How to Sanitize a Second Hand Recorder Instrument

Updated February 21, 2017

Many elementary school music teachers use recorders to teach students about various musical concepts such as pitch, rhythm and breath control. Sometimes teachers must reuse recorders if the students do not buy their own instruments and the school cannot finance instruments for each child. In these instances, it is very important to sanitise the recorders in order to prevent the spread of illness. You also may need to implement this sterilisation process if you buy a second-hand recorder for yourself.

Mix together 56.7gr of sterisol germicide and 4 cups of cold water. Sterisol germicide is a commonly used substance for sterilising musical instruments, as well as other objects possessing mouthpieces such as scuba equipment. Mix the solution in a container that is not metal.

Immerse the recorder in the solution for one minute.

Remove the recorder and shake the excess liquid out of it.

Rinse the recorder under running water, although this step isn't necessary.

Allow the recorder to air dry for several minutes before using it, or wipe it off with a paper towel. You may want to disassemble the recorder first if you plan to wipe it off.


You can keep the sanitising mixture in a covered container and reuse it for up to a week, after which you should discard it and mix a new solution.
