LOL... I had one of those guns too. When I first saw one I was pretty skeptical but as you know they really do work as an antistatic device.

I also remember a wet cleaner called Lenco... it actually made the vinyl wet using a small, hollow tube like tonearm and brush as it played lifting dirt out of the grooves and allowing the stylus to track better. It did work but with a price.. if you used it once you had to keep on using it because when it dried the lifted dirt crusted back onto the surface of the record with even more tenacity than before you used it. The only way to lift it back up was to rewet the surface.

I hated the Lenco cleaner.
