A cleaning sheet has a first direction, a second direction, and a thickness direction that are orthogonal to each other. The cleaning sheet includes: a water retention sheet that retains a chemical solution; a surface sheet that is a nonwoven fabric; and a cleaning region. The surface sheet includes: a first surface on a side of a surface to be cleaned; and a second surface on a side of the water retention sheet. The surface sheet includes, in the cleaning region, a plurality of flap portions. Each of the plurality of flap portions includes: one end; another end; a fixed end portion that connects the one end and the another end; and a free end portion that protrudes from the one end and the another end as starting points toward a direction away from the fixed end portion.

A cleaning tool has a rotating section including: the pressing section including a rotation-control protrusion; a first coupling section; and a second coupling section. The second coupling section includes a plurality of rotation-control recessions that include: a base section that receives a sliding section; and a rotation-control wall section that fixes the arm angle by mating with a side surface section. The second coupling section also includes release-direction inclined sections whereby, in the housed state, the rotation-control protrusion can be moved from a first rotation-control recession to a second rotation-control recession, by the second coupling section sliding the sliding section to the first rotation-control wall section mated with the rotation-control protrusion, without pressing the pressing section.
