I bought this when I was pregnant along with a steam cleaner instead of renting one. I used this detergent because it'd been a while since we had the carpets cleaned. It worked overtime so I didn't have to. It removed old dirt by our entrances better than I could've expected and left our carpets soft and fluffy.
I purchased this for use with my carpet cleaner and I was not that impressed. It worked very well on the sections of the carpet that were not that bad. However, I had some mud and coffee stains that I went over 3 times and could still see remnants of the spots.
I would like to see this product to be more of a deep cleaning, rather than on the surface.. My carpets always look nice until the are completely dry, once dry the deep dirt and grim comes back to the surface..
