I have an old large Canada Dry Wink thermometer that appears to have a grayish haze over pretty much the entire front area. There is a decent amount of paint gloss remaining, but the color is more gray than I would prefer.

Is there a safe cleaning/brightening product that might help restore some of the original white color, while not damaging the thermometer itself?

Thoughts are appreciated in advance...
