I've done some searching but can't find much on the subject of what to use to actually clean a Dual Rectifier...interior, exterior, and the faceplate. The manual only states to not use benzene or paint thinners, but to use a soft cloth for the exterior. I bought my head used a little while ago but just haven't gotten around to polishing it up (though it sounds absolutely flawless!).
What have you guys had luck with?
