I have used Listerine for years and decided to try the Listerine Ultraclean Cool Mint. I rinsed with this mouthwash after brushing. As I was about to leave for work, I looked in my bathroom mirror because my mouth felt filmy and lo and behold, my tongue was bright blue. I had to brush again for a good 5 minutes to get the blue off my tongue. Later that night I brushed and rinsed with Ultraclean and my tongue was blue again. What is up with this? I will not continue using this product.
No, I would not recommend this product
