Cleaning the exhaust tail pipes
Impurities combined with the effects of road grit and corrosive environmental factors may cause flash rust to form on the surface. You can restore the original shine of the exhaust tail pipe by cleaning it regularly, especially in winter and after washing.
Do not clean the exhaust tail pipes with alkaline-based cleaning agents, such as wheel cleaner.
•► Clean the exhaust tail pipes with a chrome care product tested and approved by Mercedes-Benz.
