Akai GXC 709D Cassette deck, cleaned and new belts

Here is a Akai GXC 709D cassette decks. It does play, FF, REW and REC. I stopped there because the buttons, PLAY, FF, REW, REC, PAUSE AND STOP. All have tarnish that I can not get off and either need replaced, painted or if you dont mind the look left as is.
