Eis, you should know that windex contains ammonia which is a good cleaner but will also turn tannic woods black. If your stock has any bare wood unprotected by old finish you could end up with a dark spot. I like the turps/mineral spirits route, they will loosen most undesirable stuff but won't do harm to wood or dry finish. I would also stay away from water and water based cleaning unless the original finish has no breaks in it.
