Being a woodworker, I typically cringe at hearing everything that people put on their woodwork. If the correct finish is applied, there should be no need for a polish, and in fact, that can break down the finish. A good way (for me) to get rid of fingerprints is not put them on in the first place. Not always logical for everyone, but it works for me. Second, for the most part, a dry cloth with nothing on it should be sufficient to clean most speaker cabinets. I'm all for cleaners for electronics..at connections, or cleaning screens of cdp's that sort of thing. If you really desire putting something on your speakers cabinets, why not try some paste wax? just my 2 cents..
