How to Clean Retainers: Tips, Tricks, Cleaners, and Natural Solutions
Ever taken your retainer out and noticed a funky smell or white buildup? You’re not alone. Retainers can collect bacteria, plaque, and even mold if you’re not careful.
The good news? Cleaning your retainer doesn’t have to be complicated.
This step-by-step guide will show you exactly how to keep your retainer clean, clear, and odor-free using both daily care tips and weekly deep-cleaning tricks—so you avoid nasty bacteria, damage, and expensive replacements.
Whether you’re using a clear plastic retainer like Essix or Invisalign, or a wire-and-acrylic Hawley, this article covers it all.
Why Cleaning Your Retainer Matters (And What Happens If You Don’t)
Let’s get real—your retainer spends hours in your mouth. It’s exposed to food debris, bacteria, and saliva. That makes it a breeding ground if left uncleaned.
Here’s what can happen:
| Problem | What It Causes |
|---|---|
| Bacteria Buildup | Leads to bad breath, oral infections, and can even cause gum disease. |
| Plaque & Tartar | Hardens over time, making cleaning tougher and increasing risk of cavities. |
| Discoloration | Retainer looks cloudy or yellow. Often smells bad, too. |
| Damage Over Time | Dirt weakens the material. Might warp, crack, or stop fitting well. |
Not cleaning your retainer doesn’t just feel gross—it affects your oral health, orthodontic results, and your wallet.
How to Clean Your Retainer (Quick Answer for the Busy Folks)
- Every day: Rinse with lukewarm water. Gently brush using a soft toothbrush and mild, clear liquid soap.
- Once a week: Soak in a retainer cleaning tablet or a white vinegar and water mix to deep clean.
- Avoid: Hot water, alcohol-based cleaners, and toothpaste—these can damage your retainer.
Now let’s break that down in detail.
Know Your Retainer Type: Materials Matter
Different retainers need slightly different care based on what they’re made of:
| Retainer Type | Material | Cleaning Notes |
|---|---|---|
| Clear Plastic (Essix, Invisalign) | Thermoplastic | Sensitive to heat, abrasives, and alcohol. Stick to mild cleaners. |
| Hawley | Acrylic base + metal wire | More durable. Still avoid harsh chemicals or boiling water. |
| Permanent/Bonded | Metal wire glued to teeth | Clean like braces—brush thoroughly around them daily. |
Clear retainers stain faster and are easier to scratch. Hawley retainers can handle a little more, but still need gentle care.
Your Daily Retainer Cleaning Routine (Takes 2 Minutes!)
Your goal here is to remove food, saliva, and light buildup before it turns nasty. Follow these steps:
- Immediately rinse your retainer with lukewarm water when you remove it.
- Gently brush it using a soft-bristle toothbrush.
- Apply mild, clear soap (like dish soap or baby shampoo). Avoid anything with added dyes or strong scents.
- Rinse again thoroughly. Dry it completely before putting it back in or storing.
💡 Tip: Brush your retainer over a towel or bowl of water in case you drop it. These things crack easily.
Weekly Deep Cleaning Methods (Natural & Store-Bought)
This is where you tackle hard deposits, bacteria, and smell. You’ve got options:
1. Retainer Cleaning Tablets (Effervescent Cleaners)
These are made for retainers and dentures. Drop one tablet into a cup of warm water and let your retainer soak for 15–20 minutes.
- Kills 99.9% of odor-causing bacteria
- Easy to use
- Found in dental sections of most pharmacies (look for effervescent denture and retainer cleaning tablets)
🛑 Don’t soak overnight—long exposure can weaken the plastic over time.
2. White Vinegar Soak (Natural Deep Clean)
Mix equal parts white vinegar and lukewarm water. Soak your retainer for 15–30 minutes.
Vinegar’s acetic acid helps dissolve mineral deposits and kill odor-causing bacteria. Rinse thoroughly afterward to avoid the lingering vinegar smell.
3. Baking Soda Paste (Use Sparingly)
Make a paste using baking soda and a few drops of water. Apply with a toothbrush and scrub gently.
⚠️ Warning: Baking soda is abrasive. It can scratch clear plastic retainers and make them dull. Limit use to once or twice a month, and avoid on Invisalign trays.
What NOT to Use on Your Retainer
Some cleaning methods can do more harm than good. Avoid these:
- Boiling water – Will warp thermoplastics. Retainer won’t fit.
- Toothpaste – Contains abrasives. Scratches plastic, causes cloudiness.
- Alcohol or bleach – Too harsh. Can damage the material and leave toxic residue.
- Dishwasher or microwave – Instant regret. Melts or ruins retainers completely.
Smart Retainer Storage Tips
Cleaning is only half the battle. You’ve gotta store it right too.
- Use a ventilated case to keep airflow and reduce bacterial growth.
- Clean the case weekly—it gets gross faster than you’d think.
- Never wrap in napkins—that’s how most retainers get accidentally tossed.
- Avoid leaving it in hot cars or near windows—heat warps plastic retainers.
Quick FAQs

A: Nope. Most mouthwashes contain alcohol, which can dry out and damage your retainer.
Q: My retainer smells even after cleaning. What should I do?
A: Try a deep-clean soak with vinegar or tablets. If the smell lingers, it might be time for a replacement.
Q: How do I clean my retainer at school or work?
A: Keep a small soft brush and mini bottle of mild soap in your case. Rinse with water and brush after meals.
