It’s one of the most common questions when choosing natural stone, especially for a kitchen: will it stain?
The answer is that natural stone can stain, but how easily depends on the type of stone, how well it’s sealed and how you care for it.
The good news? A few simple habits can make a big difference.
Marble, Dolomite & Quartzite: What’s the Difference?
Not all natural stone behaves the same way.
Marble is generally more porous and needs a little more care. Because it is calcite-based, acidic products like lemon juice and vinegar can cause etching, which appears as a dull mark on the surface.
Dolomite is generally harder than marble, but it can still be sensitive to acids and should be properly sealed.
Quartzite is typically harder and more resistant to scratching and acids. However, quartzite can still absorb liquids, so sealing is still important.
Whichever stone you choose, understanding how it behaves will make it much easier to care for.
Why Is Sealing Important?
Sealing is one of the best ways to help protect natural stone from staining.
A penetrating sealer reduces how quickly liquids absorb into the stone, giving you more time to wipe up coffee, wine, oils and everyday spills.
But remember: sealed doesn’t mean stain-proof.
How often your stone needs sealing depends on the stone, its finish, the sealer used and how heavily the surface is used.
Rather than automatically resealing every year, check your stone periodically. If water begins absorbing or darkening the surface more quickly than it used to, it may be time to have the sealer checked or reapplied.
Your stonemason or stone-care professional can advise on what’s suitable for your particular stone.
The Do’s & Don’ts
DO
- Wipe up spills sooner rather than later.
- Use a pH-neutral cleaner made for natural stone.
- Use chopping boards, coasters and trays.
- Check your stone periodically to see if it needs resealing.
- Be extra mindful of oils, wine and strongly coloured liquids.
DON’T
- Use vinegar, lemon or acidic cleaners on marble or dolomite.
- Assume sealed stone can’t stain.
- Leave spills sitting for long periods.
- Use harsh chemicals or abrasive cleaning pads.
- Try random DIY stain removers without checking they’re safe for your stone.
A Little Care Goes a Long Way
Natural stone doesn’t need to be difficult to live with.
Marble requires a little more care, dolomite offers its own balance of characteristics, and quartzite is generally more resistant. No matter which you choose, proper sealing and simple everyday care will help keep it looking beautiful.
The key is understanding your stone, looking after it properly and then enjoying it as part of your home.
