Real Routines Love
We don't like to brag, so we'll let our customers show you.
Fab Cleaning Brush!
"Great little brush, having one side with a smaller ball shape end means it gets into the tiniest parts to clean. The cardboard store tube is sturdy, strong and planet-friendly too."
Love It
"The liquid solution is so much better than the standard cleaning one I was given initially that tasted of chlorine. This is pleasant, and the brush gets in the corners better."
So Easy To Use!
"It arrived quickly, the instructions were clear and easy to follow, and the results speak for themselves. My retainer looks and feels fresh, no lingering odours or film."
Perfect For Keeping Retainers Clean
"The set comes with a handy size brush that fits into all the parts that are hard to clean, a leak-resistant retainer case, a tool to remove the retainer from the pot, liquid cleaner and mint chews."
Amazing Kit
"I used so many retainer cases, and they're always rubbish. This case is well-made and feels durable. Keeping the retainers in the liquid mixed with water seems to work, keeping them clean is so much easier."
100% Persulfate-Free
The Truth About Tablets You Probably Didn't Know
Persulfates Are A Known Skin & Respiratory Irritant In Most Fizzing Tablets.
Skin & Respiratory Irritant
Same Family As Hair Bleach
Keeps Releasing While Soaking
Legally Classed As Hazardous
It's why more retainer and aligner wearers are switching to persulfate-free liquid cleaning.

Liquid Cleaner
The reusable, persulfate-free formula that does the actual cleaning, lab tested to reduce 99.99% of bacteria* and safe to reuse for up to 6 days per fill.

Holds your retainer securely while it soaks and doubles as a travel case, so you can clean and store it in one place, at home or on the go. The case measures 8cm wide by 3cm high, with an internal depth of 2.3cm per side, so please check these measurements against your retainer to make sure it fits. It is leak resistant, but not leak proof.

Why People Are Switching From Tablets
So Convenient
"My daughter used to find cleaning her retainer with tablets so tedious every single day, and I worried about her hygiene. Now she just pops the brush in her school bag and gives it a clean between classes, so much easier for both of us."
Rachel P.
Parent Of A Retainer Wearer
Easy To Use
"I love that the chewies come in three different shapes and have a handle, so I'm never touching my retainer with my fingers. The brush is small enough to keep in my desk drawer too, perfect for a quick clean after lunch."

What is Blakmint Liquid Retainer Cleaner?
Blakmint is a concentrated, persulfate-free liquid cleaner for retainers, aligners, dentures, night guards and other removable oral appliances. Mix it with water in your case, soak, and rinse, no fizzing tablets, no cloudy residue, just a clean appliance every time.
What is included in the Blakmint Full Kit?
The Full Kit includes a 250ml Liquid Retainer and Denture Cleaner with a small measuring cup, the U shaped retainer cleaning and storage case, a dual head retainer cleaning brush, a curved retainer removal hook and 3 mint flavoured aligner chewies. It is a complete retainer care kit for cleaning, storing, removing and seating retainers, clear aligners and Invisalign® trays.
Is the Full Kit persulfate free and safe for Invisalign® and retainers?
Yes. The liquid cleaner is persulfate free, uses glacial acetic acid, and is a UK registered medical device made in Finland. It is suitable for retainers, clear aligners, Invisalign® trays, whitening trays, night guards, sports mouthguards, partial dentures and clip in veneers.
How do I clean my retainer with the Full Kit?
Brush your retainer gently with the dual head brush and lukewarm water, then soak it in the case with 4ml of Blakmint cleaner mixed with 36ml of water. Rinse before wearing, and reuse the same solution for up to 6 days when used as directed.
How is Blakmint different from cleaning tablets?
Tablets are single-use, fizz with persulfates, and often leave a cloudy film behind. Blakmint's liquid formula is reusable for up to 6 days per mix, contains no persulfates, and dissolves gunk completely, with none of the daily waste.
How long does one bottle last?
This kit includes the case, so your 250ml bottle of liquid cleaner is designed to give you up to 12 months of cleaning in total when you use 4ml of cleaner mixed with 36ml of water per fill in the case.
Is Blakmint safe for all retainers and appliances?
Yes. Blakmint is designed for retainers, clear aligners, Invisalign® trays, whitening trays, night guards, sports mouthguards, dentures, clip-in veneers and partial dentures, one bottle covers everything.
How do I use Blakmint?
Fill your case or a cup with water, add the measured amount of Blakmint liquid, and soak your appliance for a few minutes. Rinse thoroughly before wearing. We don't recommend soaking overnight every time, but doing so occasionally is fine. The same mix can be reused for up to 6 days.
Is Blakmint safe for ultrasonic cleaners?
Yes, unlike fizzing tablets, Blakmint's still liquid formula reaches every surface inside an ultrasonic cleaner without foaming or blocking contact, so you get a genuinely thorough clean.
Does Blakmint contain persulfates?
No. Blakmint is 100% persulfate-free. Persulfates are a known skin and respiratory irritant found in most fizzing tablets, Blakmint's formula cleans effectively without them.
What does the 99.99% bacteria reduction claim mean?
Based on ASTM E2315 time-kill testing against a mixed bacterial inoculum of P. aeruginosa, E. coli, S. aureus and E. hirae. 99.99% reduction measured at 20 minutes; ≥99.99% at subsequent measured time points. Results relate to the sample tested.
Is the retainer brush portable?
Yes. It's small enough to keep in a bag, pencil case or desk drawer, so you can brush your retainer wherever you are, not just at the bathroom sink.
Is the case leak proof?
The case has a silicone sealed lid and is leak resistant, but it is not leak proof. Keep it upright when it is filled with liquid and empty it before transporting.
What size is the case and will my retainer fit?
The case measures 8cm wide by 3cm high, with an internal depth of 2.3cm per side. Please check these measurements against your retainer to make sure it fits before ordering.
What are the hook and chewies for?
The hook lets you remove your retainer hygienically without touching it directly, and the chewies help you bite it fully back into place once it's back in, handy if you're out and about.
No More Guesswork
One Kit. Everything Sorted.
No shopping around, no asking in chat rooms for recommendations, everything you need arrives together in one order. It's a registered medical device, tested and regulated, not an unverified marketplace knockoff with no safety standards behind it.
