Does anything really work this well? I had high expectations for getting a years worth of hard water ect… out of my toilet. If I had to take a pumice stone to it I would be there for hours. After 3 applications of EdFred my toilet looks brand new. The scent reminds me of a Sprite soda, yet it’s very faint. I will recommend this to everyone I know and I will continue to use this product from now on. Excellent product. Delivers what it says it will do. Thank you very much!
