I bought the Sonax-SmokeEx without Gorsse expectations to make my hand purchased Golf III Non smoking something friendly. Because the wash all surfaces in the interior incl. The washers did not enough, it even smelled after extensive use of orange oil clearly smoke. The amount of 500 ml in this spray bottle is sufficient for exactly a full-surface wetting of all fabrics and upholstered surfaces, the seats twice, and plastic parts such as grab bars and a reading lamp. After application, you wait a few minutes and can actually see how the product solves the smoke residue out and bring to the surface. These are easily absorbed with paper towels, ready. It is recommended that all to soak in a closed car, which I did. The money for the Sonax-SmokeEx well spent, as there is nothing covered up, but is offered a real cleaning / neutralization. Here, the Proukt gives off a pleasant scent.
