rinse trays every time they’re out, brush them gently with clear soap morning and night (no toothpaste — it scratches), soak in cleaning crystals or retainer tablets a few times a week, and never let hot water near them.
The daily two minutes
- Every removal: rinse under cool water before casing them — dried saliva is where cloudiness and smell begin.
- Morning & night: brush trays gently with a soft brush and clear liquid soap. Skip toothpaste: it’s abrasive and micro-scratches turn trays foggy.
- Before re-insert: brush your own teeth — trapping lunch under plastic against enamel for hours is the one real dental risk of aligner life.
The deep clean
A few times weekly, soak 15–20 minutes in Invisalign cleaning crystals or any retainer-cleaning tablet; a half-white-vinegar soak is the budget version. This kills the film brushing misses.
The destroyers
- Hot water — warps trays instantly and permanently. Cool or lukewarm only, always.
- Coffee, tea and red wine with trays in — stains plastic in days. Anything but water: trays out.
- Coloured mouthwash soaks — tint trays blue-green.
- Napkin storage — how most aligners die (in a cafeteria bin). Case, always.
Perspective
Each aligner serves only 1–2 weeks, so perfection isn’t required — but the final retainers serve for years, and this exact routine keeps them fresh. Build the habit now, keep it forever. New to aligners entirely? Start with the complete Invisalign guide.
How it works at our practice
We give every aligner patient the two-minute routine at delivery and check tray condition at every visit — cloudy or warped trays tell us about hot water and skipped rinses. The same routine keeps your final retainers fresh for years, so it's worth building the habit from tray one.
Frequently asked questions
Can I clean Invisalign with toothpaste?

Can I use hot water on aligners?
Never. It warps them instantly.
How often should I deep-clean trays?
Cleaning crystals or retainer tablets a few times a week; a half-vinegar soak is the budget version.

Dried saliva from skipped rinses. Rinse every time they come out.

The bottom line
Rinse every removal, brush with clear soap morning and night, soak a few times a week, never hot water, always the case. Two minutes a day, clear trays for the whole treatment.
If it were our own family
Rinse every removal, clear soap morning and night, a soak twice a week, never hot water, always the case. We'd build the habit from tray one, because the final retainers need it for years.
