‘Sterialigner’ and ‘cleaning crystals’ are products by Invisalign that are specifically made to effectively clean your aligners. Depending on the product you’re using, the steps generally involve soaking your aligners in the cleaning solution for a said amount of time, rinse and voila! Your aligners are ready to be worn again.

Aside from the options mentioned, there are several other cleaning solutions that are mild yet effectively clean your Invisalign aligners. They include baking soda, retainer cleanser or distilled white vinegar diluted in water.

  • Do use a toothbrush with soft bristles (use a separate toothbrush to brush your teeth) and gently brush your Invisalign aligners to effectively remove stubborn food particles.
  • Do clean both your teeth and Invisalign aligners thoroughly, as part of your morning and night routine.
