Can dust collect on items in space like they do on Earth? Would an old abandoned section of a space station have soot covered walls?

Answer 1

there are tiny particles in space and do collide with orbiting objects these suffer from orbital drag as the impacts and the tiny amount of atmosphere slow them down. This means that unless orbiting objects are fairly regularly boosted into a higher object they will fall back down to Earth, so before they can get “soot covered” they will be crashing back down to Earth.
