What to use to remove brown spots on plastic chrome trims caused by Mag Chloride?
I am in the rocky mtn area and the city uses meg chloride on the roads to melt snow in the winter and cause small brown spots on the X5 chrome trims such as front grills and rear BMW badge chrome housing. I tried P21 chrome cleaner paste but it did not work. Does anyone has any luck with other products to remove those brown spots?
