Quartzite is one of the most durable natural stones available, but homeowners often worry about staining—especially from cooking oils like olive oil. While quartzite is highly resistant to heat and everyday wear, oils can still leave marks if they sit on the surface too long.
Here’s what you need to know about olive oil and quartzite, and how to prevent and remove oil stains effectively.
Can Olive Oil Stain Quartzite?
Yes, olive oil can stain quartzite, but it usually only happens if:
-
The countertop isn’t sealed
-
The sealer is old or worn
-
The oil sits on the surface for a long time
-
The quartzite is particularly porous in certain areas
Quartzite is a natural stone, and some slabs have tiny pores that can absorb oils. When olive oil penetrates these pores, it darkens the area and leaves an oily spot.
Why Oil Stains Happen on Quartzite
Quartzite is harder and denser than marble, but it’s not completely non-porous. Oils behave differently from water—they seep deeper and don’t evaporate easily, which is why oil stains can linger.
A properly applied sealer acts as a barrier that slows down absorption. When the sealer is wearing off, oils can soak in more easily.
How to Get Olive Oil Off Quartzite
If you catch the spill early, cleaning is simple:
1. Wipe Immediately
Use a dry paper towel or microfiber cloth to blot—not smear—the oil.
2. Clean With a Degreasing, Stone-Safe Cleaner
A pH-neutral stone cleaner designed for oil removal works best.
How to Remove a Deep Olive Oil Stain
If the oil has already soaked in and left a dark spot, use a poultice. A poultice pulls the oil out of the stone.
DIY Poultice Recipe
-
Baking soda
-
A small amount of water (to make a paste)
Spread the paste over the stain, cover it with plastic wrap, and tape the edges. Let it sit for 24–48 hours, then wipe it off.
Commercial oil-removal poultices also work well and may be faster.
Does Olive Oil Damage Quartzite?
No—olive oil does not damage the stone structurally. It only causes temporary discoloration. With the right cleaning or a poultice, quartzite will return to normal.
How to Prevent Oil Stains on Quartzite
-
Wipe spills immediately
-
Reseal quartzite every 6–12 months (depending on usage)
-
Use cutting boards and drip trays when cooking
-
Choose a high-quality penetrating sealer
A good sealer is your best defense against stains of any kind, including oil.
Final Thoughts
Olive oil can stain quartzite if left to sit, but the stains are usually removable and not permanent. With proper sealing and quick cleanup habits, quartzite surfaces remain beautiful, durable, and resistant to everyday kitchen spills.
