A record cleaning device comprises a container body for receiving therein an adhesive material to be applied onto a surface of a record for cleaning, a slit formed in the bottom of the container body, an arm member attached to an end of the container body to be integrally formed therewith, and positioning means provided at an end of the arm member. The positioning means is located in the center of the record to be cleaned so that the container body can be rotated over the record. The cleaning device is further provided with support means situated on at least one of the bottom face of the container body and the bottom face of the arm member to form a clearance between the bottom of the slit and an upper surface of the record to be cleaned when the cleaning device is located on the record. Consequently, when the container body is turned over the record, the adhesive material can be applied uniformly onto the upper surface of the record through the slit and the clearance.
