I've used a Zerostat for the last 30 years or so. They are easy to use and very effective. If you are thinking of buying a used one, be aware that they do wear out. If there's no "snap, crackle, pop" when you quickly pull the trigger and release it, then the Zerostat is worn out. I've worn out three, and my fourth is getting there.

I do not own a record cleaning machine yet. But i do plan to get one. I dry brush them with a carbon fibre brush for the moment before a playing. I do notice when lifting a record I have played off the turntable platter I get static electricity. Does anyone have experience with a Zerostat and does it work?
