Dust repellant

In 1972, one of the Apollo astronauts got the first sniff of lunar soil. Of course this wasn't while working on the surface as he was in a sealed suit; it was inside the Lunar Module with the suit off. Apparently, it smelt a bit like gunpowder.

Fine dust such as that found on the Moon or Mars may leave burn marks on the skin and potentially cause health problems for future manned missions. So, NASA are about to start funding Project Dust. The project will study thin-film coatings that repel dust from tools and other surfaces, and electrostatic techniques for shaking or otherwise removing dust from spacesuits. Perhaps the dust repelling book jacket from Back to the Future II isn't too far away.
