Probe cleaning and correctly storing pH probes ensures you get the most accurate readings possible and will maximize the life of a probe.
 
The probe surface is where the instrument takes the reading of the solution or soil/media. If the probe face is dirty or contaminated, the readings may be inaccurate. Much like the windshield of a car, if it’s dirty you can’t see out! If the probe face is dirty, it cannot read the solution or soil accurately.
