How do I clean stubborn stains from granite slabs?
Dec 16, 2025
Hey there! As a supplier of top - notch granite slabs, I've heard all sorts of questions from customers, and one that pops up a lot is how to clean stubborn stains from granite slabs. Well, you're in the right place! I'm gonna share some tried - and - true methods to get your granite looking brand new again.
First off, let's talk a bit about granite. It's a natural stone, and while it's super durable, it's also porous. That means it can absorb liquids and get stained if not properly maintained. But don't worry, with the right approach, you can handle those tough stains.
Common Types of Stains and How to Identify Them
Before you start cleaning, it's important to know what kind of stain you're dealing with. Different stains require different cleaning methods.
Oil - Based Stains
These are probably the most common type of stains on granite slabs. They can come from cooking oils, grease, or even some cosmetics. Oil - based stains usually look dark and can seep deep into the granite. If you notice a spot that looks darker than the surrounding area and seems to be a bit sticky or greasy to the touch, chances are it's an oil - based stain.
Water - Based Stains
Water - based stains are often caused by spills like coffee, tea, or juice. They tend to be lighter in color and may leave a discolored ring on the granite. If you spill a liquid and don't clean it up right away, it can soak into the stone and leave a stain.


Rust Stains
Rust stains are a bit trickier. They usually come from metal objects that have been left on the granite for too long, like a wet knife or a metal pan. Rust stains look orange or brown and can be pretty stubborn.
Cleaning Methods for Different Stains
Oil - Based Stains
For oil - based stains, you'll need an absorbent material and a cleaning agent. Start by sprinkling baking soda or cornstarch on the stain. These substances are great at absorbing oil. Let it sit for a few hours or even overnight if the stain is really bad. Then, use a soft brush to gently scrub the area. After that, mix a mild dish soap with warm water. Dip a clean cloth into the soapy water and wipe the area. Rinse with clean water and dry with a soft towel.
If the stain is still there, you can try using a commercial granite cleaner. Make sure to follow the instructions on the label.

Water - Based Stains
To clean water - based stains, you can start with a simple mixture of vinegar and water. Mix equal parts of white vinegar and water in a spray bottle. Spray the solution on the stain and let it sit for a few minutes. Then, use a soft cloth to wipe the area. If the stain is still visible, you can make a paste of baking soda and water. Apply the paste to the stain, cover it with plastic wrap, and let it sit for a few hours. After that, remove the plastic wrap and gently scrub the area with a soft brush. Rinse with water and dry. This method works wonders for Wave White Granite Slabs that might have water - based stains. You can explore more about Wave White Granite Slabs on our website.
Rust Stains
Rust stains are a bit more difficult to remove. You can try using a rust remover specifically designed for granite. Make sure to test it on a small, inconspicuous area first to make sure it doesn't damage the granite. Apply the rust remover according to the instructions on the label. Let it sit for the recommended time, then scrub the area gently with a soft brush. Rinse thoroughly with water and dry. Cosmic Black Granite Slabs are also prone to rust stains in some cases.

Preventive Measures
Of course, the best way to deal with stains is to prevent them from happening in the first place. Here are some tips:
- Seal your granite slabs regularly. A good sealant creates a protective barrier that prevents liquids from soaking into the stone. You should seal your granite at least once a year, or more often if it's in a high - traffic area.
- Wipe up spills immediately. Don't let liquids sit on the granite for too long. Use a clean cloth or paper towel to blot the spill as soon as it happens.
- Use coasters and placemats. When you're using glasses, cups, or hot pans on the granite, use coasters and placemats to protect the surface.
Conclusion
Cleaning stubborn stains from granite slabs might seem like a daunting task, but with the right knowledge and methods, it's definitely doable. Whether you're dealing with oil - based, water - based, or rust stains, there are solutions out there. And remember, prevention is key.
