How to Clean Thermocouple on Hot Water Heater

There are a number of ways how to clean thermocouple on hot water heater but not all are equally effective. One of the best ways is to use a chemical stripper and then dip the strip into the chemical stripper and rub gently to remove all the contaminants like mineral deposits, algae, mold etc. If you have to clean thermocouple on a continuous basis then it is recommended to do so using only water to avoid discoloring the heating element. Another thing that can affect the working efficiency of a thermocouple is buildup of carbon dust on its contacts. Hence, to prevent this you can periodically clean your heating system using a vacuum cleaner.
