:iagree:
Although I don't see the hype everyone is giving folex. I bought some, it worked ok. I gave mine away. I now use prochem liquid slurry, cheaper and works waaaay better. I've had stubborn stains like the OP, and tried APC, Folex, Laundry soap with oxyclean without getting the stain out. I tried those products with an extractor first, then steam after. I had gotten a sample of the prochem from a local cleaner and tried it and it took out 80% the first pass, the rest on the second pass. If you still haven't gotten out the stains(if its your personal vehicle) try the prochem stuff.
