Moin, you’ve been reading a lot lately about a washing method called Optimum No Rinse. It’s been refined, in which the ONR comes into a bucket, which is then filled with water, in which a lot of microfiber cloths are then inserted. With these, “quasi as disposable cloth” is always washed only a small part of the car and then dried directly. For people who do not use the laundry on the street, or no SB box is nearby, that seems to be a good idea. ine good method to be – after all better than washing system. The whole becomes possible, because the ONR “closes the dirt particles” so that no scratches should arise. In the last statement I am somewhat skeptical or suspect a large part of marketing. By what should the dirt be enclosed? And above all – can not such something also simply with normal shampoo work the same way ? It is only about that a sliding film arises, so that the dust / dirt not directly So – what do you think – should / could ONR also work with normal shampoo solution ? PS – before someone writes: “Try it …” , let’s say that the thread should first follow a theoretical approach / exchange Gruss E
