Can you turn the hand wheel at all? If you can, drop a little oil on the part that move. If you can't drop a little oil on the parts that should move - try to gently turn it as you oil. You can use Tri-Flo if you like - get it at a bike shop. There does seem to be a little glaze on some of the moving parts. What you don't want is the alcohol to clean things off then not enough lube and the parts that move can rust. The gear box does need some clean up, get regular grease for it. I think if you search Joe has made a lot of comments on grease.
