Good morning....I have a computer/dial that has indented numbers...trouble is
they are filthy..Have tried dawn, no luck. Got a q-tip and gas,,no luck...Does
anyone know what works to clean the numbers???< thanks Warren

I think you are on the right track. Just keep moving toward more harsh chemicals. Maybe a pre-wax cleaner and then paint thinner and last but not least acetone. Bear in mind that you will probably start removing paint. Just proceed with caution. Acetone will definitely strip the paint off. Be very careful. Your best bet will probably be a pre-wax cleaner and your q-tip. Good luck.

Oven cleaner..

Thanks for the input from both of you...will give it a try/./.Warren
