Mi-T-Mist is a topical antimicrobial designed to cleanse the mouthpiece and provide a refreshing agent that will remove residue build-up from the instrument. Easy to use: spray the fine mist on the mouthpiece then let evaporate (about 45 seconds). To freshen and clean the inside of the instrument, spray liberally into the instrument and immediately swab. Mi-T-Mist evaporates quickly and assists in eliminating moisture and bacteria. This product comes in a 8oz cylinder container with a fine mist sprayer.
