If you are using a machine, VPI? 3 parts distilled water with 1 part denatured alcohol. If by hand, wash with ivory diswashing liquid and warm water(pure soap. other cleaners are intended to leave something on the dishes). Rinse well, blot with absorbent lint free cloth. Stand in dishwashing rack and let dry. If you are a secreter like me, you may want to use latex gloves to prevent finger prints. If you are washing by hand, decide ahead of time if the paper label in the middle of the record is important to you. If so you will have to devise a method that does not require emersion of the total reord in water.
If you want to give record a good scrubbing, buy vpi record brush (the one that comes with the machine and is available separately at Audio Advisor, etc.).
