Trying to restore what looks like could be a serviceable oxblood/black saddle shoe. The oxblood almost looks like it had been polished with black, and I'm trying my best to uncover what's underneath. Per a recommendation on this board, I've been using Lexal (ph) on these puppies. Is there any chance I'll be able to restore these to what the circled part of the picture below suggests is the original color? Can anyone suggest a better way?
