|One end of the wire is stuck into the rubber mat about 4 inches while the other is soldered to an alligator clip which is then attached to a grounded nail.|
I looked through various pages of advice on the internet and one suggested grounding the mats. I did this with a piece of 14-gauge solid wire stuck into the side of the mat. An alligator clip on the other end allowed me to attach the wire to one of the nails I shot into the concrete to secure the benchwork. This actually helped the situation but did not reduce it to levels I thought were acceptable. More research was done and I found an industrial static reducing spray, Staticide ACL 2001. I ordered a gallon of it, sprayed it on the matting with a garden sprayer and let it dry. It worked! The static electricity was gone.
At the same time that I was applying the anti-static spray, I replaced the matting in my humidifier on the furnace. It hadn't been done in a couple of years. Right away, the humidity jumped up significantly which will also help the static problem during the winter. When I lived in Southern California, humidity, or lack thereof, was never a problem so this is rather new to me. The perils of living in the midwest, I guess. At least now I won't be blowing decoders during an op session.
