Just thought i'd share my success with the method explained in the video below -->
It worked to bring back the shine and removed much, if not all, of the surface gunk. Of course it did nothing to help the pitting or the chrome fog on larger pieces but on smaller chrome items that you see and interact with everyday
(interior bits, door handles, etc) this method worked great! See the side by side of my side mirror adjustment plates below -->
That's great! I am definitely going to try this on mine.
