One of the biggest appeals of clear aligner teeth trays is their nearly invisible design. But stains can quickly make them cloudy, yellow, or unpleasant to wear. The good news? Stains are preventable and removable with the right care.

This guide explains the causes of aligner stains, safe cleaning methods, and the best products to keep your trays looking crystal clear.


Why Clear Aligners Stain

Even though clear aligner for teeth trays are made from durable plastic, they can absorb discoloration if not properly maintained. Common causes include:

  • Coffee, tea, and red wine – deeply pigmented drinks cause yellowing.

  • Smoking or vaping – nicotine leaves brown stains.

  • Colored mouthwash – dyes in mouth rinses stick to trays.

  • Improper cleaning – brushing with toothpaste scratches the surface, trapping stains.

  • Skipping aligner cleaning – bacteria and plaque buildup can make trays cloudy.


How to Remove Stains from Clear Aligner Teeth

1. Use Retainer Cleaner Tablets

Soak aligners in a retainer cleaner tablet solution, such as Weiss Naturals. These remove stains and odor in just 15 minutes.

2. Invisalign Cleaning Crystals

Specifically designed for Invisalign, Invisalign cleaning crystals dissolve quickly and target discoloration effectively.

3. Ultrasonic Cleaners with Solution

Ultrasonic devices paired with tablets or crystals provide a deep clean, removing stubborn stains and buildup.

4. DIY Soap and Water Rinse

For daily upkeep, use a mild clear soap and soft brush. Avoid abrasive toothpaste.
