MIRACLE
I have used every single product from Amazon and my local hardware store on the hard water stains on my mirrors, shower glass and on the shower tile. This is the only product that has worked on the hard water stains. I live in the Coachella Valley and the water is incredibly hard with huge amounts of mineral deposits that destroy faucets and leave deposits constantly on toilet bowls and shower walls. This product does the trick very well.
