I had been getting a lot of static build up in my burr grinder, to the point of discouraging me from grinding beans. The grounds were stuck all to the cup, and smacking the bottom only resulted in grinds all over the counter. I came across a video that showed a method to take a paper towel, dampen with water, and squeeze to add a couple of drops of water to the beans prior to grinding. I thought for sure that this would result in a muddy mess in my grinder, but to my surprise, it worked! No more static, the grounds are dumped very clean from the bin into the container that I keep them in. Just wanted to share. I'll see if I can find the video again and link to it. Hope it helps someone.
