One of the things in my grandfather's old footlocker was a WWI-era brown leather holster for a 1911. It's in decent shape for being as old as it is, but it is dry and pressed in from having a lot of stuff piled on it for so many years. I want to use it as a holster for my Kimber, and I'm looking for ways I can clean it and make it soft again. I was thinking a little saddle soap and some Neet's foot oil. Suggestions?
