How to Remove Hard Water Stains From Granite

2 Materials
1 Hour

Are you frustrated by those chalky white streaks around your faucets? Want to remove those stubborn hard water stains from granite counter tops? Our simple tutorial gets the job done without using any harsh chemicals.
My house cleaning style is probably best described as clean enough.So while my kitchen sink and counters are wiped down and sanitized daily, some tasks don’t get my attention very often.
The best solution for hard water stains and mineral deposits is to consistently dry any areas that become wet.But who has time to wipe down the kitchen faucets every. single. time. a little water splashes around them?!And if you have kids in the house? Fuhgettaboutit!You need to be careful with granite because most cleaners made for hard water stains are too harsh and can damage natural stone.
Which is why I rely on my hard water stain secret weapon: a pumice stone.Caution: Be sure to check with your granite installer or test using the pumice stone in an inconspicuous area to be sure it doesn’t scratch your stone! After you’ve confirmed it’s safe to use a pumice stone on your granite, just follow these simple steps.
Turn off the water and drain the lines
Either stop up your sink so that you can have a basin of water or get a small bucket of water.There should be a shut-off valve under your kitchen sink. In my kitchen, I have to turn off both the hot and the cold water lines.Then turn on your faucets to let any water still in the line to drain.Next loosen the fittings under your sink so that you can lift the sprayer, taps, and faucet away from the granite.
Remove the fixtures from the granite
You may need to actually remove the handles before you can lift the fittings away from the counter.My handles have a little screw that needs to be loosened (see that hole?).
Then I needed to loosen that bolt plus one under the sink to get the cap to lift away from the counter.
Repeat the steps for your other handle and the faucet so that they all lift up from the counter surface.The rings for my faucets just barely lifted up but it was enough for me to get the area cleaned with the pumice stone.
Use a wet pumice stone to remove the mineral deposits
Go to town scrubbing the hard water stains away!The pumice stone will break down as you use it because it is much softer than the granite.I also cleaned the corner seam along the back of the sink area.That powder you see is the pumice stone remnants.
Wipe up the dust
Once you’re satisfied that the hard water stains are gone, reattach everything you loosened up and turn the water back on to your sink lines.
Reattach all the hardware
Just reverse the process to reattach the hardware and the water lines. Turn the water back on.Sit back and enjoy the results!For more simple ideas, visit Simply2moms!

      I understant my reply above did not address what this post is about, how to remove hard water deposits from granite. That is another beast. The best way if possible is prevention. I'm interested in what is safely working for others to remove hard water deposits without causing damage, over short or long term.

    I only use MR. CLEAN MAGIC SPONGES on my granite and around the faucets, also my glass top stove. The small "wipes" they now offer are much easier to use around tough to get at areas like faucets. It won't scratch and no chemicals. Wet it, squeeze it out and wipe the stains, etc. Only thing I use.

    I use a pumice stone to clean the hard water rings in my toilets. Works like a charm!
