How do you clean mold off retainers?

To clean mold off retainers, start by soaking them in a mixture of equal parts white vinegar and water for about 30 minutes. After soaking, gently scrub the retainer with a soft toothbrush to remove any remaining mold. Rinse thoroughly with warm water and then soak again in a solution of baking soda and water for extra disinfection. Ensure the retainer is completely dry before storing it to prevent future mold growth.
