1. Blade and Granite Cleaner – For Tenacious Stains

If you have strong stains on your countertop or water rings around the faucet from water that stays on the surface, use a designated granite cleaner that you can quickly find in your nearby supermarket or grocery store. Be mindful, however, that granite cleaner is a harsh chemical so make sure to protect your hand with safety gloves before beginning the process.

After applying the granite cleaner, use the sharp razor to gradually scrape away the hard deposits on the solid stains. Make sure not to use the blade too forcefully as it can scratch and lead to unwanted damage on your granite.

After removing the hard mineral particle, you can now use a soft cloth to clear them away. Put granite cleaner again on the stain and use a clean sponge to touch all the areas. Let the liquid stay depending on the instructions given on the product’s label. Then, wipe it again using the cloth and you will notice the stain vanishing. However, if the granite cleaner is unable to clear the stain fully, you can switch to stronger chemicals, such as muriatic acid.

2. Baking Soda – For Stubborn Stains

While basic in nature, baking soda can be effective in sucking up the hard water stains from your granite countertop. Make sure to wet the stains and blot it first. Then, make a baking soda paste by mixing it water. See to it to gauge how much water you’ll be putting or somewhat enough to form a thick paste.

Next, apply the paste on the stains, top it up with plastic and leave it for 24 hours. The baking soda paste will do its magic on the stain. Wash the spot with gentle soap and water to fully remove the leftover marks on your countertop.

3. Denatured Alcohol – For The Same Stubborn Stains

For the same stubborn stains, another way to get rid of them and restore your granite countertops lost glory is by cleaning them using denatured alcohol. Just simply mix three parts of water, one part of denatured alcohol then put a few drops of dishwashing liquid.

Apply this liquid on the solid marks and use a clean cloth to rub the stains in a circular motion. Make sure to change the sides of the cloth from time to time. Continue repeating the steps until the stain clears away or until you get a shiny surface.

What’s great is that you can put the mixture in a spray bottle and use it for the regular cleaning of your countertop. See to it, however, to pick a dishwashing liquid that is pH neutral. Any acidic product can react negatively with your granite and lead to etching on its surface.

4. White Vinegar – For Slightly Stubborn Stains

For slightly stubborn stains, white vinegar can be your best ally in defeating them. White vinegar is preferred than normal vinegar as it is much less acidic and won’t cause any etching on your granite’s countertops. Take some paper towels and use them to cover the solid water stains. Once done, wet the paper towels with white vinegar drop and let them soak for over 30 minutes.

After 30 minutes, remove the paper towels. Using a soft scrubber, remove all the leftover stain in the area. See to it, however, that the paper towels won’t dry up on the surface while waiting for it to soak up all the stains. If it, unfortunately, dries up, it can lead to further mark on your granite. Extra caution is needed for this method.

Prevention Tips

While it may seem easy to get rid of hard water stains from your granite countertops, cleaning any stain as soon as you see them will mean less effort and time in the long run. Moreover, you also save up on the cost of having to buy products to remove these solid marks. Often times, what you deem as a water stain might also be only a soap deposit, which you can wipe off easily.

If you see light water stains around your basin or sink, make to sure clean them off immediately. Get a brush with soft bristles (an old toothbrush will suffice). Then, put water and detergent on the stain and scrub it using the brush. This procedure will help lift the mineral deposits and clear them away. Once finished, rinse the area with clean water and dry it with a cloth or towel.

Alternatively, you could use the denatured alcohol mixture you’ve made as an everyday cleaner, let it sit on any early stain you see to loosen the minerals. Then, scrub it again using the brush, and rinse and dry once the stain fades away.

Protect The Sealant

You may not be aware but the granite has a sealant on the surface of the stone. While the granite itself is tough and durable, the sealant is quite vulnerable. It is critical not to damage it at any cause as it can be porous. Doing so will cause it to stain easier and having the actual stone compromised. With that, it is your best to protect the sealant from any damage. 

Never ever use acidic cleaners or even natural ones like lemon juice or normal vinegar. They have harsh elements that can damage the sealant. Moreover, avoid using steel wool or other extra hard cleaning materials to avoid scratching the surface.

Also, don’t forget to reseal your granite every few years. This should be a part of your regular maintenance to keep your countertop’s condition. To check if the sealant is starting to wear, put a drop of water on the surface of your granite. If the water droplet stays, you’re good as the sealant is still well-working. However, if it soaks in, then, it needs replacing.
