Pressure-sensitive adhesive cleaner for plate surfaces

A pressure-sensitive adhesive plate surface cleaner comprising a pressure-sensitive adhesive body that has a removable pressure-sensitive adhesive, the cleaner being used so as to allow the pressure-sensitive adhesive body to contact a flat plate surface of a plate having a flat surface in order to remove organic dirt accumulated on the plate surface,

• wherein the pressure-sensitive adhesive is an acrylic pressure-sensitive adhesive comprising an acrylic polymer in which an alkyl(meth)acrylate is polymerized in an amount greater than 50% by mass in a monomer constituent of the acrylic polymer,
• the alkyl(meth)acrylate represented by the following formula:
• CH2═CR1COOR2
• wherein R1 is a hydrogen atom or a methyl group and R2 is an alkyl group having 1 to 20 carbon atoms, and
• the pressure-sensitive adhesive body has an adhesive strength of 7 N/25 mm or less to a stainless steel plate based on 180° peel test specified in JIS Z0237.
