ABSTRACT:
The Gramophone record cleaner proposed is of the roller type having a sticky surface formed of a rubbery organopolysiloxane elastomer having a relatively low hardness and adapted to pick up dirt or dust and other contaminants from within the grooves of a record as the roller is passed over the record surface. The roller-type cleaners are superior in their easy performance of complete dirt removal in repeated operations, since the sticky surface of the roller once choked with contaminants can be cleaned simply by rinsing with water.
