The rust remover advertised on this web site works well, and does not seem to harm aluminum, but CAUTION it seems that it destroys pot metal!

I bought a gallon of that rust remover, and first soaked the tuning gang, light, and tube shields from my rusty Philco 620.

Here is the tuner from my Philco 620 after initial cleaning using Naval Jelly carefully on the chassis, trying to avoid the aluminum - note the dial mount on the far end:

Here it is after using the Miss Belvedere solution and a little brushing with plastic and brass brushes
