The effectiveness of the stick will deteriorate sooner than its six-month lifespan if it is not cleaned periodically. About once a month the stick should be submerged in a bath of 1 part distilled white vinegar and 4 parts water. Allow the stick to soak for about 30-minutes and confirm the existence of bubbles on the stick (hydrogen gas). Remove the stick and rinse thoroughly under running water. Return to use.

Air-drying the stick or removing it from service frequently can reduce its six-month lifespan due to increased oxidation. Sticks used in this manner (business travelers for instance) may need to be cleaned more often.
