What’s Problematic About Hard Water?

How Can I Prevent Hard Water Stains on Granite?
We’re not meaning to be patronizing here, but the easiest way to prevent hard water stains on granite is to keep it dry. This is especially important around the faucet where water can leak and dry out without being readily noticed.
Be careful to clean up after doing dishes or scrubbing out pots and pans, and if you use a drip tray for drying dishes be sure to keep the area under and around it dry and clean. Consider putting a fluffy microfiber towel under your drip tray to absorb hard water, and be sure to check this area often for stains.
The same toweling material is useful for drying inverted glasses and mugs and will help keep your granite dry, beautiful, and stain-free. If you wash down your countertops with tap water, dry them thoroughly.
You may also wish to invest in a point-of-entry water softener device to eliminate hard water stains at the source. This will be costly but will solve the problem of hard water in the kitchen as well as the restroom. So will hard water ruin granite completely? What’s the worst that it can do?
Will Hard Water Ruin Granite?
If your granite is sealed, this will offer it some protection from hard water, and other damages. The seal is a compound that sprays on and offers good protection from moisture and stains.
Granite is pretty tough, but as a stone, it’s still porous and can absorb water. This absorbed water can cause damage eventually, and granite can also absorb problematic ingredients like turmeric powder which can ruin countertops, even if sealed. The lighter colored your granite is, the worse it will look when stained.
Hard water will typically not ruin countertops, but the longer you allow a stain to hang around, the tougher it will be to remove. Intense scrubbing at these stains can damage granite, and some harsh cleaning agents can ruin granite, too. Which cleaning agents should you not use on your granite countertops?
Can I Use Harsh Cleansers on Granite?
Granite is a pretty tough rock, but some household cleaning products can not be used with granite. You’ll want to avoid anything bleach-rich or acidic, and this includes common household cleaners like Comet and Bar Keeper’s Friend. They’re great products, but they’re just too harsh for granite.
What about CLR? The problem with CLR is that it contains an acidic ingredient that eats away at calcium and lime but can also damage stone. Even though CLR is designed to remove hard water stains, make sure it’s used only on metal, not on or even near granite. Granite cleaners should be closer to a neutral 7 in pH level, and you’ll also want to avoid vinegar, lemon juice, lime juice, and Windex.
Granite holds up pretty well to scratches, even scratches from knives. That doesn’t mean you’ll want to put that density to the test, though. Avoid extra-rough products like steel wool, and stick to softer cloth materials that can absorb moisture and rub in polish without causing damage.
Hard water stains on granite countertops can be removed with a mix of baking soda, water, and gentle scrubbing. These hard water stains are typically cosmetic but can damage granite if not immediately cleaned up. The harsh scrubbing that it takes to remove stubborn hard water stains can also cause damage to countertops.
Make sure to dry up any water that does pool, especially near faucets and sinks. Protect countertops with absorbent microfiber towels near drip trays, and allow dishes and glasses to dry on top of a soft surface or mat, not directly on the granite surface. Finally, avoid harsh cleansers like Comet and CLR, as these can seriously damage granite and granite seals.
