Have a 17 years allten DB combi. After the car valeting wanted almost 200 euros for cleaning the inside, I decided to order this product, and to do it yourself. Have on Saturday in 4 hrs., The internal cleaning itself does. When I came to the cushions where now there were several stains on the cushions with two small dogs, doubting me. Well've the upholstery cleaner, the cleaner had sprayed leave on shortly and wipe with a lint-free cloth. Could not believe what I saw then, the stains were all gone. Time spent on the upholstery cleaning 10 min. and everything was tip top saber. Can only recommend this cleaner. Top
