Geez: I have gone through a couple gallons of a mix (similar to what Frank uses but sans Photo Flow) in the past two months cleaning 600 or so LP's. I clean them by hand (no machine) and do not reuse the fluid. I also clean the brush with electricians alcohal between each LP and then rinse it as well as the LP. I purchase used/mint vinyl that needs a good bath and am mainly afraid of mold being spread from one LP to another through the cleaning process. If I were using a high ticket solution I would of course use less. I also need a good/cheap source for quality liners.
