A few of quick tips to keep your microphone hygiene at the highest level.
Use your own microphone windscreen, and make sure you have plenty of spares.
Ensure the microphone can dry out after each class i.e rotate microphones between classes.
Use a dry towel to wipe down the microphone after every class.
Don’t try to clean or wipe the capsule with sanitisers, cleaners, or alcohol wipes: these types of cleaners can dissolve the sweat-proof coating and cause damage.
Own your own microphone pouch belt.
Where possible, use your own microphone. The EMic is a great choice for individual instructors.
