Granite is a popular choice for countertops because of its durability and natural beauty. However, one common issue homeowners face is the buildup of limescale—those stubborn white, chalky spots caused by hard water.
If you’ve noticed limescale on your granite, you might wonder how to remove it, without damaging the stone. Luckily, there are safe, effective methods to remove limescale from granite—ensuring they look as good as new. Read on to find out!
What Causes Limescale Buildup on Granite?
Limescale is a buildup of mineral deposits, primarily calcium carbonate, that occurs when hard water evaporates and leaves these minerals behind.
While limescale is most commonly associated with bathroom fixtures, it can also form on granite countertops, especially around sinks, faucets, and areas that frequently come into contact with water.
Over time, limescale not only dulls the shine of your granite but can also be tricky to remove if left untreated.
The good news? You can tackle limescale without causing any harm to your granite if you use the right techniques and products.

Tools and Materials You’ll Need
Before diving into the process, gather the following items to ensure you can remove limescale safely:
- Soft cloth or sponge: Essential for applying cleaning solutions and gently scrubbing the granite.
- Microfiber towel: To dry the surface after cleaning and avoid water spots.
- White vinegar or granite-safe cleaner: Vinegar works well for limescale but must be diluted to avoid damaging the granite. A granite-safe cleaner is another excellent option.
- Non-abrasive brush or nylon scrubber: For areas that need a bit of extra scrubbing without scratching the surface.
- Plastic scraper (optional): For tough limescale spots that don’t come off easily.
- Granite polish (optional): To restore the shine after cleaning.
Proven Steps to Safely Remove Limescale from Granite
Now that you’re prepared, let’s get into how to remove limescale from your granite surfaces safely and effectively.
Step#1 Prepare the Granite Surface
The first thing you need to do is clear the countertop or granite surface. Remove any items that could get in the way, such as soap dispensers, cutting boards, or dishes.
Next, wipe down the surface with a soft, dry cloth to remove any loose debris or dust. This will make the limescale easier to target.
Step#2 Apply a Granite-Safe Cleaning Solution
The safest and most common solution for tackling limescale is a 50/50 mixture of white vinegar and water. Vinegar naturally dissolves mineral deposits, making it a great option. However, because granite is a natural stone that can be sensitive to acidic substances, it’s essential to dilute the vinegar.
Alternatively, you can use a granite-safe cleaner specifically formulated to break down hard water deposits without damaging the surface.
Apply the solution to the limescale-affected areas, making sure the spots are well covered, and let it sit for 5-10 minutes. This allows the solution to penetrate the mineral buildup and loosen it for easier removal.
Step#3 Gently Scrub the Limescale
Once the solution has had time to work, take a non-abrasive brush or nylon scrubber and gently scrub the limescale.
The key here is to be gentle—granite can scratch if you use too much pressure or an abrasive tool. Work in circular motions, focusing on the areas where the limescale is most prominent.
If you’re concerned about scratching your granite, you can also use a soft cloth or sponge, although this might take a little more effort on stubborn spots.
Step#4 Rinse and Wipe the Surface
After scrubbing, it’s time to rinse off the solution. Dampen a soft cloth with water and thoroughly wipe the granite to remove any remaining cleaner and loosened limescale.
Once the area is clean, dry it immediately with a microfiber towel. This step is crucial because leaving water on the granite can lead to more limescale buildup.
Step#5 Use a Plastic Scraper for Stubborn Limescale (Optional)
If you still see some tough spots that won’t budge, don’t worry! You can use a plastic scraper to gently lift the remaining limescale.
Hence, be sure to avoid metal scrapers, as these can damage the granite. Gently glide the plastic scraper along the surface, applying minimal pressure to remove any lingering deposits.
Preventing Limescale Buildup on Granite
Now that you’ve successfully removed the limescale, it’s important to keep your granite looking great. Below are some tips to prevent future limescale buildup:
Wipe Down Surfaces Regularly: After using the sink or cleaning up spills, make it a habit to wipe down your granite countertops with a dry cloth. This prevents hard water from sitting on the surface and forming limescale.
Use a Water Softener: If hard water is a recurring issue, installing a water softener can reduce the amount of minerals in the water, effectively preventing limescale.
Seal Your Granite: Granite is porous, so applying a granite sealer every 6-12 months helps protect the surface from absorbing water and developing limescale. A sealed surface also makes cleaning easier and preserves the stone’s natural shine.
Safe Cleaning Products for Granite Surfaces
When it comes to cleaning granite, it’s essential to use products that are specifically designed for natural stone.
Avoid harsh chemicals, abrasives, or any cleaners that contain bleach, ammonia, or acidic ingredients like lemon juice. These can etch the surface of your granite, leaving dull spots or even permanent damage.
Here are some safe options:
Granite-safe cleaners: Many commercial cleaners are formulated to tackle hard water and limescale while protecting natural stone.
pH-neutral cleaners: These are gentle enough for regular cleaning without harming your granite.
White vinegar (Diluted): As mentioned earlier, vinegar can be an effective natural solution when diluted, but it should be used sparingly and rinsed off thoroughly.
Concluding Words
Removing limescale from granite doesn’t have to be a complicated task, especially if you use the right tools and methods.
However, by following the above-mentioned steps, you can safely clean your granite surfaces and restore their natural beauty without risking damage.
