What is included in the Blakmint Starter Kit?
The Starter Kit includes a 250ml Liquid Retainer and Denture Cleaner with a small measuring cup and the U shaped retainer cleaning and storage case. It is the simplest way to clean, store and reuse your solution for retainers, aligners and other removable dental appliances.
Why does the Starter Kit help me save money on retainer cleaner?
The U shaped case follows the natural shape of your retainer, so it needs less water and cleaning solution than a larger container. That is why one bottle can last up to 12 months when used with the case.
Is this kit suitable for Invisalign® and clear aligners?
Yes. The Blakmint Liquid Retainer Cleaner and U shaped case are suitable for retainers, clear aligners, Invisalign® trays, whitening trays, night guards, sports mouthguards, partial dentures and clip in veneers.
Is the retainer cleaner persulfate free?
Yes. Blakmint Liquid Retainer and Denture Cleaner contains no persulfates and uses glacial acetic acid for effective everyday cleaning, so there are no fizzing tablets, cloudy residue or daily sachets. It is a UK registered medical device made in Finland.
How long does the liquid retainer cleaner last?
With the case included in this kit you only need 4ml of cleaner mixed with 36ml of water per fill, so one 250ml bottle is designed to last up to 12 months.
How many days can I reuse the cleaning solution?
You can reuse the same cleaning solution for up to 6 days when it is used as directed, which means less waste, less plastic and lower cost than replacing cleaning tablets every day.
What does the 99.99% bacteria reduction claim mean?
The 99.99% figure is based on ASTM E2315 time-kill testing against a mixed bacterial inoculum of P. aeruginosa, E. coli, S. aureus and E. hirae, with 99.99% reduction measured at 20 minutes and at least 99.99% at later time points. Results relate to the sample tested.
What size is the retainer 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.
Is the retainer 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.
Can I use the case as a cleaning bath and for storage?
Yes. The case is a cleaning bath and a protective storage case in one. Soak your retainer in the reusable solution, then rinse and store it in the same case at home or on the go.
*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.
**Up to 5 months from one 250ml bottle when mixed as a 10% solution. Up to 12 months when used with the Blakmint case, which needs only 4ml of cleaner mixed with 36ml of water per fill.
