Cleaning jobs remove blood, ichor, vomit[Verify], stagnant water (removed from aquariums or spilled from dropped buckets), and rubble (from used bolts and ammunition) from the floor and walls of your fortress. Cleaning will not move corpses, body parts, or dead vermin; those tasks require the refuse hauling labor. Cleaning has no effect on miasma, which will naturally dissipate over time.
A dwarf who decides to clean will stand on the space to be cleaned for a moment, and that tile and all adjacent tiles will be cleaned.
While cleaning must be activated in the labor preferences, it does not raise any skill, nor does cleaning rely on any skill to determine the speed or effectiveness with which it is done.
