How to Clean Invisalign, Spark and Angel Aligners with EverSmile (2026 Patient Guide)

Patients ask the same questions about aligner cleaning every week — “Can I use toothpaste?” “Why did mine go cloudy?” “Can I leave them in the cup with denture cleaner?” This article is written for practices to share with patients. It covers what to clean with, what to avoid, and a simple daily routine built around the EverSmile range — the cleaning system most ANZ aligner practices recommend.

Why aligner-specific cleaning matters

A clear aligner sits against the teeth for 22 hours a day. Saliva, food residue, plaque biofilm and bacterial colonies build up on both the inner and outer surfaces. Standard tooth-brushing reaches the outside of the aligner but cannot get under the inner surface where it contacts the tooth. Toothpaste — designed for tooth enamel — is too abrasive for the soft PETG and TruGEN materials clear aligners are made from, and creates microscopic scratches that trap stain and odour. Boiling water permanently warps the aligner. Coloured mouthwashes stain the plastic.

That's why the cleaning routine has to be aligner-specific. The EverSmile range was developed for exactly this purpose — gentle enough to use on PETG-based aligners (Invisalign, Spark, Angel Aligner, ClearCorrect) and PETG retainers, strong enough to dissolve the biofilm a toothbrush can't reach.

The three EverSmile products and what each one is for

1. EverSmile AlignerFresh Original — foam (in-mouth, after meals)

EverSmile AlignerFresh Original is a wearable foam cleaner. Apply a pea-sized amount inside the aligner and put the aligner back in. The foam works against the aligner and the tooth surface continuously while the aligner is worn — cleaning the aligner AND cleaning the contact surface of the tooth at the same time, without removal.

When to use: After every meal. Quick rinse of the aligner, apply foam, replace. Particularly important after coffee, tea or red wine — the main staining culprits we see in adult cases.

Why patients prefer it: No taking the aligner out at restaurants, no separate cup to carry, no rinsing step needed after.

2. EverSmile AlignerFresh Spray — quick clean (in-mouth or on-aligner)

EverSmile AlignerFresh spray is the same active formulation in a spray bottle. Spray inside the aligner, replace. Same wearable cleaning action, faster application.

When to use: The carry-anywhere version — fits in a handbag, car console or work bag. Adolescent patients tend to reach for the spray; the bottle is small enough they can keep one in a school bag.

3. EverSmile AllClean Cleaning Minerals — soak (24–48 hour deep clean)

EverSmile AllClean Cleaning Minerals is the soak product. One sachet in a glass of water with the aligner in it, soaked while the patient eats a meal or sleeps. AllClean dissolves the plaque, calcium and biofilm that wearable cleaners can't reach.

When to use: Once every 24–48 hours, depending on staining tendency and aligner usage. Most adults soak nightly during the first three days of a new tray (when bacterial colonies are establishing on the fresh aligner surface), then every second day from there.

Why it matters: Even with perfect spray and foam use, a 100-day Invisalign series will accumulate biofilm. Soak cleaning is the only way to remove it without abrasion.

The full daily routine (share this with patients)

1. On wake: Rinse the aligner under cool running water before re-inserting. Brush teeth as normal — never with the aligner in.
2. After breakfast: Rinse aligner, apply EverSmile AlignerFresh foam or spray, replace.
3. After lunch: Same.
4. After dinner: Same — or, if it's the chosen soak time, drop the aligner in a glass of water + AllClean minerals while you eat dinner. Replace aligner after.
5. Before bed: Soft toothbrush plus clear unscented soap (no toothpaste) on the aligner is fine as an occasional deep clean. AlignerFresh and AllClean handle daily cleaning without this step.

What to avoid

Share this list with every aligner patient at the delivery appointment. The “I ruined my aligner” mistakes we see most often, ranked by frequency:

• Toothpaste — abrasive, creates microscopic scratches that trap stain.
• Boiling water — permanently warps the aligner.
• Hot dishwasher cycles — temperature plus detergent damage trays.
• Coloured mouthwashes (especially blue or green) — stain the plastic permanently.
• Denture cleaning tablets not rated for clear aligners — many contain peroxide concentrations or persulfates that craze PETG.
• UV sterilisers unless explicitly aligner-rated — some wavelengths degrade aligner material.
• Coloured drinks while wearing the aligner — coffee, tea, red wine, fruit juice. The aligner traps these against the tooth, which causes both aligner staining AND enamel staining.
• Hot drinks while wearing the aligner — even short exposure to 70 °C+ can soften and distort the tray.

How long aligner cleaning takes patients to get right

Most patients take 2–3 weeks to settle into a consistent routine. The bottleneck is usually not motivation — it's that they weren't given the right products at delivery. Practices that issue an EverSmile starter kit at the new-aligner appointment see noticeably lower mid-treatment refinement rates, because the aligners themselves stay clean enough to maintain trackability across the full 1–2 week wear cycle.

For practices: building a take-home cleaning kit

The take-home pack that most ANZ aligner practices have settled on contains:

• 1× EverSmile AlignerFresh foam — the daily driver after meals.
• 1× EverSmile AlignerFresh spray — the handbag/car version.
• 1× pack of EverSmile AllClean Cleaning Minerals — for the every-second-day soak.
• 1× hinged retainer/aligner case for patients to soak in.

Issue this kit at the first delivery appointment. Most practices recover the cost via a small markup on the kit and use it as a patient retention touchpoint — the patient comes back to the practice when they run out, not to a chemist or Amazon.

Order EverSmile products and patient-issue retainer cases in practice-pack quantities from our aligner accessories collection. Same-day dispatch from our Brisbane warehouse on orders placed before 2:30 pm AEST.
