I'm with Jerry:I have always had a skin head on my tenor banjo and I've never cleaned it with anything. I've changed it a few times. I use an electric hair dryer on it before wet winter gigss, or maybe just hold it in front of the fire for a while till it sounds right. The banjo's been around a lot longer than I have, and I hope it caries on for a long time after I've gone. It knows a lot of good tunes.
