ABSTRACT:
A dusting or cleaning apparatus is mounted on the cover for the apparatus and serves to clean phonograph records on the turntable by means of a brush which is mounted on guide arms and engages the record during rotation of the turntable. The apparatus, while in engagement with the record, is guided from the outer portion of the record, radially inwardly as the phonograph record turns. This is accomplished by means of the brush which is mounted for slideable movements on the guide arms and is moved radially on the phonograph record while it is turned on the turntable.
