Abstract
A cleaning tool (10) includes a cleaning head (11) and a handle (12) and is to be used with a cleaning sheet attached to the cleaning head (11). The cleaning head (11) has a gradual-liquid-release mechanism (16) including a liquid reservoir (14) and a gradual-liquid-release portion (15) that, by the action of hydrostatic pressure from above, gradually releases a liquid agent supplied to the liquid reservoir (14) to a cleaning face (17a) provided by a cleaning cushion (17) of the cleaning head (11) while causing the liquid agent to pass through a multitude of fine flow paths. The gradual-liquid-release portion (15) is provided continuously across substantially the entire width in the length direction of the substantially rectangular cleaning head (11) as viewed along the short-side direction of the cleaning head (11), the portion (15) provided facing the cleaning face (17a) of the cleaning head (11).
