I was shocked at how well this stuff worked! A friend recommended it to clean up a spill on the brand new carpet in my apartment. I thought it was worth a shot. It worked so well on the carpet that I thought I'd try to clean up my car with it a little bit. There was a stain on my upholstery that didn't come out when I had the car professionally detailed. I sprayed the Oxy Deep on it and let it sit for a few minutes while I cleaned some junk out of the car. When I came back, the stain was gone. I hadn't even wiped it down, scrubbed, nothing! It was just gone. I am thrilled.
