Back in September 2010 one of my friends left chocolate milk in my car and I had no idea that she had left it in my back seat. The milk then exploded when I went to class and had to park in the sun. I took it to a car wash where I knew a friend and they cleaned the seat and scrubbed it, but it still did not solve my problem. I also tried to use a mini Bissell carpet cleaner. It worked and got a bunch of the milk out, but I still smelt the spoiled milk. As time went on the smell kind of went away, but now that it's April and it's starting to get warm again the smell is slowly starting to appear again. I can't afford to get it detailed because I am a college student with no money. I'm not at all sure what to do now that the stain has been there for awhile. Please help me figure out what to do. I can't buy a new car so please don't suggest that.
