What is the proper way to clean a retainer. I got my braces off last month and have been on retainer so far. I think my retainer isn’t getting cleaned well enough, maybe I’m doing it wrong? My dentist said to brush my retainer with a toothbrush and hand soap whenever I brush/take it off. And when I start wearing it only at night, to soak it in something, I forgot what is was. What is the proper way? I wear is every day, throughout. So should I brush it, cuz there still dirt on it I can’t get off. Or should I soak it in something kind of cleaner, or just water, overnight?
