I can't comment on the general usefulness of this idea, but the coffee
itself will leave a microscopic oily finish. I notice this when I wipe
out our coffee pot.



Hey, the other day, when I first went over to Bldg 1, I discovered a
Terrible Site - the inside of my coffee mug. Those crazies have a really

coffee mug, "Yech! What is that stuff?? Quick, add coffee and cover it
