These 10" LPs are not the typical softer vinyl we know but the stiffer, less yielding vinylite. The LPs are remarkably unworn except for the solvent use. Steam cleaning and brushing may be in order after the various VPI cleanings. My friend suggested pure mineral spirits added to water and fotoflo. Thanks for your suggestions.
