I think your girl friend is related to my wife. She would say the same thing. Pickle juice..hmmmmmm/ I would try the spot shot first that was suggested if you can find it. If not, try a soft solution of dish soap, make sure you delute it with lots of water. Don't use too much so it soaks into the back cushion, you will never suck up behind it. Use a soft brissle brush along with it. allow to dry. OH, don't just clean the one area, to the entire seat so it blends in. and like everyone else says, she's out a here. What I did was put a loud exhaust on my car so my wife doesn't want to get in it.
