Care and Maintenance

An ounce of prevention is better than a pound of cure.

We recommend you wash your mouthpieces with warm water and mild dishwashing soap and then air dry it on a clean cloth. In classroom and group situations, we recommend the use of the Red Sterisol cleaner for its proven capability to clean, deodorize and sanitize mouthpieces. Please do not immerse your mouthpieces in, or clean your mouthpieces with, isopropyl, or other members of the hydroxyl group of products.

If you need a quality swab, mouthpiece patches, and other cleaning materials, please consider adding a Backun Care Kit to your Order.

Note: All New Mouthpieces from Backun are cleaned, disinfected and sterilized for your health and safety.
