It is best to clean your aligners before each insertion. This can be done using cold water and a toothbrush (without toothpaste). Soaking aligners in cool water and vinegar or Retainer Brite will remove any stains or debris (other than gum). Simply place your aligners in a cup of water and add one tablet of Retainer Brite, which will turn the water blue. Once the water is clear again, your aligners will be too! Rinse them thoroughly in cold water before re-inserting. It is best to clean your aligners while they are out during mealtimes, to avoid extra time out of the mouth.
Do not use warm or hot water, denture cleaners or mouthwash as these will distort the aligners.
When taking your aligners out to eat or drink, remember to store them in the protective box provided. Avoid placing them in tissue or your pockets to prevent accidentally damaging or discarding them.
