Lug Nuts & Calipers starting to rust


I wash my car regularly and I have strong signs of rust showing on all my calipers, maybe using wheel cleaner sprays caused the coating to wear off and allow the rusting to start. Nevertheless this appears to be a quality issue so I brought the car to my MB Dealer and they had a factory rep look at it. I wanted them to replace the calipers but they are going to remove the rust from the calipers and re-coat them and replace the lug nuts which are supposed to be galvanized all under warranty.


If you have a blower and no dust/dirt around the car, that works pretty well also but nothing compare to putting it on the road for a mile or two. I use to live close to the interstate and instead of drying, would drive about 100mph for about 2 miles between exits and that would do an amazing job of drying the entire car...only problems there are the cops and the bugs...

Sorry, thats the lug nuts that will get replaced under warranty, your brake rotors may have surface rust from water sitting on them for a day or so but as soon as you brake it comes right off its just on the surface. No worries.

I know you will argue this point so before you do, research the subject.
One cleaner to avoid is Simple Green. Leave it on too long and the paint will be damaged. Personal experience.
