P21S Polishing Soap
I have a 128i with the "factory" exhaust tips. They are not stainless steel but rather have a brushed look to them. I simply can not get all the soot off them. Has anyone used the P21S polishing soap on the factory exhaust tips? I have already tried P21S wheel cleaner on them and P21S total auto wash.
