As I incorporate more blues harp into my playing (with guitar and voice...), I can't help but wonder sometimes just what kind of fungi have been growing in my harp since last I played. I mean I suck pretty hard on the things (okay, okay, I can hear the jokes. Fine lets have em...), and can't help but think that I'm hauling some pretty noxious stuff into my pipes. How do you keep your harps clean? Any methods that seem to work for you? SB
