Quartz countertops are renowned for their durability, aesthetics, and low maintenance. But despite their stellar reputation, many homeowners still wonder – do quartz countertops stain? The short answer is yes, quartz can stain. However, quartz is far more stain-resistant than other natural stone countertops like granite or marble. With proper care and maintenance, quartz countertops can remain stain-free for many years. This article will provide an in-depth look at the stain resistance of quartz, what can cause stains, and how to prevent and remove them.
What Is Quartz?
Before diving into stains, let’s first understand what quartz countertops are made of. Quartz is an engineered stone, made from crushed quartz particles combined with pigments and resin. The quartz content typically ranges from 90-94%, with the rest being polymer resins that bind the material together.
The resin makes quartz non-porous, so it does not require sealing like natural stone. The lack of pores and high quartz content make quartz very durable and resistant to scratches, impacts, and heat. Quartz hardness registers at 7 on the Mohs scale, compared to 4 for granite. All of these features make quartz an ideal material for kitchen and bathroom countertops.
Is Quartz Stain Proof?
The quick answer is no. Although quartz has excellent stain resistance, it is not completely stain-proof. When quartz first became popular over two decades ago, some manufacturers marketed it as “maintenance free” and “stain proof”. But this led to unrealistic expectations among consumers.
Over time it became clear that stains could occur on quartz surfaces. However, quartz is still far more stain-resistant than marble, granite, concrete, laminate, or wood countertops. The non-porous nature of quartz makes it unlikely for stains to penetrate deep into the material. Most stains remain on the surface and can be removed with the proper cleaning methods.
What Can Stain Quartz Countertops?
Although rare, quartz can become stained by certain substances if left on the surface for too long. Here are some of the most common culprits:
Oils and Grease
Food oils and greases, if not wiped up promptly, can stain quartz. Vegetable oil, olive oil, bacon grease and butter are examples of kitchen stains that require quick cleanup. The longer the oil sits, the darker the stain can become as it oxidizes on the surface.
Beverages like wine, coffee, tea, juice and soda contain pigments that can stain. Allowing dark liquids to pool or dry on the countertop leaves a stubborn stain. Acidic drinks like juice, wine or soda have more staining potential.
Foods and Spices
Foods with strong pigments can discolor quartz if left for too long. These include mustard, ketchup, curry powder, turmeric and citrus fruits. Berries, beets and pomegranate juice are other problematic foods.
Ink and Dye Stains
Ink from pens and markers will stain if not wiped up quickly. Hair dye, makeup with pigments, and fabric dye transfer from clothes are other staining risks. Using quartz near art studios or craft areas raises the odds of ink and dye stains occurring.
Hard Water Stains
Mineral deposits in hard water can leave etching or staining on quartz. Tap water allowed to dry on counter edges or around sinks can leave cloudy, whitish mineral stains.
Iron leaching from pots, pans or metal utensils can cause orange/brown stains on quartz. Steel wool pads also pose a rust stain risk.
How to Prevent Quartz Stains
Prevention is the best solution to keep quartz stain-free for years. Follow these tips to avoid stains:
- Wipe up spills immediately, especially oils, wine and other pigmented liquids. Don’t let anything sit on quartz for over 10 minutes.
- Use cutting boards and trivets. Never cut directly on quartz or place hot pots/pans on the surface.
- Clean with a gentle stone cleaner after food prep. Use a microfiber cloth to remove all residues.
- Avoid exposure to inks, dyes and rust-prone objects. Keep quartz away from art studios and craft areas.
- Seal and re-seal granite, marble or concrete near your quartz. Their porosity can cause transfer stains.
- Check for metal marks or rust spots after using pots, pans or metal tools. Remove any residues left behind.
- Use placemats under serving ware that can leave marks. Ceramic, silver and crystal serving pieces pose a risk.
- Spot-clean often with a quartz-safe cleaner to prevent buildup of oils, soap scum or hard water.
- Consider applying a stain-resistant sealer to quartz in high traffic kitchens. Sealers provide added protection.
Following these precautions will minimize the opportunities for stains to occur. But even with great care, stains can still happen occasionally.
How to Remove Stains from Quartz Countertops
If a stain occurs on your quartz, don’t panic. Most stains can be removed with the right techniques and cleaning products. Here are steps for removing common quartz stains:
Step 1: Try Gentle Cleaners First
For fresh stains under 24 hours old, start with a gentle stone cleaner. Spray the stain, let sit 5 minutes, and scrub with a soft cloth or sponge. Avoid abrasive scouring pads. If needed, repeat the process 2-3 times. This may lift many fresh stains.
Step 2: Use a Poultice for Stubborn Stains
If gentle cleaners fail, make a poultice to draw out the stain. A poultice is a thick paste made with an absorbent powder like talc or baking soda, mixed with hydrogen peroxide or stone cleaner. Apply a 1⁄4 inch layer over the stain, cover in plastic wrap, and let sit for 24 hours. This helps pull the stain out from the surface.
Step 3: Try Mild Solvents for Oils and Dyes
For grease, oil or dye stains that remain, carefully try a mild solvent like isopropyl alcohol, acetone, or mineral spirits. Test first in an inconspicuous spot to ensure the quartz color is not affected. Apply a small amount to a cloth and gently rub the stain. Repeat if needed, rinsing thoroughly. Harsh solvents like lacquer thinner or MEK can dull quartz’s shine.
Step 4: Use an Alkaline Cleaner for Stubborn Issues
For extremely stubborn stains, an alkaline cleaner like diluted ammonia, baking soda paste, or alkaline tile cleaner may be required. Exercise caution with alkaline cleaners – only use if other methods fail. Rinse thoroughly after use.
Step 5: Lightly Sand Severe Stains
In rare cases of deep, permanent staining, very light sanding may be the only option. Use fine 400+ grit sandpaper and minimal pressure. This is a last resort, as sanding will dull the finish. A professional may need to resurface the sanded area after staining is removed.
Step 6: Re-seal and Re-polish
After staining is removed, re-seal the quartz with a penetrating sealer recommended by your installer. This prevents future stains. Finish by re-polishing the surface if needed to restore the quartz’s shine.
Will Quartz Stain with Time and Use?
Quartz has outstanding longevity if properly cared for. Ten or fifteen years down the road, quartz will not become more stain-prone with age. Nor will the color change or fade out significantly.
However, the glossy polished finish can gradually dull in high traffic areas. Over time, etching from acidic foods and drinks can also dull quartz’s shine. But these effects are superficial and do not impact stain resistance. With periodic re-polishing, quartz easily restores its original sparkling finish.
Proper maintenance is key. Follow the cleaning best practices, treat stains promptly, and get surfaces re-polished every 3-5 years. With this care, quartz countertops will stay looking like new for decades.
Signs Your Quartz Needs Professional Help
In most cases, homeowners can remove stains successfully on their own. But some situations call for professional help:
- Severe staining across large areas of the countertop
- Stains that reappear shortly after removing them
- Permanent dyes/inks thatcannot be extracted after multiple attempts
- Etching damage from prolonged exposure to acids
- A need to resurface large scratched or dulled areas
- Restoration of the glossy finish after years of use
Seek reputable quartz fabricators or stone restoration experts if your stains prove difficult. They have specialized tools, chemicals and training to revitalize badly stained quartz.
Can You Remove All Stains from Quartz?
With the right techniques, most stains can be removed from quartz completely. Light stains often come out with gentle stone cleaners. Poultices, solvents and alkaline cleaners can lift more stubborn issues.
However, some permanent stains may not budge if:
- The stain was allowed to set for a very long time before attempting removal
- An overly harsh chemical permanently discolored or etched the surface
- Dye penetrated deep due to porous cracks/fissures in the quartz
- The stain underwent a chemical reaction with quartz minerals
Avoid using bleach or harsh chemicals that will make stains harder to remove. Get professional help quickly for severe staining situations.

Quartz Stain FAQs
Homeowners often have these common questions about quartz stains:
Does Quartz Stain Easily?
No, quartz does not stain easily. The non-porous material makes it very resistant to staining. Most spills and residues rinse off with just soap and water. Stains only occur if a staining agent is left on the surface for an extended time. With prompt cleanup of spills, stains are unlikely.
Do Coffee and Wine Stain Quartz?
Coffee and wine can stain quartz if allowed to sit for hours and dry on the surface. The pigments in these drinks will discolor the stone. But prompt wiping of fresh spills prevents any staining. Dried-on coffee and wine stains still have a good chance of being removed with the right poultice or cleaning solution.
Does Lemon Juice Stain Quartz?
Yes, lemon juice and other acids can stain quartz countertops. Citrus fruit juices contain citric acid, which can etch into the surface over time. Cutting large amounts of lemons directly on quartz will cause damage. However, briefly wiping up drips of lemon juice will not stain if cleaned up right away.
Can Oil Stains Be Removed from Quartz?
Yes, oil stains can be removed from quartz using a poultice, degreasing cleaner, or solvent. Vegetable oil, grease splatter, and other food oils will stain quartz dark brown if left overnight. But prompt use of absorptive powders mixed with soap and water can extract fresh oil stains. For dried oils over 24 hours old, stronger solvents may be needed.
Do Permanent Markers Stain Quartz?
Permanent markers contain pigmented dyes that penetrate surfaces. These stains are challenging to remove from quartz. The best approach is using solvents like acetone or alcohol to break down the dyes. Severe marker stains may require resurfacing if the color has soaked in deeply. Avoid using permanent markers directly on any quartz installation.
How Do You Remove Rust Stains from Quartz?
For light surface rust stains, use oxalic acid powder mixed into a poultice and apply to the stain. Lemon juice also helps dissolve rust marks. For heavier rust discoloration in the surface, try a rust/iron remover product specifically formulated for stone. Professional help may be needed for rust that penetrates into etch marks or cracks. Prevent these stains by keeping steel pads, tools, and cast iron cookware away from quartz surfaces.
Although quartz countertops can become stained, these incidents are relatively rare compared to other surfaces. By understanding what causes stains and utilizing the right cleaning methods, most stains can be avoided or removed before they become permanent. With some care and prompt attention, it is possible to keep quartz looking pristine for years.
Following preventative habits, addressing stains quickly, and periodically re-sealing and polishing are the keys to stain-free quartz. While no stone is completely stain-proof under all circumstances, quartz comes remarkably close when properly maintained. Use this guide to keep your quartz counters in immaculate shape.
