Take the residue of with a pencil eraser.... works on all trims !!!!!!!!
I use various products to shine them updependant on the requirement.
For daily use - for doing the work thing.... I use Mer Rubber and trim treatment, its about the longest lasting product I have found, and doesnt tend to streak unless you put it on to thick. Its nice and shiney, but as deep as others.
For shows, I use VRP Dressall, its got a deep luster and excellent shine but doesnt/ wont with stand the rain, it runs like a trooper no matter how I put it on.
