Review on Iron OUT Automatic Toilet Bowl Cleaner - Efficiently Repels Rust and Hard Water Stains, 6 Tablets, for Household Toilet Cleaning, Pack of 1 by Larry Blanco

I recently learned how hard water is affecting my life and how easy it is to prevent these problems. It was one of them. I cleaned my toilet, installed one of these as directed, and checked it regularly for a while until I got fed up. Then one day I found I had hard water brown spots again and sure enough the puck was gone. I would say it took 2-3 months. Next time I'll try one that turns the water blue so I don't have to worry too much about how long it lasts. Water stains just fall off: Instant Power Cleaner Tank Cleaner. Blow me away And probably made this product work better. It doesn't clean a dirty toilet. As a result, a clean toilet can prevent limescale stains for longer. While I'm here, if you have hard water, expensive dish soap is worth it, and diluted apple cider vinegar is great for hair.
