Roger,
i happened to be in Home Depot just now and looked at an Orange Cleaner that works on masking tape glue, called Goo Gone. I mentioned it in my previous post? It specifically says NOT for use on leather. My apologies. Lexol cleaner, which i also mentioned, is made specifically for use on leather along with Lexol Leather conditioner. I know those are safe.
Apologies again!
Dave
