Rune (Gnomish), common (transfers to any armor, clothing, weapon, or other object that is meant to be worn or carried)
The object that bears this rune is impeccably clean and can't become soiled by nonmagical means, as it repels all mundane contaminants, such as blood, dirt, and oil. Upon hitting a target, you can instantaneously clean an object no larger than 1 cubic foot. The rune can't be used this way again until the next dawn.
