This product is a miracle in a bottle!!! We have tried so many carpet cleaners over the years and nothing has even come close!!! I wish I could give you a BIG hug!!! I am so grateful to have found this product! It not only returned our carpet to the color it's supposed to be but there is absolutely no smell at all!!! I am AMAZED!!! It even took away a random stain that we have been trying to get rid of since we moved into our house 6 years ago! Thank you soooo much!!!!
