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 mouthpeice 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 leak proof 32oz cylinder container with a one piece cap that has a controlled dropper tip. This is the 'Economy' size and is used to refill the 2oz or 8oz Mi-T-Mist product. Don't be fooled by the copycats trying to duplicate our look and feel with their, what we like to call 'Green Stuff'', it doesn't compare. We were the originators of the mouthpiece cleanser and our high standards for quality and great products is why we are the industry leader.
