Introduction
Clear aligners like Invisalign are designed to be invisible — but many users notice unsightly white spots or cloudy marks appearing over time.
These spots are not only unattractive but can also be a sign of poor hygiene or mineral build-up.
This article explains why white spots form, how to prevent them, and why the Sonic Pro ultrasonic + UV cleaner is the most effective solution for keeping aligners crystal clear.
What Causes White Spots on Aligners?
-
Plaque build-up → dried biofilm leaves white residue.
-
Hard water deposits → calcium deposits form cloudy stains.
-
Improper cleaning → toothpaste scratches or soaking in mouthwash leaves residue.
-
Dry storage → promotes build-up and odor.
Common Myths About Removing White Spots
❌ Toothpaste will clean them → actually scratches aligners.
❌ Bleach or vinegar soaks → corrosive and unsafe.
❌ Boiling water → permanently warps aligners.
The Best Way to Remove and Prevent White Spots
1. Daily Cleaning with Sonic Pro
Ultrasonic cavitation blasts away biofilm and debris 95% more effectively than brushing [1]. UV light reduces bacteria that cause cloudy build-up.
2. Optional Tablet Boost
Use Sonic Dental Cleaning Tablets weekly with Sonic Pro to reduce mineral staining and odor.
3. Rinse in Cool Water Only
Never use hot water or alcohol-based products.

FAQs
Q: Can I polish white spots away?
A: No — you risk scratching the aligner. Use ultrasonic cleaning to prevent them forming in the first place.
Q: Do aligner cleaning crystals remove white spots?
A: They help reduce odor but are less effective on stains compared to ultrasonic cleaning.
Conclusion
White spots on aligners are caused by plaque, minerals, and poor cleaning routines. The most effective solution is daily use of the Sonic Pro ultrasonic + UV cleaner, with an optional weekly tablet boost for extra freshness.
