Review (5/5): Tastes much better than the Invisalign cleaning system
I also couldn't bear the taste of the Invisalign cleaning system. Steraligner has a minty flavor that suits me much better. As somebody reviewed before, I make a new a new diluted batch only once a week and a bottle lasts me a few months. Note though that I always rinse the trays in water before putting in the solution and after soaking for plus minus an hour while having a meal, I always brush all surfaces of the trays with a kid/small head tooth brush. Small steps that you can build into a habit to reduce staining of the trays and going through the cleaning solution too fast.
