To clean Invisalign aligners, rinse them every time you remove them and gently brush them once or twice a day with a soft toothbrush and lukewarm water; soak them regularly in Invisalign cleaning crystals or a denture cleaner. Avoid hot water, abrasive toothpaste, and colored or scented soaps, which warp or stain the trays. Clean aligners stay clear and odor-free.

At Solana Orthodontics, we teach every Solana family member this quick routine, because cloudy, smelly aligners are almost always a cleaning issue.

How do you clean aligners daily?

  • Rinse aligners under lukewarm water each time you take them out.
  • Brush gently with a separate soft toothbrush and clear, mild soap or water.
  • Soak daily or every few days in cleaning crystals or a denture-cleaning tablet.
  • Brush and floss your teeth before putting aligners back in, so food isn’t sealed against your enamel.

What should you avoid?

  • Hot water — warps the plastic and ruins the custom fit.
  • Regular toothpaste — abrasive; leaves micro-scratches that cloud the trays.
  • Colored or scented soaps — can tint or leave residue.
  • Eating or drinking (except water) with aligners in — stains and traps sugar.

How do you keep aligners from smelling?

Odor comes from bacteria and dried saliva. Rinsing immediately, brushing daily, and soaking regularly prevent it. If a set still looks cloudy near the end of its wear period, that’s normal — you’ll move to a fresh set soon. The habits mirror caring for a retainer; see our guide on how to clean a retainer.

Why clean aligners matter for results

Aligners sit against your teeth 20–22 hours a day, so anything on them touches your enamel and gums for hours. Keeping them clean protects your oral health and keeps them invisible — which keeps you wearing them. Since Invisalign works only when the trays are in, comfortable, clean aligners help you stay on schedule. Considering Invisalign? Dr. Sandra and our team will get you started with everything you need.

Why does cleaning your aligners matter so much?

Aligners sit against your teeth for 20 to 22 hours a day, so whatever accumulates on them is pressed against your enamel and gums for hours at a time. Dirty aligners can trap bacteria, cause bad breath, and raise your risk of cavities and gum irritation — the opposite of what you want during treatment. Keeping them clean also keeps them clear and truly invisible, which is a big part of why you chose aligners in the first place. A quick daily routine protects both your oral health and your confidence.

Daily cleaning versus a deeper clean

Think of aligner care in two layers. Daily: rinse them every time you remove them, and gently brush them with a soft toothbrush and clear, mild soap or water once or twice a day. Deeper clean: soak them in Invisalign cleaning crystals, a denture-cleaning tablet, or a retainer cleaner every day or two to disinfect and clear buildup you can’t see. Because you move to a fresh set regularly, each pair only needs to stay fresh for its short wear period, which makes upkeep easy.

How do you remove stains and odor from aligners?

Cloudiness and odor come from bacteria, dried saliva, and mineral buildup. Consistent rinsing and daily brushing prevent most of it, and a regular soak handles the rest. Avoid colored or scented soaps and mouthwashes, which can tint the plastic, and never use hot water or abrasive toothpaste. If a set looks a little cloudy near the very end of its wear period, that’s normal — you’ll switch to a clear new set shortly. Persistent staining usually means the aligner needs a soak, not a scrub.

Eating and drinking with aligners in

The golden rule: only water goes in with your aligners. Eating with them risks cracking the trays and traps food and sugar against your teeth, while coffee, tea, soda, and other colored or hot drinks stain and can warp the plastic. Take your aligners out for meals and drinks, rinse your mouth and the trays before reinserting, and ideally brush first. Building this habit keeps your aligners clear, your teeth healthy, and your treatment on track.

How should you store your aligners?

When aligners aren’t in your mouth, they belong in their protective case — never wrapped in a napkin (the fastest way to accidentally throw them out) or left loose where they can be crushed, lost, or chewed by a pet. Keep your current set’s case with you, and hold onto your previous set as a backup in case a tray cracks or a new one is lost. Store aligners away from heat, since a hot car or direct sun can warp the plastic and ruin the fit in minutes.

How do you keep aligners clean while traveling?

Travel with a small kit: your case, a travel toothbrush, and cleaning crystals or tablets. Because you can’t always brush right after eating on the go, rinse your mouth and your aligners with water before popping them back in, and do a full clean when you’re able. Pack aligners (and any backups) in your carry-on, not checked luggage, so they’re never lost with your bags. A little planning keeps your routine — and your treatment — on track wherever you are.

Keeping your aligners their clearest

The payoff for a consistent cleaning routine is aligners that stay virtually invisible and comfortable throughout treatment. Rinse them every time they come out, brush and soak them regularly, keep only water in your mouth while wearing them, and store them in their case away from heat. These small habits take only minutes a day and protect both your oral health and the discreet look that made you choose aligners in the first place. Clean, clear aligners are also ones you’ll happily keep wearing — which is exactly what keeps your treatment on schedule.

Frequently Asked Questions

Can I use denture cleaner on my aligners?

Yes, a denture-cleaning tablet is a common and effective way to soak aligners. Invisalign cleaning crystals are made specifically for this purpose. Rinse thoroughly afterward before wearing.

Why are my aligners turning yellow?

Usually it’s buildup from inconsistent cleaning or from eating and drinking with them in. Rinse after every removal, brush daily, and soak regularly. Avoid colored drinks while wearing them.

Can I use mouthwash to soak my aligners?

It’s best avoided — many mouthwashes contain color and alcohol that stain or dry the trays. Use cleaning crystals or a denture cleaner instead.

Can I drink coffee with my aligners in?

Only water. Coffee, tea, and colored drinks stain aligners and can warp them if hot. Remove the trays, then rinse your mouth and aligners before reinserting.

How often should I deep-clean my aligners?

Rinse and brush daily, and soak every day or two. Since you change sets regularly, each pair only needs to stay fresh for its wear period.
