Can highly recommend this product. In my case it was applied on dark fabric, which was not cleaned for several years. Sprayed the product is slightly foam-like, after this immediately into the tissue. With a smooth sponge or cloth man then rub a few times over the Gewebsfläche and allowed to dry the fabric. If you still remain residues, the application is repeated. The result speaks for itself. Super-fast cleaning, which is done in a few minutes. The Gewebsstoff my sofas looks bought as new and also the odor that the detergent is leaving pleasant. After about one hour drying time in ventilated room, the cleaning agent is completely dry.
