Retainer must haves 🦷 I have used the ultrasonic machine for over a year on my retainers and need to rescue it from my old house today it cleans Jewerly too. 10/10 amazing purchase for all things cleansing and brightening. For retainers toothbrushes do not get them clean enough below I have my travel case (UV Sanitation light) and the “denture” cleaner that works great at gentle cleaning. Just wait till water turns clear then rinse a lot. I use the tablet once a week and the UV to store them. LTKBeauty LTKFindsUnder50
