ABSTRACT:
Dust and grease are removed from the surface of a phonograph record by applying to the surface a liquid composition containing polyvinyl alcohol and a solvent. Specifically, the composition includes polyvinyl alcohol, ethanol, distilled water, and triethylene glycol. The applied composition forms a self supporting film upon drying. Thereafter, the film is stripped from the surface.
