BISSELL Pet Pretreat + Sanitize Stain & Odor Remover, 1129

How oxygen cleaners work Oxygen-based stain remover works quickly to remove a variety of stain types, making it a great go-to stain remover to have on hand. Oxygen-based sprays work especially well on stains that have lots of color, like coffee or juice. The reason oxygen-based cleaners work so quickly is that oxygen is a very active molecule. As soon as the spray is released from the bottle, the oxygen molecules begin quickly "eating" the stain away. Oxygen-based cleaners are done working within a couple of hours, so you'll see the stain beginning to fade relatively quickly. For best results, get the stain matter as thin as possible prior to treating it with the oxygen-based cleaner. You can do this by removing as much from the surface as possible and by extracting some of the matter out with an upright or portable deep cleaner.
