if you want it to look even shinier still, after you've finished with the scouring pad (or scotchbrite, but i find green saucepan scourers are better, they make a finer cut) you can do the same thing again with a rag and some cream cut and polish (its an abraisive polish meant for cars), it makes the scoring MUCH finer. I've restored a few 70's atari fire buttons (among other things) using scourers and cut and polish, they come up like new.
