Rinse the electrode with clean water after use before putting it away and store it wet. Periodically clean the electrode thoroughly, by leaving it soaking for 10 to 15 minutes in a cleaning solution (HI 7061M).The surface of the platinum electrode must be clean and smooth. To clean the ORP electrode, rinse it briefly in turpentine, then wash it with abundant water and polish it with a light abrasive lint-free (emery) material, if necessary. The surface of the platinum electrode must not be scratched in the process and all traces of these cleaning substances must be rinsed off.
