My wife recently purchased Bac-Out Stain & Odor Eliminator. We have an old dog that has a hard time controlling some bodily functions and seem to be needing to spot clean the carpet more and more. We have tried many other products including Simple Green and nothing including products specifically for carpets worked as well as this. Also does the best job of eliminating the odors left behind. The label says it has Live Enzyme Cultures & Lime Peel Extract. Whatever it has it works!
