In most situations, hot water with a mild liquid detergent is an effective cleanser.
Acetone easily cleans most organic matter, and hypochlorous solutions will remove algae,bacteria, or molds.
To prevent cell damage, abrasives or sharp objects should not be used to clean an electrode.
A cotton swab also works well for cleaning.
