want something like HRL
Just don't get it everywhere...motor or your face
