That chalky white crust around your faucet. The cloudy film on the shower door. The ring in the toilet that comes back a week after you scrub it. Those are hard water stains, and if you live in Pendleton or anywhere in Madison County, you've probably fought them for years.
Hard water stains are mineral deposits, mostly calcium and magnesium, left behind when water dries on a surface. Indiana water averages around 14 grains per gallon, which is very hard, so every drop that dries leaves a little more buildup behind.
The good news: you can clean almost all of it with things already in your kitchen. Here's how to remove hard water stains from every part of your home, and how to stop them from coming back.
How to remove hard water stains from faucets and showerheads
Faucets and showerheads get the worst of it because water sits on them and dries over and over. The easiest fix is an overnight vinegar soak.
- Fill a plastic sandwich bag with plain white vinegar.
- Slip it over the faucet or showerhead so the crusty part is underwater, and secure it with a rubber band.
- Leave it overnight.
- In the morning, scrub what's left with an old toothbrush, especially around the nozzles.
- Rinse with water and wipe dry.
For the base of the faucet where the bag won't reach, soak a paper towel in vinegar, wrap it around the buildup, and let it sit for an hour before scrubbing.
How to remove hard water stains from shower doors
Glass shower doors show hard water more than anything else in the house. Vinegar and baking soda handle most of it.
- Spray the glass with undiluted white vinegar and let it sit for about 10 minutes.
- Sprinkle baking soda on a damp microfiber cloth or non-scratch sponge.
- Scrub in small circles. The fizz helps lift the film.
- Rinse with warm water.
- Dry the glass completely with a clean microfiber cloth or squeegee.
The tip that makes the biggest difference: keep a squeegee in the shower and give the glass a quick wipe after every shower. Water can't leave spots if it doesn't dry on the glass.
How to remove hard water stains from toilets, tubs, and sinks
Toilet rings: Pour 1 cup of white vinegar and 1/4 cup of borax into the bowl. Swish it around the ring, let it sit for 15 minutes, then scrub with a toilet brush and flush. For an old, thick ring, turn off the water and flush first so the vinegar isn't diluted.
Tubs and porcelain sinks: Spray with white vinegar and let it sit for 15 minutes. Sprinkle baking soda on a scrub brush or sponge, scrub in circles, and rinse well.
Tile and grout: The same vinegar spray works on ceramic and porcelain tile. Use a small brush on the grout lines and rinse well afterward.
How to get rid of spots and cloudy glasses from the dishwasher
If your glasses come out of the dishwasher looking foggy, try this.
- Soak the cloudy glasses in a 50/50 mix of warm water and white vinegar for 15 to 30 minutes.
- Scrub gently with a soft sponge.
- Rinse and dry with a soft, lint-free towel.
To keep the film from coming back, keep the rinse aid dispenser full and use the hotter rinse or sanitize setting if your dishwasher has one.
One thing to know: if a glass is still cloudy after a vinegar soak, it may be etched. Years of hard water can permanently scratch the surface of glass, and no cleaner will bring that back.
What not to use on hard water stains
- Never mix bleach with vinegar or any other acidic cleaner. Together they release chlorine gas, which is dangerous to breathe. If you've already used bleach on a surface, rinse it well with plain water before using vinegar.
- Don't use vinegar on natural stone. Marble, travertine, limestone, and granite can be etched by acids. Use a cleaner made for natural stone instead.
- Skip steel wool and scouring pads on glass, chrome, and polished fixtures. They leave tiny scratches that make the surface look dull, and those scratches give new minerals more places to cling.
Why hard water stains keep coming back
Every method above works. The problem is that none of them last. The minerals are in the water itself, so every time water dries on your faucet, glass, or tub, the stains start building again. That's why the shower door you scrubbed on Saturday is cloudy again by Wednesday.
You can keep up with it using a squeegee, rinse aid, and a weekly vinegar spray. Or you can stop it at the source. (Not sure your home has hard water? Here are 7 signs of hard water to look for.)
The permanent fix: a water softener
A water softener removes calcium and magnesium from your water before it ever reaches your faucets. No minerals in the water means nothing left behind when it dries. Faucets stay shiny, glass stays clear, and the toilet ring stops coming back.
At Fresh Water Systems, we install water softeners for as low as $1,999, with professional installation included. (That price is for homes with an existing bypass loop. Curious what a softener would cost for your home? Read our guide to what a water softener costs in Pendleton.)
Every visit starts with a free water test, so you'll know exactly how hard your water is before you decide anything.

Hard water stain FAQ
Plain white vinegar works on most surfaces. For tough buildup, follow it with baking soda on a non-scratch sponge, or add borax for toilets.
Yes. Lemon juice and citric acid are both mild acids that dissolve mineral buildup the same way.
Usually it's mineral film from hard water. A vinegar soak removes it. If they stay cloudy, the glass may be permanently etched.
Wiping surfaces dry helps, but the only permanent fix is removing the minerals from the water with a water softener.
