What to Avoid When Cleaning Your Invisalign: Expert Advice

Your Invisalign trays are practically invisible—until stains, odors, or scratches make them noticeable. While using the right Invisalign cleaner is important, knowing what NOT to do is just as critical. Many cleaning mistakes can shorten the lifespan of your aligners, cause discomfort, or even damage them beyond repair.

This guide breaks down the common cleaning mistakes, what to use instead, and how to keep your aligners crystal clear.

Why Avoiding Certain Cleaning Methods Matters

Cleaning your trays incorrectly can:

• Warp the aligners due to hot water exposure

• Scratch the surface, making them look cloudy

• Leave chemical residue that can irritate your mouth

• Fail to remove harmful bacteria

7 Common Invisalign Cleaning Mistakes to Avoid

1. Using Toothpaste on Your Aligners

Toothpaste may seem harmless, but it contains abrasives that scratch the plastic. Over time, those scratches trap bacteria and odors.

Better option: Use Invisalign cleaning crystals or a gentle retainer cleaning tablet.

2. Soaking in Hot Water

Hot or boiling water can warp the shape of your aligners, making them useless.

Better option: Always soak in lukewarm water with an approved Invisalign retainer cleaner.

3. Using Harsh Chemicals Like Bleach

Bleach or strong cleaning agents can cause toxic residue and weaken the aligner material.

Better option: Opt for persulfate-free cleaning solutions like Weiss Naturals tablets.

4. Skipping Daily Cleaning

Even skipping one day can cause plaque buildup and lingering odor.

Better option: Follow the best way to clean retainers daily—rinse after removal and deep clean at least once a day.

5. Using Colored Mouthwash

Colored or scented mouthwash can stain your aligners and alter their taste.

Better option: If you must use mouthwash, choose a clear, alcohol-free formula.

6. Storing Wet Aligners in a Case

Moisture creates a breeding ground for bacteria.

Better option: After cleaning, dry your aligners before storing.

7. Ignoring Deep Cleaning Tools

Over time, brushing alone isn’t enough to remove microscopic buildup.

Better option: Use an ultrasonic retainer cleaner once a week for a thorough cleanse.
