I recently got some knobs for my Philco 650B. They were very dirty and looked like they had been stored in a shed for the last 30 years. So, I decided to clean them. I put them in the ultrasonic cleaner for thirty minutes. They came out really nice with all the grunge and dirt gone. But, they were dull. So I decided to try different polishes to see which one worked the best. All three knobs looked the same after they came out of the ultrasonic cleaner.

Here is a pic of the results.

Here is a close-up. Knobs are in the same order.

You can decide which looks better.
