How often should I clean my Invisalign trays?

Clean your Invisalign trays before every time you put them back in: do a quick daily clean with a soft‑bristled toothbrush and water (a small amount of toothpaste if you use it), rinse thoroughly, and store trays in their case when not wearing them. [1]

Quick takeaways

• Quick clean with a soft brush and water before each insertion. Rinse immediately after removing and keep trays in their protective case.
• Use Invisalign Cleaning Crystals or Cleaning Foam about once a week or 'as needed' for deeper cleaning.
• Do not soak in mouthwash or use denture cleaners; avoid hot water or hot drinks while wearing to prevent warping. [1, 2]

Daily quick cleaning: before each reinsertion

Invisalign’s patient instructions say to clean your aligners prior to each insertion using a soft‑bristled toothbrush with water and a small amount of toothpaste, then rinse thoroughly after cleaning. [1]

The U.S. Food and Drug Administration’s consumer guidance for clear aligners also notes patients should remove aligners for cleaning and for routine oral care, reinforcing the manufacturer advice to clean trays when they are taken out. [3]

Deeper cleaning: weekly or as needed

For more thorough cleaning (to control odor or remove deposits), Invisalign materials recommend using their cleaning products — Cleaning Crystals or Aligner Cleaning Foam — about once a week or as needed. [1, 2]

The manufacturer wording 'as needed' is permissive and not tied to peer‑reviewed evidence that a specific weekly schedule improves clinical outcomes; it’s a practical patient-care recommendation rather than a clinical trial finding. [1, 2]

What to avoid when cleaning or wearing aligners

Align Technology specifically warns against using denture cleaners or soaking aligners in mouthwash (these can damage the surface and make trays more visible) and cautions against hot water or hot drinks while wearing aligners because heat can warp the trays. [1]

Practical tips and how Smilo can help

Rinse aligners immediately when you remove them, brush them quickly before reinserting, and always store them in the protective case to avoid loss or damage. [1, 2]

Smilo can help you keep a consistent cleaning routine by letting you log each cleaning session and set configurable regular‑clean and deep‑clean reminders so you track daily quick cleans and weekly deeper cleans.
