I got a red suede couch, I cleaned it bc my cat had a seizure on it and peed on accident. I got that up. I used Bissell professional, and Bissell pretreat. The pretreatment brought black stains up to the surface. I used a Bissell Carpet cleaner with an upholstery attachment. BEFORE ALL THAT I tried Gain, and distilled white vinegar and baking soda.
I just scrubbed the cushions with rubbing alcohol and a white rag. I am at my last idea, I don't know what will remove the black I brought out from my red suede couch!!
