All Your
Questions

Read All FAQs
What comes with the Blakmint Liquid Retainer Cleaner?
Each 250ml bottle of Blakmint Liquid Retainer and Denture Cleaner comes with a small measuring cup, so you can measure the right amount for a 10% solution or for the 4ml fill used with the Blakmint case.
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.
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?
One 250ml bottle covers up to 5 months of cleaning. Used as a 10% solution it lasts up to 5 months. Used with the Blakmint case you only need 4ml of cleaner mixed with 36ml of water per fill, which is designed to give you up to 12 months of cleaning in total.
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 linked to skin and respiratory irritation and are a common ingredient in 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.

Amazing cleaner, don’t buy the tablets!!

Second time buying this product for my grind guard, ignore other reviews as these haven’t read the instructions or understood the product and compared it to retainer tablets. This is a concentrated cleaner which is diluted so of course the bottle might smell strong but it’s not at all when diluted for use. It doesn’t last 30 days either, mine lasted me 9 months because it’s reusable and diluted. I had the kit with their leakproof case and my routine had been so much easier.

This is a liquid cleaner so it can’t be compared to retainer tablets so it doesn’t fizz. I personally prefer this as there’s no gunk to clean after every single use. Also, this is “concentrated” so the bottle is diluted and there are NO chemical smells at all when diluted just mint.

Definitely no cloudy residue, in fact it’s squeaky clean. I’ve switched from tablets for several reasons, no persulfates in this, convenience, cleaning ability.

Thank you 🙏

Works great!

BLAKMINT's Ultrasonic Cleaner works well both in an ultrasonic machine, and as a soak.

I've tried this twice, and it has worked excellently both times. Firstly a soak for a retainer, which worked just as good as my usual tablets. Second, in an ultrasonic machine which has really brought the retainer up nicely. Great job BLAKMINT!

The only downside is that it smells unpleasant. It's not particularly minty, and has a strong chemical smell which doesn't go well with anything that you're planning on putting in your mouth - namely anything that it's designed for!

At £13.00, this may seem expensive for 30 uses but in reality you are unlikely to need it everyday. I'll be using it perhaps once a week for my retainers, so I expect it to last a good 6 months. For that, it's good value considering the cleaning power.

Overall, 4/5 - works great, but just doesn't smell that good.

Cloudy mouth guard

Bought to clean my mouth guard with a dental ultrasonic cleaning machine. Advert showed removed cloudiness but actually caused cloudiness in my mouth guard that wasn’t there before. However, hopefully it’s being cleaned!
