I've had retainers for almost 20 years and they are gross, despite the fact that I brush them every day. Over time, plaque has built up and they have yellowed. I have been using these tablets for a few days and it has helped tremendously. They are too far gone to ever look new but I'll take any help I can find. I wish I had known about these years ago! Yet another good iHerb find.
This stuff is the real deal, cleans my oral appliance better than anything else, with absolute minimal effort. Have never tasted or otherwise sensed any film or residue left over. Been using this stuff for a few years, don't see any degradation in my apnea appliance. Will buy this again and again and again and again,
On to my second box. I use it for my sleeping mouthguard. I let my mouthguard sit in water with this product all day and its not a problem . I was my mouthguard after its been sitting in this - there's no after taste or residue. It definitely cleaned the mouthguard which was yellowing - it's remained a clear, neutral colour. I feel it's a safe product and recommend it.
I have tried every cleaning agent that I have thought of and nothing worked on my night guard, with time the color changed to darker and darker, and some bad stains appeared in some places. I tried the retainer cleaner, I left my guard in hot (not boiling) water with the cleaner for the hole day, It almost went back to the original color, after another day it is as good as new.
