I really like this cleaner. It has an excellent minty fresh taste and love how clean it leaves my retainer. The water turning blue is a perk. The price is affordable and ZenGates customer service is top notch. I plan on using this product going forward and would recommend it to anyone looking for a high quality retainer cleaner.

The product is very simple to use and works well on my clear plastic retainers. It doesn't leave any odour, and cleans the retainers pretty well.

I have Invisalign and struggled to get them clean with the toothbrush and soap method. They get pretty smelly fast! These tablets are great. I use them 1-2 times a week with warm water in a cup and my trays come out shiny and clean. No aftertaste after rinsing with water. Plan to keep these around a while as I am on tray 5/40!

I have used retainer cleaner for over 15 years when I started wearing a retainer. I have tried just about every 4- or 5-star cleaner on Amazon. I saw the Zengate cleaner's review score pulled ahead of my old cleaner (which was good), so I figured I would give it a try. I am so glad that I did! The Zengate cleaner is much better testing - minty vs. chemical-tasting. Also, I cleans super fast (less than 15 min) and tents to get in all of the little grooves of metal really well on my retainers. Highly recommend!

These did a great job for cleaning Invisalign. They shipped quickly and they were easy to use. The ingredients are your basic dental appliance cleaning ingredients, nothing odd. In response to the review complaint that they’re not FDA approved — they wouldn’t be, they’re not a drug. Neither are cosmetics, face wash, hair colour, vitamins…yet no one seems to worry about using them. This is a great product. It did a bang up job cleaning my water bottles. Recommend.

This is the 3rd cleaner I’ve tried and I’m so happy w it that I just purchased my 2nd box. I use it to clean my night guard. It’s easy to use. The individual packets tear easily and cleanly – this was a big factor for me. I plop the tab in some water w my night guard and the night guard is nice and fresh within minutes. I would buy this product again and recommend it to anyone looking for a night guard cleaner.
