Hey all, So my side window trim pieces all have some discoloration kind of like hard water stains. I have tried Bar Keepers Friend, and Barraso to clean then and make them shiny again, but these have had no affect. Has anyone had this issue or found a product that brings back the shine on these trim pieces? A pic for reference.

 

Straight vinegar could do a lot, but don't ever let it sit on painted surfaces.

 

used a buffer on mine..

buffed right off..

use heavier polish
