STA-82 44-Watt AM/FM Stereo Receiver with Quatravox (310-2056) Care and Maintenance Faxback Doc. # 33313 CARING FOR THE STA-82 The STA-82's walnut case looks best when it is polished occasionally with lemon oil. Waxing produces a glossier finish, but can eventually cause a dull wax buildup. Clean the metal parts of the front panel and the dial face with a soft, damp cloth (do not use abrasives or solvents).
