Amazing product and wonderful customer service. I'm a rescue volunteer and have fostered over 30 dogs plus have 4 of my own. I clean my carpets about once a month but was frustrated and disgusted with the stains that were not coming out with other products (I've tried so many other products many of them being more expensive than this one). We were to the point that we were considering ripping out the carpet and just having a concrete floor. I saw this product mentioned in a FB group so after reading some of the reviews decided to order it. I used as instructed in my Bissell Pro Heat and was extremely happy to see my light beige carpet again without the ugly stains! It has not looked this good in years! I just placed my second order.
