• This concentration kills bacteria, viruses, and fungi without damaging plastic
• Rinse each tip under running water for 10 to 15 seconds after soaking
• Never mix vinegar and peroxide together, as they react to form irritating compounds
Monthly Sanitizing Cycle
For an extra layer of protection, perform a monthly sanitizing flush to eliminate lingering microbes deep in the system.
Use Mouthwash Solution for Disinfection
Monthly sanitizing with mouthwash provides enhanced microbial control. Here’s how to do it:
• Mix antibacterial mouthwash and water in a 1:1 ratio
• Fill the reservoir with the solution and let it sit for 10 minutes
• Power on the flosser briefly to circulate the solution through internal tubing
• Empty the reservoir and run 3 to 4 full cycles of clean water to flush residue
