For cleaning or finishing the exposed grout between neighboring tiles in a tiled wall or floor, the present tool has a base with an attached handle on one side and an elongated recess on the opposite sides which receives opposed clamping plates holding an abrasive pad between them which extends beyond that side of the base. The clamping plates are spring-mounted in a holder which may be reciprocated by an electric motor detachably mounted on the base or may be locked against reciprocation when the motor is detached.
