'59 Plymouth Forum

I just replaced the grille in my SF. It came with the smooth finish grille and I changed over to the shinier "groovy" grille. Question - Does anybody have any tips on how to clean the grooves and get them shiny. Specifically in the CORNERS. I've used many kinds of polish/cleaners with a tooth brush and and cannot get the discoloration completely out of the corners. I tried a Dremel tool with a small buffer and still cannot get in the corners.

The grooved grill looks much better!! I saw the slick grille on Johnny Otter his car but it looks wrong.
I use also a toothbrush to clean them. The corners are hard but if you take all the time you have they will get clean. For me it's pretty easy cause i've done some on my grille and my grille is out. If anybody has a better option, I also want to know
