I've been doing invisible aligners for the last 9 months so I've been through every possible cleaning routine... peroxide, water and toothbrush, clear mouthwash, denture tablets and products specifically made for clear aligners. This is the final one in the group that I've tested, and this one is the most aggressive. When I say most aggressive, I say that because there is a recommended time limit of the soak, of just a few minutes, and when you pour the powder into the water or empty glass to add water the chlorine smell can almost catch your breath, almost like pouring shock powder into a swimming pool or opening a tightly closed bin of chlorine pool tablets. That being said, it does clean, and very similar to Retainer Brite, it starts as a blue and fades to clear once the work is all done. This product works, but I clean my retainers several times a day, each time that I have them out to eat or drink. That being the case, I don't really like the 5 minute limit this product puts on how long you should leave the retainers in the bath, and often when I am eating or drinking it's more than 5 minutes. If I'm traveling for work and have had to take my aligners out and not properly wash them before putting them back in throughout the day and have minimal time for maintenance, this would be a great product for the "once a day aggressive clean". If I'm cleaning more than once a day I would probably prefer not to get the chlorine whiff and would prefer to stay with my "several times a day" option,Polident 3-Minute Anti-Bacterial Denture Cleanser Tablets, Triple Mint Fresh, 84 Count which at least in my experience and estimation isn't as harsh as this product. That being said, a natural comparison would be between this product and https://www.amazon.com/Efferdent-Power-Clean-Crystals-Count/dp/B006ZHP7XM/ref=sr_1_1_a_it?ie=UTF8&qid=1497207206&sr=8-1&keywords=efferdent%2Bcrystals&th=1. I have used several boxes of those crystals and I'd say they're a fraction of the strength of this product, but again if you're cleaning more than once a day, that may be fine. Before this product, I would say that the Efferdent crystals and https://www.amazon.com/Retainer-Brite-Tablets-Months-Supply/dp/B005GRGARE/ref=sr_1_1_s_it?s=beauty&ie=UTF8&qid=1497207336&sr=1-1&keywords=retainer%2Bbrite&th=1 were a tie for first place. What I like about this product, Retainer Brite and the Polident 3 minute is that they leave a slick feeling on the retainer / aligner after cleaning and I think this also help is resist things sticking to it over time. With the clear braces, after a certain amount of cleaning they start to feel "dried out" like a headlight plastic of a car, and sometimes eventually crack. So if I'm cleaning a lot, I'd use something like Polident 3 minute, if I'm cleaning less, I may mix in the Efferdent Crystals once, and if I'm only able to clean once a day I would use this or the Retainer Brite. Probably far more information than you wanted, but that's my 9 months worth of tablet experience. I didn't even mention the mouthwashes and peroxide! I'll sum it up this way: I stayed with the tablet and crystal options once I discovered them.
