Cleaning your Invisalign trays isn’t as simple as it sounds. In fact, many people unknowingly damage their aligners by using the wrong products or skipping crucial steps. If you’ve been using toothpaste or mouthwash to clean them, you could be compromising both hygiene and effectiveness.

While it may seem like a minor part of your oral care routine, how you clean your aligners can significantly affect your treatment. Even well-meaning shortcuts — like using hot water or abrasive brushes — can lead to warped, scratched, or discolored trays that not only look unsightly but also reduce the efficacy of your aligners.


In this comprehensive 2025 guide from Transformation Dental, we’ll break down exactly how to clean Invisalign trays the right way. From daily cleaning routines to deep cleaning methods, dentist-recommended products, and common mistakes to avoid — consider this your ultimate resource.

We’ll also answer the most common patient questions and share expert-backed recommendations to ensure your aligners stay fresh, clear, and effective throughout your treatment journey.


Why Cleaning Invisalign the Right Way Matters

Dirty aligners don’t just smell bad — they can harbor bacteria, stain easily, and affect the clarity of the trays. This reduces their aesthetic appeal and can impact your oral health and the overall effectiveness of your Invisalign treatment.

Keeping your Invisalign clean ensures:


  • Optimal hygiene: Removes plaque, food particles, and bacteria, helping prevent gum disease, bad breath, and tooth decay.
  • Clear appearance: Prevents yellowing and cloudiness, keeping your aligners nearly invisible.
  • Effective treatment: Avoids misalignment from warped or compromised trays, ensuring they maintain proper fit and function.


Neglecting aligner hygiene not only puts your oral health at risk, but may also lead to delays in your treatment timeline and the need for replacement trays, which can be costly.


Aligners spend most of their time inside your mouth, so keeping them clean is just as important as brushing and flossing your teeth. Consider Invisalign hygiene as part of your daily dental routine.


Daily vs. Deep Cleaning: What’s the Difference?

Daily Cleaning Routine

  • How: Rinse aligners with lukewarm water and gently brush using a soft-bristle toothbrush and unscented, clear antibacterial soap.
  • When: Every morning and night, and after eating (before reinserting trays)
  • Why It Matters: Prevents the buildup of bacteria, plaque, and food particles that can cause odor or affect tray transparency. Daily maintenance keeps your trays fresh and minimizes staining.


Deep Cleaning (2–3 Times a Week)

  • Purpose: Removes biofilm, tough stains, and deeper bacteria buildup that daily cleaning might miss
  • How: Soak aligners using specialized or homemade solutions (more below)
  • Frequency: Ideally every 2–3 days, especially if aligners start to smell, discolor, or feel slimy
  • Why It Matters: Deep cleaning restores clarity, eliminates hidden bacteria, and maintains the longevity of your trays. It's essential for overall aligner hygiene, especially for coffee or wine drinkers.

What NOT to Use on Your Invisalign Trays

Avoid these common mistakes that can warp, stain, or damage your aligners:


  • Toothpaste: Too abrasive, can scratch trays and make them more visible
  • Alcohol-based mouthwash: Can dry out and discolor trays over time
  • Boiling water or dishwasher: High heat warps the plastic and alters the fit
  • Colored or scented soaps: May leave stains or introduce irritating chemicals to your mouth
  • Hard-bristled brushes: Cause micro-scratches that lead to tray cloudiness and odor retention


These cleaning shortcuts can compromise your aligners’ performance, increase bacterial buildup, and ultimately lead to longer or less effective treatment. Always choose gentle, aligner-safe cleaning products.

Final Tips & FAQs

  • Can I use retainer cleaning tablets for Invisalign?

    Yes, as long as they're aligner-safe and free of harsh chemicals.

  • What if I forget to clean my trays for a few days?

    Start with a deep clean (peroxide or cleaning crystals) and check for signs of buildup or staining.

  • How often should I replace aligners if they stain?

    Staining usually doesn’t affect performance, but consult your orthodontist if trays become cloudy or smell persistent.

  • Can I eat or drink while wearing Invisalign trays?

    No. Always remove your aligners before eating or drinking anything other than water. Food and beverages can stain or warp the trays.

  • Is it okay to clean Invisalign with denture cleaners?

    Only if they are labeled as safe for clear aligners. Many denture tablets contain ingredients that may be too harsh or abrasive for Invisalign trays.
