Colgate Optic White WhiteSeal Mouthwash

This mouth wash has a strong taste at first but I got used to it :p I have been using this once a day and I noticed that my teeth got whiter after a week or two! After that I did not notice any more changes. (I should probably rinse twice a day). This...

Toothpastes and mouth washes that promise to whiten normally fall through because the whitening ingredient only has contact with your teeth for such a small amount of time.. However, the colgate optic white toothpaste+mouthwash has really shown results...

My mouth did feel clean after using this. I can't get over how nasty it tasted though.
