My new carpet cleaner with this solution is amazing. I have a small home and carpeting only in the 2 small bedrooms......and most professional companies want an arm and a leg to clean the 2 rooms. The cleaner and this solution really work. The newer carpet in my bedroom looks brand new again. The 20+ year old carpet in my teenager's room looks fresh, and while a bit worn, looks so much better. I am also very sensitive to perfumes and fragrances (they trigger migraines) and this solution is perfect......just a light, fresh clean smell.
