Yes, brasso is recommended.
If they are white and full of dirt and crud (which in fact is a mix of human skin and the crud it had been touching!), I use Vanish, which is an English detergent used to whiten/remove stains from clothing in washing machines. Use a teaspoonful in a cupful of water and stir, leave for two or three minutes and the filth comes off easily. Here, I realise that Philco knobs are generally Brown!
I have also read of Ammonia being used, but I most certainly would not recommend it.
One O'clock here, so I'll retire now. This is a great site for the radio enthusiast!
