I lived in the Midwest at the time and with forced air heat, our place was very dry in the winter with lots of static electricity. Everything would be attracted to and stick to my records. The Zerostat did help.
Just found one of these. Including the instructions. Never used. Dumped the fluid. Oh yeah, wore out a couple of these and a Zerostat Gun back in the day. Discwasher didn't get worn out but probably gummed up with the THC from profuse consumption.
