Thanks, Patrick. I assume "Distilled White Vinegar, 5% Acidity" is the right stuff? I guess in hindsight I'm glad my Greek salad didn't have balsamic vinaigrette. ;) Would you do the whole shoe for consistency, or just the one panel? Also, should I be concerned that they'll smell afterward, and if so how would I combat that? Thanks, I think I'll try this after the vinegar if for no other reason than to condition after all the rubbing.
