Have you guys heard of using Gojo hand cleaner on old radios to remove decades worth of dirt, tobacco residue, grime, and whatever else, leaving the original finish intact?

I have heard somewhere about Gojo. I'm wondering how well it might work, and if there is a downside to using it.

GooJo leaves behind a residue (probably lanolin or some other hand moisturizer) that gives the finish an oiled look. When this evaporates, the finish does not look as good. Yes, I have used it and it does remove dirt - the only problem being the temporary nature of the residue. So it must be repeated a few time a year. A more permanent fix would be to clean and then oil. Tung oil used properly is an option.
