Kleenite on Invisalign?

[Trickycoolj]

Found a product at the drugstore this evening called Kleenite, looks like it's a bottle of crystals of some sort. Says it's safe for orthodontic appliances including clear aligners and I don't see persulfate in the ingredients list. I do see baking soda (sodium bicarbonate, yay British YouTube cooking channels!) Has anyone tried Kleenite before? It was between $6 and $7 at the local drugstore Bartell Drugs which tends to carry harder to find products and isn't usually the cheapest among drugstores. Glad I checked out the dental aisle before I left!

Used it several times now with no staining. Even left a previous set of trays in a glass of kleenite overnight and didn't see any problems or staining. Would be easy to travel with since its powder or find at a drugstore if you forget cleaning stuff in a trip.
