Make daily dental appliance care easier with this 45kHz ultrasonic retainer cleaner machine. Designed for retainers, dentures, aligners, mouth guards, and night guards, it uses high-frequency ultrasonic technology to generate millions of micron-scale bubbles every second, helping lift away 99.99% of stains and buildup from hard-to-clean areas without damaging your dental appliances. For a more complete cleaning routine, this retainer cleaner is equipped with 4 UV lights and offers 4 cleaning modes, making it easy to choose the right setting for a quick refresh or deeper care. You can use water alone for everyday cleaning, or add retainer cleaning tablets when extra cleaning support is needed. The UV lights automatically switch off when the lid is opened for added peace of mind during daily use. Built for convenience, this retainer cleaner machine features a soft-close lid, double-hole lid design, 4 non-slip rubber pads, and low-noise performance under 40 dB for a quieter and more stable experience. The compact 200ML tank and portable handle make it easy to use at home, in the office, or while traveling. In addition to dental appliances, it can also be used for jewelry, glasses, and other small personal items.
