I have a M by MJ yam colored bag that I've managed to get really dirty and stained. I took it to my dry-cleaners, whose leather cleaners didn't get it clean. I'm not even sure if they tried, the owner wasn't there today, and the bag looked the same to me. So, I was wondering if anyone know of a good leather cleaner in NYC or should I send it to Lovin My Bag, I've read great things about them on this forum. Or should I attemp this myself and what would be a good product? TIA for your help.
