If you’re using Invisalign, keeping your aligners clean is one of the most important steps in maintaining a healthy smile throughout your treatment. Clear aligners are designed to be nearly invisible, comfortable, and easy to wear, but without proper care, they can become cloudy, develop odors, or hold onto unwanted bacteria. The good news? Cleaning them doesn’t have to be complicated. With a few simple habits, you can keep your aligners fresh while supporting the progress of your treatment.
In this guide, you’ll find practical tips on how to clean your Invisalign aligners, what to avoid, and how maintaining good hygiene contributes to effective Invisalign.
Why Cleaning Your Invisalign Aligners Matters
Your aligners sit closely against your teeth for most of the day—usually 20 to 22 hours. Because of this, anything left on the surface (like plaque, food particles, or bacteria) can quickly transfer to your teeth and gums. Clean aligners help prevent:
- Bad breath
- Cloudiness or stains
- Bacterial buildup
- Irritation of your gums
- Slowdowns in treatment progress
More importantly, clean aligners support better oral health throughout your entire Invisalign journey.
Clean Your Aligners Twice a Day
A simple routine of cleaning your aligners every morning and night helps prevent buildup. Just like brushing your teeth, this daily care keeps your Invisalign trays clear and comfortable.
How to Clean Your Aligners: Step-by-Step
1. Rinse Them with Lukewarm Water
Always use lukewarm—not hot—water. Hot water can warp the plastic and affect the fit of the aligners.
2. Brush Gently with a Soft Toothbrush
Use a soft-bristled brush dedicated to cleaning your aligners. Avoid toothpaste, as many formulas are abrasive and can scratch the surface, causing cloudiness.
3. Use Clear, Gentle Soap
Unscented, clear antibacterial soap is a great option for routine cleaning. It removes bacteria and eliminates odors without damaging the aligner material.
4. Rinse Again Thoroughly
Make sure all soap residue is washed away before placing them back in your mouth.
5. Clean Your Teeth Before Wearing Them
Putting clean aligners on unbrushed teeth allows bacteria to get trapped. Brushing and flossing first gives you the best results and protects your oral health.
Deep Clean Your Invisalign Aligners Regularly
In addition to daily cleaning, it’s beneficial to give your aligners a deeper clean several times a week.
Options for Deep Cleaning:
- Invisalign cleaning crystals
- Denture tablets (non-colored)
- Retainer cleaning solutions
- Clear orthodontic cleaning gels
These help remove tougher buildup that daily brushing may miss. Just avoid anything colored, as dyes can stain the aligners.
What NOT to Use When Cleaning Invisalign Aligners
Many cleaning habits seem harmless but can actually damage your aligners. Avoid:
- Toothpaste (too abrasive)
- Colored soaps (can stain)
- Hot water (may warp plastic)
- Scented soaps (leave an unpleasant taste)
- Alcohol-based mouthwash (can discolor or weaken plastic)
- Bristle-heavy scrubbing (may scratch aligners)
Keeping your aligners clear and odor-free means sticking to gentle cleaning methods.
Why Cleaning Aligners Helps Invisalign Work Better
Clear aligners need to fit your teeth precisely in order to move them effectively. Build-up and improper cleaning can interfere with how well they sit on your teeth. Fresh, clean aligners:
- Fit more accurately
- Stay invisible
- Reduce risk of irritation
- Prevent odors
- Support better oral hygiene

Tips for Keeping Your Aligners Clean Throughout the Day
Always Store Aligners in Their Case
Never place them in a napkin or pocket. This prevents loss, damage, and contamination.
Rinse After Every Meal
Before placing your aligners back in, a quick rinse removes lingering food particles and bacteria.
Brush After Eating
Food particles trapped under aligners can cause staining or decay.
Keep a Travel Kit
Include a small toothbrush, case, soap, and floss so you can keep up with cleaning on the go.
Supporting Your Aligners—and Your Smile
Clean aligners don’t just improve comfort; they help your Invisalign treatment work at its best. Making a few good daily habits part of your routine ensures clear, fresh trays and supports better long-term oral health.
