Cleaning the Instrument Exterior
When cleaning the instrument exterior, do not use alcohol, disinfectants, or solvents, or any substance that
contains these ingredients as they can damage the gas sensors and otherwise compromise instrument
integrity.
For typical dirt and grime, wipe down the instrument with a clean, damp cloth; as needed, use a soap and
water solution of 8 to 10 parts water to 1-part dish soap, like Dawn®. To achieve a more serious cleaning,
wipe down the instrument with a bleach and water solution of approximately 50 parts water to 1 part bleach
as recommended by the US Centers for Disease Control and Prevention (CDC).
