I use this mouthwash daily! It's meant to be used before brushing so I rinse with a half of cap full before I brush in the morning and at night. I like that it doesn't have a strong taste. To me it doesn't have much taste at all. I'm a smoker and coffee drinker and I've noticed that it has visibly removed the surface stains on my teeth. It leaves my mouth feeling clean and fresh. For the price it is a definite must try. It's very affordable and works. If you are looking for "extreme" whitening results this is not the mouthwash for you, but it does whiten and strengthen your teeth.
