HI70614L Pool Line General Purpose Cleaning Solution is a highly effective solution that is formulated for cleaning pH and ORP probes. Electrodes can become coated with a variety of substances when used in swimming pools, hot tubs, and spas. If the probes are not cleaned then inaccurate results can occur. Hanna's cleaning solutions eliminate impurities and residues that are left on electrode surfaces. Hanna suggests cleaning the pH and ORP probes on a regular basis to ensure that the sensor is always clean and the junction free flowing.
