It is important to maintain high standards regarding hygiene and cleanliness in physical computing settings to prevent spreading of germs and bacteria.

If you are using the micro:bit in a setting where one device is likely to be used by multiple people, for example, a classroom or library you should familiarise yourself with local protocols for hygiene, such as washing your hands before and after touching a computer device.

There are options available for sanitising electronic devices, such as using cotton swabs and isopropyl/ethanol, or an ultrasonic/UV-C lightbox, but as the micro:bit is a Printed Circuit Board (PCB) with exposed electronic components, these methods are not recommended as they may result in damaging the device.

Safe use of the micro:bit is of utmost importance to the Foundation and we encourage you to read our safety guide for more information.
