I stupidly wore my tan Coach out to a bar a few months ago and someone spilled a drink on it. Anyway I have the Coach leather cleaner and the stain did not come out. Is there anything else I can try? The bag is all leather. I was thinking about buying leather stain slightly darker than the bag and staining it so it'd all be the same color. Is that really stupid? I don't want to ruin the bag but I don't want to carry it with a huge stain either.
