INVISALIGNCleaning Crystals for Clear Aligners and Retainers, (50 Packets)[Amazon-developed Certification] Compact by Design

The crystals do a great job cleaning my Invisalign aligners. I’m on a 7-day cycle and usually use them around day 3 or 4. They get the aligners really clean, but the smell afterward is awful.

These clean Invisalign "retainers" better than any other product that I've tried. They are pricier than alternative products. However, they remove stains much better.

The pack last you a while, which is very good and cleans them well.

I use these every day to soak my retainer as advised by the dentist. Retainer looks like new every day for months. Great product. Have reordered and will keep on using.

Does clean up and shin Invisilign trays.

This does work well, but if you are sensitive to SLS it might cause you problems. I did notice a big difference in how my mouth felt in the morning after having my Invisalign in all night when I used this- it tasted a lot less gross than it had after nights I had cleaned my trays with other products. I like that this product does not have blue dye in it, however it also has enough SLS to give me canker sores, so it does not work for me. Be advised that in order for it to work well you need to put your trays into a watertight container that you can shake. It will clean ok if you just dump it all into a glass and let it sit for 15 minutes, but is more effective if you follow the directions and shake it in a sealed container, and honestly probably safer if you or anyone in your home ever absent-mindedly drinks from any glass within reach.

Easy peasy instructions to follow. Glad they come in a back of so many. However, I wasn't sure if they were for daily use, but after an online search I found out they are safe. Unless I missed it, I did not see it on the insert that comes with the box. Overall, I will be ordering these again.

Good product
