Answer

Cleaning an oral thermometer is easier than you think. All you need is soap and water.

Wash the thermometer with cool, soapy water and rinse it with clean water. Then, let it air-dry or wipe it dry with a clean cloth or paper towel. Be sure to wash the thermometer before and after each use.

You can use rubbing alcohol to clean an oral thermometer. However, it isn't necessary. If you do use alcohol, be sure to rinse off the thermometer before using it again to get rid of the alcohol taste.
