That's okay Dora. WTF describes it quite well. It happened in church actually...LOL We have a laid back service on Saturdays and they serve Cappachinos and flavored Coffees. Mom (I thought had finished hers) so since she has arthritis I picked up the cup by the handles (It had a lid) and also my Bombay Satchel. I thought the cup was empty and by the time we got to the car realized it sloshed all down the side of the bag. So then I tried to clean it myself (Bad move) then I tried to use saddle soap on it...(worse move). It was trashed. So off it went and I don't know technically what Barb did but it came back free of coffee stains and smells and the bag looked new.
It can be expensive if you only buy a bag for 200 or so but on a new higher priced bag, it can be worth it. I hear she does amazing things to Balenciagas and redyes them, fixed tears and piping wear.
