The Spin-Clean® Record Washer MKII Standard Unit comes with everything you need to clean up to 700 records: one pair of brushes, one pair of rollers, two washable, reusable drying cloths, and one 114 ml (4 ounce) bottle of washer fluid. With the Package System, however, you get all of the above, plus an extra pair of brushes, five extra drying cloths, and an extra 909 ml (32 ounce) bottle of washer fluid, enough materials and fluid to clean up to nine times more records than with the Standard Unit at under twice the price -- our best value!
