You can clean anything within a five-meter bubble of you and whatever you're directly touching, immediately removing any dust, dirt/mud, oil/grease, non-water fluids, and anything else commonly considered 'filth' from the area of effect. This also extends to some things not typically thought of as filth, such as scorch marks or tarnish on metals, or tire marks on asphalt and concrete. You may choose if removed filth is absorbed by your power or simply displaced to elsewhere.
