The sticky cleaner comprises a dirt-collecting member that collects the organic dirt upon contact with the article surface. The dirt-collecting member has an acrylic PSA in an area that comes in contact with the article surface. The dirt-collecting member exhibits a hardness of 90 or less in the area that comes in contact with the article surface. ## Claims ### Claim 1 A sticky cleaner used for removing organic dirt deposited on an article surface, the sticky cleaner comprising a dirt-collecting member that collects the organic dirt upon contact with the article surface, wherein the dirt-collecting member has a pressure-sensitive adhesive in an area that comes in contact with the article surface, and the pressure-sensitive adhesive has a triolein absorption of 0.05 mg/mm3 or greater. ### Claim 2 (depends on 1) The sticky cleaner according to claim 1, wherein the area that comes in contact with the article surface in the dirt-collecting member has a hardness of 90 or less. ### Claim 3 (depends on 1) The sticky cleaner according to claim 1, wherein the pressure-sensitive adhesive has a thickness of 200 μm or greater. ### Claim 4 (depends on 1) The sticky cleaner according to claim 1, wherein the dirt-collecting member comprises a support member on the backside of the pressure-sensitive adhesive. ### Claim 5 (depends on 4) The sticky cleaner according to claim 4, wherein an acrylic resin is used as a material forming the support member. ### Claim 6 (depends on 1) The sticky cleaner according to claim 1, wherein the dirt-collecting member constitutes a columnar rolling member and the pressure-sensitive adhesive forms the outer circumferential face of the rolling member. ### Claim 7 (depends on 1) The sticky cleaner according to claim 1, wherein the pressure-sensitive adhesive comprises an acrylic block copolymer. ### Claim 8 (depends on 1) The sticky cleaner according to claim 1, wherein the pressure-sensitive adhesive comprises a plasticizer. ### Claim 9 A sticky cleaner used for removing organic dirt deposited on an article surface, the sticky cleaner comprising a dirt-collecting member that collects the organic dirt upon contact with the article surface, wherein the dirt-collecting member has a pressure-sensitive adhesive in an area that comes in contact with the article surface, and in the area, the dirt-collecting member exhibits a triolein absorption of 2 mg or greater per cm2 area of the pressure-sensitive adhesive. ### Claim 10 (depends on 9) The sticky cleaner according to claim 9, wherein the dirt-collecting member has a hardness of 90 or less in the area that comes in contact with the article surface. ### Claim 11 (depends on 9) The sticky cleaner according to claim 9, wherein the pressure-sensitive adhesive has a thickness of 200 μm or greater. ### Claim 12 (depends on 11) The sticky cleaner according to claim 11, wherein the pressure-sensitive adhesive comprises a plasticizer. ### Claim 13 (depends on 9) The sticky cleaner according to claim 9, wherein the dirt-collecting member comprises a support member on the backside of the pressure-sensitive adhesive. ### Claim 14 (depends on 13) The sticky cleaner according to claim 13, wherein an acrylic resin is used as a material forming the support member. ### Claim 15 (depends on 9) The sticky cleaner according to claim 9, wherein the dirt-collecting member constitutes a columnar rolling member and the pressure-sensitive adhesive forms the outer circumferential face of the rolling member. ### Claim 16 (depends on 9) The sticky cleaner according to claim 9, wherein the pressure-sensitive adhesive comprises an acrylic block copolymer. ### Claim 17 (depends on 9) The sticky cleaner according to claim 9, wherein the pressure-sensitive adhesive comprises a plasticizer.
