Hey guys, anyone here with Tricker's shoes in their Acorn Antique calf leather? I bought a pair of Bourton Brogues a couple of weeks ago and promptly spilled coffee on them. There is now a discoloration right on top of my left foot (looks like a dark circle surrounded by a lighter colored ring) and you can see that in the photo I attached here. I have been periodically wiping the spot down with a damp cloth but haven't had much luck yet. I'm starting to wonder if I should try some Saphir Renovateur but don't want to do anything that may cause any more issues! Any ideas?
