Bests & Worsts Reviews from Amazon

I am not sure what these did for my toilet except turn the water dark blue. I was better off before I bought these. I ended up throwing out the other 3. I do not feel they cut down on my cleanig the toilet at all. I have purchased similar items before and I could see a difference. I assumed since it was a Clorox product that this would be a great product. It was just a blue mess.
