These should be familiar to audiophiles, as they were (and I suppose still are) used to remove dust from LPs. As I recall, there were simple handheld devices that used a piezoelectric crystal to produce a discharge; other devices used small amounts of an alpha emitter like polonium or americium.

Spudis put an intriguing blog post on The Deadly Dust of the Moon | The Once and Future MoonHere’s a quick excerptThis so-called “nanophase iron” (from its extremely small size) makes the dust easily attracted to a simple magnet. A brush made with magnetic bristles will clean surfaces of most of the dust. Incidentally, this same property permits … The Surveyor 3 spacecraft, exposed on the lunar surface for over 30 months before examination by the Apollo 12 crew, was not covered by any significant amount of dust, other than that thrown up by the nearby landing of the Lunar Module. … [...] [...] Dr. Paul D.

I just don't think it's the serious problem that it's often portrayed. And many thanks for coming to my public lecture at the LPI last night! Great! I have no doubt that the dust can be handled.

We are doing experiments to ensure that lunar dust is not an obstacle but a resource for lunar missions. Dr. Spudis: Thanks for giving the talk at Lunar & Planetary Institute last night.
