Why are the readings from my ORP sensor noisy?

Residue on the tip of an ORP electrode can cause the readings to be noisy. To clean the electrode, use a soft cloth to wipe a small amount of ethyl alcohol or isopropyl alcohol around the globe-shaped tip of the probe. Rinse the tip with distilled water, and repeat the alcohol cleaning one more time.
