Well, I don't really wear them much. I wear them to walk to yoga and I went on a trip to Cambodia recently where they were worn daily.
Yeah, Renomat and elbow grease will get it out, but the leather will be very raw and maybe some of the color gone. If you do this condition the hell out of it when you're done. It may not be worth it to try and even out the color and if you try with polish you will find the pigment in the polish will rub off onto clothes. Best to think of the denim stains as "charm".
