The COJA Ultrasonic Cleaning Pod is designed for aligners, retainers, dentures, night guards, and mouthguards. It also works well for small items like jewelry or toothbrush heads.

COJA combines ultrasonic vibration with UV sterilization to eliminate debris, odor, and bacteria that soaking or brushing alone can’t remove. Each cleaning cycle uses high-frequency sound waves to deliver a lab-grade clean.

The COJA Pod offers two quick options — a 3-minute or 5-minute cycle. Both include automatic ultrasonic cleaning with integrated UV light disinfection.

Yes. The ultrasonic cleaning is gentle on aligner and retainer plastics, ensuring no scratches, warping, or discoloration. Always use water only — avoid alcohol, bleach, or abrasive cleaners.

After each use, empty and dry the tank, then wipe the exterior with a soft damp cloth. Store the unit in a cool, dry place and never submerge it in water. For optimal performance, keep the lid closed during UV cleaning.
