Unfortunately I did not have particularly good experience with the product. I bought a two-year used vehicle and then wanted to clean the cockpit. When selecting the cleaner it seemed to me essentially on the "matt effect". For most plastic parts in the cockpit (SEAT Freetrack) is black and brown hard plastic without Unterschäumung. The cockpit was previously washed away from me with clear water and then dried with a towel. Then I have the Sonax Spray distributed with a cotton cloth on the plastic and again wiped dry. Unfortunately, the dosing pump works very poorly and it drips after each spray from the nozzle. Worse, however, is the lack of cleaning effect and the subsequent filming. I then had to wipe again with a wet sponge. A few days later I ordered from Amazon Meguiars Quik Detailer the Interior Interior Shampoo and lo and behold, the microfiber cloth is taken in conjunction with the cleaning of all dirt from the cockpit. Only now it looks like new.
