Marble and natural stone countertops are beautiful but need care. Learn how to clean, seal, and maintain them with products I actually use.

How to Care for a Marble or Natural Stone Countertop

I love natural stone countertops, and honestly, I think they’re often worth the splurge. There’s just something about real stone that adds character, depth, and a lived-in beauty you can’t quite replicate. That said… marble and natural stone do require a little extra maintenance, so it’s important to know what you’re getting into before you install them.

If you already have marble or stone countertops (or you’re considering them), there are a few key things you’ll want to take into account to keep them looking beautiful for years to come.

Our Real-Life Stone Countertops

We’ve used natural stone throughout our home in a few different ways:

• In our laundry room and on the bar top in our TV room, we have Black Diamond quartzite
• In our green bathroom, we chose a Carrara marble countertop
• In our garage apartment kitchenette, we installed Mont Blanc quartzite

Each stone has its own personality, but they all share similar care needs, and that’s where sealing and cleaning really matter.

Marble & Natural Stone Are Porous (Yes, Even Quartzite)

One of the most important things to understand is that marble and natural stone are porous. That means they can absorb liquids, which can lead to stains or etching if they’re not properly protected.

Seal Your Countertops

Sealing helps create a protective barrier and is a must for stone countertops. Depending on the stone and how much use it gets, sealing may need to be done once or twice a year.

Your countertop installers should seal the countertop for you initially after install with a professional grade sealer. This can last 1 to 5 years depending on the stone type, countertop usage, and sealer quality. Most professionals recommend resealing every 1 to 2 years for optimal protection.

Sealer I’ve used

If you’re unsure which sealer is best, your countertop supplier is a great resource and can usually recommend something specific to your stone.

Use the Right Cleaner (This Matters!)

Harsh or acidic cleaners can damage natural stone—especially marble. Skip the all-purpose sprays and anything with vinegar, bleach, or ammonia. Instead, use a cleaner specifically made for stone countertops.

Stone cleaner I’ve used

A good stone cleaner will gently clean without stripping the sealer or dulling the surface.

Daily Habits That Help Protect Stone

A few simple habits go a long way:

• Wipe up spills quickly (especially dark colors, coffee, and citrus)
• Use coasters and trays when possible
• Avoid placing hot items directly on the surface (there are exceptions depending on the type of stone)
• Use cutting boards. Stone can dull knives and scratch

Stone countertops are durable, but they appreciate a little care.

A Quick Note About Quartz vs. Natural Stone

Side note: We opted for quartz countertops in our kitchen because of the size of the space and to stay within our budget. Quartz is more affordable and much easier to maintain, which made sense for a high-use area.

That said… I still kind of regret not spending a bit more and going with quartzite, which was my first choice. Natural stone just has a depth and variation that I truly love.

Is Marble or Natural Stone Worth It?

In my opinion—yes, in many cases. If you’re okay with a little extra maintenance and you love the look of natural materials, marble and quartzite can be absolutely stunning and timeless.

As long as you go in knowing how to care for them, they can be a beautiful (and totally worthwhile) investment in your home.

FAQs

How often should marble or natural stone countertops be sealed?

Most marble and natural stone countertops should be sealed once or twice a year, depending on how much use they get. High-traffic areas like kitchens and bars may need more frequent sealing.

What is the best cleaner for marble countertops?

The best cleaner for marble countertops is a stone-specific, pH-neutral cleaner. Avoid vinegar, bleach, ammonia, or harsh chemicals, as they can damage and dull the stone.

Can marble countertops stain easily?

Yes, marble can stain because it is porous. Spills like wine, coffee, or citrus juice should be wiped up quickly, and sealing helps protect the surface from absorbing liquids.

Is quartzite easier to maintain than marble?

Quartzite is generally more durable and slightly more stain-resistant than marble, but it is still a natural stone and requires sealing and proper care.

Can I use vinegar or household cleaners on stone countertops?

No. Vinegar and many household cleaners are acidic and can etch or damage marble and natural stone. Always use cleaners made specifically for stone surfaces.

What is the difference between marble, quartzite, and quartz countertops?

Marble and quartzite are natural stone and require sealing and gentle cleaners. Quartz is engineered, non-porous, and easier to maintain, but does not have the same natural variation as stone.

Are natural stone countertops worth the extra maintenance?

For many homeowners, yes. Natural stone countertops offer timeless beauty and unique character. As long as you understand the maintenance involved, they can be a worthwhile investment.

Can heat damage marble or quartzite countertops?

Yes. While stone is heat-resistant, placing hot pans directly on the surface can cause damage over time. It’s best to use trivets or heat pads.
