There are two types of faceplates and three types of knobs.
Be careful on the faceplates, the brass type will scratch easily.On the aluminum plate sometimes water or cleaners will melt away the lettering so be careful.
Brown plastic knobs- soak in 409 to remove knob fungus.
Machined aluminum knobs - toothpaste works great as Geek mentioned.
Plated pot metal knobs - toothpaste again to clean. Polishing these ain't gonna help any, what you see is what you get.
