ToLife LW-UC888 ultrasonic retainer cleaner brings a simple cleaning routine to compatible retainers, aligners, dentures and mouth guards. Its 48 kilohertz ultrasonic system helps loosen everyday residue in a 200 milliliter stainless steel tank. One button selects four programs: a 5 minute ultrasonic and ultraviolet light cycle, a 10 minute pulsed ultrasonic and ultraviolet light cycle, a 10 minute ultrasonic only cycle or a 10 minute ultraviolet light only cycle. The digital display shows the remaining time, and the included drain basket helps you lift out small items after cleaning. Measuring approximately 4.8 inches wide by 4.8 inches deep by 3.74 inches high, the plug-in unit fits on a bathroom counter. Use cool water and confirm that each appliance or accessory is suitable for ultrasonic cleaning. | Tolife | | Ultrasonic Retainer Cleaner with Four Programs and Digital Timer | Best Buy
