If you’re one of the millions of people rocking Invisalign or clear aligners, you know the struggle. By day three of a new set, they start to lose that “invisible” crystal-clear look. By day seven, despite your best scrubbing, they can start to look cloudy and feel… well, a little gross.
You’ve probably wondered: “Can I just toss these in my Creworks ultrasonic cleaner?”
The short answer? Yes, absolutely. In fact, it’s one of the most effective ways to keep your aligners hospital-clean and odor-free. Here’s everything you need to know about doing it safely.
Why the Ultrasonic Method Beats the Toothbrush
Most orthodontists tell you to brush your aligners with a soft toothbrush. While that’s fine for a quick rinse, it has two major flaws:
- Micro-Scratches: Toothbrush bristles can create tiny scratches on the plastic. These scratches actually give bacteria and plaque a place to hide, making your aligners turn yellow faster.
- Missed Spots: Aligners have deep grooves and tight corners that bristles simply can’t reach.
An ultrasonic cleaner uses “cavitation” to create millions of microscopic bubbles that implode against the aligner. These bubbles scrub every single micron of the surface—inside and out—without scratching the plastic.
The Creworks Guide to Cleaning Invisalign
To get that “brand new” shine back, follow these simple steps:
1. The Right Solution
Don’t just use plain water. To break down the proteins and bacteria from your saliva, use:
- A specialized retainer cleaning tablet (like Retainer Brite).
- A 50/50 mix of water and hydrogen peroxide.
- Mild dish soap (just a drop or two).
- Avoid: Mouthwash (the alcohol and dye can stain or warp the plastic) and Bleach (it’s too harsh for something going in your mouth).
2. Watch the Temperature (Crucial!)
Invisalign and other clear aligners are made of medical-grade thermoplastic. Heat is their enemy.
The Rule: Use lukewarm or room-temperature water.
- The Warning: While Creworks cleaners have built-in heaters, keep the heater OFF for your Invisalign. If the water gets too hot (typically above 40°C or 104°F), the aligners can warp, meaning they won’t fit your teeth properly anymore.
3. The Timing
You don’t need a long cycle. 3 to 5 minutes in the ultrasonic bath is usually enough to vibrate away all the plaque and buildup.
Pro-Tips for Aligner Maintenance
- Rinse First: Give your aligners a quick rinse under the tap to remove loose debris before putting them in the tank. This keeps your cleaning solution “fresher” for longer.
- Degas: If you’ve just filled the tank with fresh water, run the machine for one cycle before putting your aligners in. This removes excess air bubbles that can cushion the cleaning action.
- Daily Routine: Many Creworks users keep a small 2L unit on their bathroom counter and run their aligners through a cycle every morning while they eat breakfast. It’s the easiest way to ensure your “invisible” braces stay truly invisible.
