Fortunately, somebody does care. The folks at Microphome have just what you and your band needs to keep from contracting the next deadly thing (well, at least it might make those stupid germs think twice about who they're foolin' with). Professional Mic Cleaning Foam. Don't leave home without. They claim it kills 99.9% of germs on the stuff it touches.
Check-out the product at www.microphome.com -or- www.microphome.org (which in this case I'm thinkin' they mean organism).
It's just like spraying shaving cream on your favorite '58, but it's hittin' the gross stuff head-on.
