Printed for reference. I really appreciate your detailed explanation of this process. My Clean Sweep record brush arrived yesterday so I can follow this process exactly as you described. I tested our RO water last night and it's at 11 TDS ppm. The distilled water I bought tested at 0 TDS ppm. I really wonder if there is any significant difference between using the RO water and the distilled. Out of curiosity, what enhancements do you suggest? Thanks.
