Hello together, today I tried it for a long time with rim cleaner, bath cleaner, chrome cleaner and polish to get my rims clean. But unfortunately without much success. That with the 1 shows the rim before cleaning, the 2 after cleaning. What can I do there. That bothers me immensely that the car top is clean, but the rims rot. As much as I know these rims would be used as winter wheels, ….. I still have the steel wheels with the original wheel caps.
