A brush, or mop, or like tool (1) has a handle (5) and a head (7). The handle (5) is able to carry a liquid that can be dispensed therefrom during use of the tool (1). The handle (5) has a liquid dispensing passage (51) through which the liquid can pass to an outlet (17). The passage (51) has a valve (19) to control the passage of the liquid and the valve (19) has a sliding gate part (65) and a stationary gate part (49). The sliding gate part (65) can be positionable to block the flow of liquid in one position, and to permit the flow of liquid in another position. The sliding gate part (65) effects a sliding wiping cleaning of the valve (19), and therefore minimize clogging of the valve (19).
