I was in a hurry when I wrote my last response, so I'll clarify. The ammonia does a great job of shining up the chrome. The wheel cleaner is better for CLEANING the chrome if it's really dirty. Rinse with water. I also use this for the pushbuttons, remembering that I disassemble the radio and clean up the tuner in the sink. You can carefully clean the buttons on the set, using a toothbrush, and if you really need to clean them you can remove them from the radio -- except the on-off switch. The others you can unscrew -- long shaft but you can do it. Other cleaners may work, but the ammonia and wheel cleaner are what I use. Toothbrush is great for all the crevices. Bleche-Wite does a good job of cleaning plastic -- knobs, buttons, dial glass, etc. Two cautions -- first, be careful when cleaning the inside of the dial glass, as it will melt the white paint from the markings. This is actually good if you want to restore the dial. Clean with Bleche-Wite and a toothbrush, rinse, repeat as needed. For the Conelrad marks at 640 and 1240, I use Testors Fluorescent red paint. Wipe off the excess immediately with your finger. Let dry. Then I use acrylic white paint for the numbers -- again, wipe off the excess. Let it dry completely, then polish the plastic which will clean off the excess paint. Use either Novus scratch remover or Simichrome -- both work well. Follow up with Novus fine. Now for the other caution: Bleche-Wite is great for all these plastics, Delco, Ford, you name it -- EXCEPT Studebaker. I know we're talking Thunderbirds here, but letting you know, Studebaker plastics and Bleche-Wite don't mix. Use Windex instead -- REAL Windex, not other brands -- they can be bad too. Novus polish is fine on these.
Again, let me know if you have questions.
