Now I definitely did not use this product as originally intended. I don't have a Hoover wet vacuum or carpet cleaning vacuum of any kind. I simply diluted to the strength recommended on the bottle of 3oz of cleaner per one gallon of water in a sprayer, pre-treated the area and let it set for about 10 minutes. Came back with a stiff brush and worked the cleaner into several spots that had been pretreated and blotted it up with a cotton towel. OMG I could not believe it. One year old stains that have had nearly every carpet cleaning product applied to it over the year came up with ease. I was truly amazed. I did not take a before picture as I was not expecting this product to work at all. I am just shocked out how amazing of a job this product did on those pet stains. If you have a few stubborn stains, give this product a try, you will absolutely not be disappointed.
