When my Dad passed away, this can (and I mean a metal can) of chrome polish was in a cabinet in the garage.
Anyone ever use this? As old as it is any opinion as to it being safe to use? Sometimes those older products are better. I mean look how motor oil has been cheapened up.
I clean my grill at least 1 x per yr with chrome polish, and a soft bristle toothbrush.
For old, beat-up chrome, probably won't hurt. According to the re-chrome guys, anything with 'polish' or 'cleaner' in the title has some pumice or grit which will micro scratch plated surfaces. I've used paste wax or a show shine produce for years. I use Wizard Bug Release on the bumper, grill and paint to rinse off the bugs and apply a coat of Johnson's Paste Wax.
