I got this for my mom and her old carpet, the dust mite and dog stains that never seems to want to come out. My mom cleans and brushes and tries every cleaner know in Wal-Mart. I ask her to try this one after reading a few review and research on the company. I love companies here in the USA, Carpet Miracle is a California company, got to love that. It packs a great punch and it cleans better than a bottle of bleach. I did not have to add anything to this product. It smell good, too. I received this with a heavily Discounted for a Honest review.
