First, try to rinse your aligners each time you take them out. Doing so will keep bacteria and plaque build-up to a minimum, which makes cleaning them much easier.
You should soak your aligners once a day using a special Invisalign® solution. You can let your aligners soak while you’re eating breakfast or dinner. Then, rinse them and brush them with water and hydrogen peroxide or a gentle antibacterial soap. Brush your aligners twice a day.
One of the great things about the Invisalign® system is that you can brush and floss like normal. You don’t have to take the time to thread your floss as you do with traditional metal or porcelain braces.
