摘要： A method of conditioning a phonograph record comprises applying a very thin film thereto of a quaternary ammonium salt having at least one long hydrocarbon chain. Preferred compositions have the formula
wherein R 1 is a hydrocarbon radical having from 8 to 22 carbon atoms, R 2 is a hydrocarbon radical having 8 to 22 carbons, C 1 -C 4 alkyl, quaternary ammonium alkylene, or benzyl, and R 3 and R 4 are C 1 -C 4 alkyl or -(CH 2 CH 2 0) n H, wherein n is an integer from 1 to 20, and X is a watersoluble salt-forming anion. The compound is applied by spraying small quantities of a solution containing a minor amount of the salt dissolved in a solvent on a soft applicator, and pressing the applicator against the record while the surface is moving relative to the applicator
