A wet cleaning sheet 1 has a liquid retentive sheet 12 made of a fibrous material or a cellular material and impregnated with a predetermined amount of a detergent, etc., a liquid impermeable sheet 11 disposed on one side of the liquid retentive sheet 12, and a liquid gradual-releasing sheet made of a fibrous material and less air permeable than the liquid retentive sheet 12 disposed on the other side of the liquid retentive sheet 12. The liquid impermeable sheet 11 has a bag shape with openings 13 on one side thereof. The liquid retentive sheet is held in the bag and releases the detergent, etc. through the openings 13. The liquid gradual-releasing sheet has an air permeability of 0.05 to 6 m/kPa.s thereby to control the gradual release of the detergent, etc.
