Can the Battery Operated Toothbrush be sterilized?
No. Wash the brush part thoroughly in running water after each use, and dry it completely. If there is any particularly troublesome dirt on the brush, replace the brush with a new one. If the main unit becomes dirty, soak a cloth in either water or a mild detergent solution, wring it out, and use it to wipe the dirt away. Then wipe the unit again with a dry cloth. Allowing water to get inside the unit may lead to mechanical problems or unforeseen accidents, so check to see that the lid of the battery compartment is tightly closed before you do any cleaning or maintenance.
