How to Clean and Maintain Natural Stone Countertops: Marble, Granite & Quartz Care Guide

Stone countertops are one of the most popular upgrades in kitchens and bathrooms today. Marble, granite, and quartz all bring a polished, high-end look to a home. But here’s what a lot of homeowners don’t realize: each of these materials needs a different cleaning approach. Use the wrong product, and you can permanently etch, stain, or dull a surface that’s supposed to last a lifetime.

So, before you reach for whatever cleaner is under the sink, it’s worth understanding what your specific countertop actually needs. This guide breaks down the right way to clean marble, granite, and quartz, the mistakes to avoid, and how often each material needs deeper maintenance.

Why Countertop Material Matters for Cleaning

Not all stone is created equal. Marble and granite are natural stone, which means they’re porous to varying degrees. That porosity is exactly why they need sealing, and why acidic substances can damage them so easily. Quartz, on the other hand, is engineered. It’s made from crushed stone bound with resin, which makes it non-porous and far more forgiving day to day.

Because of these differences, a cleaning product that’s perfectly safe for one countertop can quietly damage another. Marble, for example, reacts badly to the same acidic cleaners that granite can usually tolerate. So, knowing your material is the first step to caring for it properly.

Not Sure What Material Your Countertop Is?

This happens more often than you’d think, especially in homes that changed owners or went through a renovation before you moved in. A few quick checks can help. Marble tends to have soft, flowing veining and feels cool and slightly porous to the touch. Granite usually shows a more speckled, grainy pattern with visible mineral flecks. Quartz, since it’s engineered, often has a more uniform, consistent pattern with less natural variation.

If you’re still unsure, a simple test can help. Place a drop of water on the surface. Natural stone, like marble or granite, will usually absorb it within a few minutes if the seal has worn down. Quartz, being non-porous, won’t absorb water at all, no matter how long it sits. When in doubt, a professional cleaner or the original installer can usually identify the material on sight.

How to Clean Marble Countertops

Marble is beautiful, but it’s also the most sensitive of the three materials. It’s highly porous and very reactive to acid. That means everyday items like lemon juice, vinegar, wine, and even some fruit juices can etch the surface on contact, leaving a dull mark that doesn’t wipe away.

• Clean with warm water and a pH-neutral soap, applied with a soft cloth
• Wipe up spills immediately, especially anything acidic like citrus, coffee, or wine
• Avoid vinegar, bleach, and any cleaner labeled as acidic, even natural ones
• Skip abrasive sponges or scouring pads, which can scratch the polished finish
• Reseal the surface every 6 to 12 months to maintain its resistance to stains

If you already have an etch mark, a marble-specific polishing product can sometimes reduce its appearance. For deeper damage, professional restoration is usually the better option rather than attempting a DIY fix.

How to Clean Granite Countertops

Granite is more forgiving than marble, but it still needs consistent care. It’s also porous, just less reactive to acid than marble is. Without proper sealing, though, it can still absorb oils, wine, and other liquids over time, leading to stains that are hard to remove.

• Clean daily with warm water and a mild dish soap
• Avoid ammonia and bleach-based cleaners, which can wear down the sealant over time
• Use cutting boards and trivets to prevent scratches and heat marks
• Reseal annually, or sooner if water no longer beads on the surface
• Dry the counter after cleaning to prevent water spots and mineral buildup

A simple way to check if your granite needs resealing is the water test. Just place a few drops of water on the surface. If it beads up, the seal is still doing its job. If it soaks in within a minute or two, it’s time to reseal.

How to Clean Quartz Countertops

Quartz is the most low-maintenance of the three. Because it’s engineered and non-porous, it doesn’t need sealing at all, and it resists staining far better than natural stone. That said, it’s not indestructible, and a few habits can still shorten its lifespan.

• Wipe down daily with warm water and a mild soap
• Avoid bleach and other harsh chemicals, which can discolor the surface over time
• Keep hot pans and dishes off the surface directly, since high heat can damage the resin
• Skip abrasive cleaners or pads, even though quartz is more scratch-resistant than marble

Because quartz doesn’t require sealing, maintenance mostly comes down to consistent, gentle cleaning rather than periodic treatments.

Common Countertop Cleaning Mistakes to Avoid

• Using vinegar or citrus-based cleaners on marble or granite
• Scrubbing with steel wool or abrasive pads on any stone surface
• Skipping the sealing schedule for marble and granite
• Placing hot pans directly on the countertop, regardless of material
• Letting spills sit for hours instead of wiping them up right away

Most countertop damage doesn’t happen all at once. Instead, it builds up slowly from small habits repeated over months or years. A single splash of lemon juice on marble might not seem like a big deal in the moment, but repeated over dozens of small incidents, those tiny etch marks add up into a countertop that looks noticeably duller than it did on installation day. So, catching these mistakes early is often the difference between a countertop that looks great for decades and one that needs replacing far sooner than it should.

It’s also worth mentioning cleaning wipes. Many all-purpose disinfecting wipes contain citric acid or other mild acids as part of their formula. They’re convenient, but they’re not always safe for marble or unsealed granite. Checking the label before grabbing whatever wipe is closest can save you from an unpleasant surprise later.

How Professional Cleaning Helps Maintain Stone Countertops

Even with the best intentions, it’s easy to grab the wrong product on a busy day. A professional cleaning team already knows which cleaners are safe for marble, which ones work on granite, and which ones quartz can handle without issue.

Beyond the products themselves, regular professional cleaning also means someone is consistently checking on the condition of your surfaces. That makes it far easier to catch early signs of dullness, staining, or a failing seal, before they turn into permanent damage.

Frequently Asked Questions

Can I use regular dish soap on granite or marble?
Yes, as long as it’s a mild, non-acidic dish soap. Avoid anything labeled as a degreaser or citrus-based cleaner, since those can be too harsh for natural stone over time.

How do I know if my countertop needs resealing?
Try the water test. Place a few drops of water on the surface. If it beads up, the seal is still working. If it soaks in quickly, it’s time to reseal.

Will professional cleaning include sealing my countertops?
Standard cleaning visits typically don’t include sealing, since that’s a separate, specialized service. However, our team can flag when a surface looks like it needs resealing soon.

What should I do if I already have a stain or etch mark?
For minor marks, a stone-specific polishing product can sometimes help. For deeper stains or etching, professional stone restoration is usually a better long-term fix than a DIY attempt.

Are cleaning wipes safe to use on stone countertops?
It depends on the wipe. Many disinfecting wipes contain mild acids that are fine for quartz but risky for marble or unsealed granite. Checking the label, or sticking to a dedicated stone-safe cleaner, is the safer choice.
