Query: Was skeptical, but worked fantastic!

I bought a used car that looked like it had never had its fabric interior cleaned ever. I was resigned to having to buy seat covers, but wanted to give an upholstery cleaner a last shot. Bought this after reading the positive reviews and extremely impressed by it! Did exactly what the bottle said to do: spray liberally, work in with a wire brush, wipe off. And it removed 90% of the accumulated stains and dirt from the seats! I used it in combination with a Mothers wire brush and couldn't be happier with the results.
