It looks like some of the chrome is worn off.
Polishing usually does not help remove pitting, but it can help make it less obvious, but only use a proper chrome polish and nothing more aggressive.
I'd like to see them in person before you do anything else to them... I will try to get out to the Corona Cars & Coffee on the 23rd if you think you can make it. Text me at 714-580-3572 about meeting up.
