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.
Claims4
A process for removing dust and grease from the surface of a phonograph record by using a liquid composition capable of dissolving dust and grease and thereafter forming a film on the surface of said phonograph record, the steps of said process including:
- (a) applying a liquid composition to the surface of a phonograph record,
- said liquid composition including a solvent in an amount effective to dissolve grease and dust from the surface of said phonograph record,
- said liquid composition including a polyvinyl alcohol in an amount effective to form a self supporting film on said surface of said phonograph record such that said dust and grease dissolved from said surface of said phonograph record is embedded within said self supporting film,
- (b) waiting until said liquid composition forms said self supporting film on said surface of said phonograph record,
- (c) applying an adhesive band over said self supporting film such that said adhesive band extends beyond the rim of said self supporting film,
- (d) removing said adhesive band to remove said self supporting film from said surface of said phonograph record,
- whereby said dust and grease is removed from said surface of said phonograph record without brushing.
A process for removing dust and grease from the surface of a phonograph record, the steps of said process including:
- applying a liquid composition to the surface of a phonograph record for forming a self supporting film thereon,
- said liquid composition being formed from mixing 20 parts of ethanol with 20 parts of polyvinyl alcohol and 20 parts of distilled water;
- stirring said mixture;
- and adding 30 parts of ethanol, 30 parts of distilled water, and 4 parts of triethylene glycol thereto,
- removing said dust and grease from said surface of said phonograph record by stripping without brushing said self supporting film therefrom,
- whereby the surface of said phonograph record is cleaned.
