I had my couch professionally cleaned 8 years ago. Since then, I spot clean, vacuum, and have a washable couch cover on it 99 of the time (I have a cat and have previously fostered cats and dogsat). The cleaning sprays didn't seem to do much. I finally tried this and got this disgusting brown stuff out of my couch. Going to clean my couch again tomorrow, let it dry, and put the washable covers back on.
