Clean Invisalign case maintenance is just as important as caring for your aligners themselves, yet many patients overlook this crucial aspect of their treatment routine. Your Invisalign storage case serves as a protective shield for your aligners during meals, brushing, and other times when they’re removed from your mouth. Without proper cleaning, this seemingly simple accessory can quickly become a harbor for harmful bacteria that threatens both your aligner hygiene and overall oral health.
At Lansdowne Family Dental, we’ve observed that patients who maintain pristine storage cases experience fewer complications and better Invisalign treatment outcomes. While most focus their attention on aligner care, the storage case requires equal dedication to prevent bacterial buildup and unpleasant odors.
Learn the proven techniques below to effectively clean your Invisalign case, ensuring optimal hygiene and protection for your aligners throughout your entire treatment journey.
Supplies You’ll Need To Clean Your Invisalign Case
Cleaning your Invisalign case takes only a few affordable items you likely already have at home:
- Warm water
- Mild soap
- A toothbrush or small scrub brush
- Clean hand towel
You probably won’t need to buy anything special. Just gather the supplies above before getting started washing the case.

Step 1: Rinse the Case
First, grasp the case over a sink. Gently rinse inside and out with comfortably warm water. This helps clear out any initial debris or residue before deeper scrubbing.
Step 2: Apply Mild Soap
After rinsing, place a tiny dab of gentle soap onto your cleaning toothbrush bristles. Non-abrasive hand or dish soap works perfectly.
Dip the bristles into the streaming warm sink water to form a lather with the soap before scrubbing. Avoid soaps with heavy perfumes or odors that may cling to plastics.
Step 3: Gently Scrub Inside and Out
With soapy bristles ready, gently begin scrubbing every inner and outer surface of your Invisalign case. Clean all sides, corners, indents, and crevices allowing lather and friction to lift grime.
Pay careful attention to scrubbing where aligner trays contact or slide against the case walls upon insertion or removal. Any buildup risks transfer back onto aligners later placed inside.
Step 4: Rinse Away Soap
Once scrubbed, thoroughly rinse away all soap and debris back under flowing warm tap water. Rinse both inside and externally until the water runs clear.
No soap residue that could interact with your aligner chemistry should remain when stored.
Step 5: Dry the Case
Finally, dry your Invisalign case fully with a clean lint-free towel. Pay special attention to wiping out interior corners or crevices that may trap lingering moisture.
Once fully dry, the case will be fresh and ready for clean aligner tray storage on the go!
Extra Invisalign Case Cleaning Tips
Keep these additional pointers in mind for ideal Invisalign case care:
- Allow the case to air-dry between uses rather than closing moist – this prevents mold risks inside
- Consider buying backup cases for convenience rather than repeatedly reusing unwashed cases
- Seek durable case designs with antimicrobial properties for added protection
- Replace noticeably warped or damaged cases compromising cleanliness
And remember to always wash your hands before handling aligners whenever possible to prevent transferring skin oils onto the plastic.
