It is very simple to clean invisible braces for children. After taking them out, gently brush them with a soft-bristled toothbrush using water and liquid soap. Do not use toothpaste as it may contain abrasives that can scratch the surface. Make sure to remove any food particles that have accumulated on the aligners. Then, rinse them thoroughly and use a clean cloth to dry them before putting them back in. You may also soak them in water and liquid soap solution for thirty minutes to an hour.
