Do Quartz Countertops Get Stained?

Quartz countertops are popular options for kitchen and bathroom remodels because of their durability, appearance, and low maintenance. However, many homeowners wonder – do quartz countertops get stained? Understanding what can stain quartz counters is key to keeping them looking pristine.

What is Quartz?

Quartz countertops, sometimes called engineered stone, are made from ground quartz crystals combined with resins and pigments. The crystals make up approximately 90% of the material while the resins act as a binder.

Compared to natural stone like granite and marble, quartz offers superior resistance to stains, scratches, and heat. The resins create a sealant effect that makes quartz less porous than natural stone. However, quartz is still susceptible to some staining.

Do Quartz Countertops Get Stained?

While quartz resists stains better than most surfaces, staining is still possible under certain circumstances. Here are some factors that impact how easily quartz can become stained:


Quartz has very low porosity thanks to the resin used in the manufacturing process. This makes it more stain-resistant than porous natural stone. However, small pores still allow some liquids to seep in and potentially cause stains.

Surface Texture

The texture of the quartz can impact stain resistance. Smoother quartz with a polished finish provides less surface area for liquids to seep into. Quartz with more pronounced particulate and a rougher texture is more prone to trapping stains within its crevices.

Color and Pattern

Solid quartz colors like white and gray hide stains better than quartz with bold patterns or speckles. Busy quartz patterns can make stains harder to notice, while light quartz shows all discoloration clearly.

Quality of Manufacturing

Higher quality quartz brands engineer their products to be maximally non-porous and resistant to staining. Lower priced quartz or quartz made with inferior manufacturing can be more susceptible to stains.

Maintenance and Cleaning

Regular cleaning and prompt treatment of spills prevents staining. Quartz that is poorly cared for and cleaned is much more likely to accumulate hard-to-remove stains over time.

With these factors in mind, quartz can become stained under the right circumstances. However, the staining is often mild and can be removed with the proper cleaning methods.

What Can Stain Quartz Countertops?

While quartz resists many common kitchen and bathroom stains, it is not completely impervious. Here are some substances that can potentially stain quartz:

Oils and Grease

Food oils, cooking grease, and other greasy substances can seep into quartz and leave behind discoloration if left for prolonged time periods. Oils from foods like olive oil, vegetable oils, and butter create oily stains.

Red Wine

The pigments in red wine can leave faint stains on quartz surfaces. White wine and other clear alcohols generally do not stain.

Tomatoes and Tomato Sauce

The acids and pigments in tomatoes and tomato sauce can stain quartz after prolonged exposure. Marinara sauce, ketchup, pizza sauce, or tomato juice left overnight often stain.

Coffee and Tea

Like red wine, the pigments in dark teas, coffee, and coffee grounds can sometimes stain quartz. Coffee and tea stains are generally mild but can build up over time.

Fruit Juices

Acidic fruit juices like lemon, lime, grapefruit, or orange juice can all potentially etch or stain quartz. Citric acid and color pigments are problematic.

Spices and Condiments

Staining can occur from spices like turmeric, paprika, cinnamon, curry powder, and saffron. Mustard, salsa, soy sauce, and other strongly pigmented condiments may also stain.

Harsh Chemicals and Cleaners

Applying harsh chemicals like paint removers, oven cleaners, drain cleaners, bleach, and alkaline cleaners can damage quartz and make it more stain-prone.

With care and prompt cleaning, most household stains can be prevented or removed from quartz. But it’s important to be aware of what can potentially mark the surface.

Do Stains Soak Into Quartz Countertops?

While stains are possible with quartz, they rarely soak deep into the material. The resin binder forms a protective seal that prevents most spills from fully penetrating the quartz surface.

However, some staining agents can seep into microscopic pores and cause discoloration:

  • Oils and Grease: Food oils may slowly sink into pores due to long contact. Regular cleaning prevents deep oil absorption.
  • Pigmented Liquids: Substances like red wine, coffee, and fruit juices discolor the tiny pits they enter over time.
  • Strong Chemicals: Chemical spills partially break down the resin seal and open more tiny crevices to be stained.
  • Etching Liquids: Acidic substances like vinegar, lemon juice, and tomato products etch the surface and make it more stain-prone.

With most stains only affecting the superficial layer, quartz retains its overall appearance and integrity. But it’s still vital to wipe up spills quickly to limit absorption.

How to Remove Stains from Quartz Countertops

While stains are an annoyance, they can often be removed from quartz surfaces. Here are some stain removal techniques:

Gentle Cleaners

For mild stains, a gentle cleaner like soapy water, glass cleaner, or vinegar works well. Spray the stain and let sit briefly before wiping clean. Avoid abrasive cleansers.

Baking Soda and Hydrogen Peroxide

For tougher stains, make a paste of baking soda and hydrogen peroxide. Apply to the stain, allow to bubble for 5-10 minutes, then wipe clean. Rinse thoroughly.

Bleach-Based Cleaners

Premium quartz-specific cleaners like CLR and Bartender’s Friend contain bleach to break down stains. Use according to package directions. Avoid bleach on lower-grade quartz.

Magic Eraser

Magic erasers work well on superficial stains from oils, juices, coffee, tea, etc. Gently rub in a circular motion until the stain fades. Avoid excessive scrubbing.


For stubborn stains, apply a small amount of acetone to a clean cloth and rub gently on the stain. Repeat if needed, but avoid overusing acetone.

Restoration Kit

Commercial quartz restoration kits contain specialized abrasives and cleaners tailored to remove stains without damaging the surface. They effectively deep clean the quartz.

With persistence, the right cleaning approach can remove most quartz countertop stains. But prevention through rapid spill wipe-up is key.

Do Quartz Countertops Stain Over Time?

When properly cared for, quartz resists permanent staining and retains its like-new appearance for many years. However, neglecting maintenance may allow stains to accumulate slowly.

Here are some ways quartz can pick up stains over time:

  • Allowing spills to sit for prolonged periods before cleaning
  • Using harsh, abrasive cleaners that damage the protective resin layer
  • Failing to clean up oil drips and grease buildup from cooking
  • Not cleaning coffee, wine, juice, and other pigmented liquids promptly
  • Allowing soap, minerals, and hard water deposits to build up

With daily use, the small pores and micro-scratches in quartz provide opportunities for gradual staining if care is inadequate. But consistent maintenance prevents long-term stain issues.

Does Sealing Prevent Quartz Stains?

Sealing is often recommended for natural stone countertops like granite and marble to reduce staining. But quartz countertops do not require sealing thanks to their non-porous resin layer.

In fact, sealing quartz provides no stain protection benefit. Sealing products cannot penetrate beyond the built-in resin barrier. Some quartz companies even warn that sealants could discolor or damage the engineered stone surface.

Maintaining quartz with mild soap and water keeps it stain-free. Relying on sealants provides a false sense of security against stains. Simply wiping spills quickly and avoiding harsh cleaners is the best approach.

Are There Permanent Stains on Quartz?

Most stains on properly cared for quartz countertops are mild and removable. But some circumstances can lead to permanent, irreversible staining:

  • Prolonged Exposure to Staining Agents: Letting stains sit for very lengthy times allows deep absorption into pores. Adhesives, oils, and pigments may leave lasting marks.
  • Burn Marks: Hot pots and pans sitting directly on quartz can scorch the surface and leave permanent darkened burn marks.
  • Structural Damage: Cuts, gouges, chips, and cracks breach the resin layer and expose porous quartz interior. Staining is inevitable.
  • Failed DIY Installation: Improper seam joining, inadequate support, and poor caulking can all cause permanent stains. Leave it to the pros.
  • Harsh Chemical Damage: Bleach, paint strippers, oven cleaners, etc. degrade quartz’s resin protection leading to permanent staining.

With proper installation, care, and maintenance, permanent stains are unlikely. But mishandling and neglecting quartz can lead to irreparable discoloration issues.

How to Prevent Stains on Quartz Countertops

Preventing stains on quartz countertops is much easier than trying to remove them after the fact. Here are some stain prevention best practices:

  • Wipe up all spills promptly, especially oils, pigmented liquids, and acidic substances.
  • Always use cutting boards for food prep. Never cut directly on the quartz.
  • Clean quartz regularly with a gentle soap and water solution.
  • Avoid exposing quartz to harsh chemicals like bleach, alkaline cleaners, etc.
  • Place hot pans on trivets or pads. Never directly on the quartz surface.
  • Don’t let soap scum, hard water marks, and mineral deposits build up.
  • Consider using a grout release agent on quartz tiles to repel stains.
  • Re-seal quartz around sinks and backsplashes annually if needed.

With attentive care and maintenance, quartz countertops remain pristine and resistant to stains. But neglecting basic precautions can compromise their stain resistance.

Is Staining a Sign of Low Quality Quartz?

Moderate staining does not necessarily indicate low-grade quartz. Even premium quartz brands can experience some staining if not properly maintained.

However, excessive staining and permanent discoloration are often signs of inferior quartz:

  • Higher Porosity: Lower quality manufacturing creates a more porous quartz vulnerable to deep staining.
  • Weaker Resins: Less expensive resins result in diminished stain protection compared to top brands.
  • Thinner Layer: Budget quartz tends to have a thinner layer of resin coating over the stone particles.
  • Prone to Damage: Cheap quartz chips, scratches, and cuts more easily, exposing the interior to stains.
  • Lower Stain Resistance Standards: Budget brands do not engineer their quartz for maximum stain resistance.

While no quartz is 100% stain-proof, high-end materials, rigorous engineering, and quality manufacturing minimize staining issues.

Does Quartz Yellow Over Time?

Quartz countertops maintain their bright, vibrant color for many years and do not naturally yellow or fade with age. However, long-term staining can cause some faint discoloration.

Gradual yellowing of a quartz surface indicates staining problems:

  • Oils from cooking seeping into microscopic pores
  • Pigmented liquids like wine and juice absorbing over many years
  • Soap scum, hard water marks, and mineral buildup
  • Harsh cleaners degrading the protective resin layer

This yellowing occurs slowly but can dull the appearance of white, light, and vibrant quartz colors. Proper cleaning and prompt spill handling prevent yellow discoloration.

Is Staining Covered by the Quartz Warranty?

Many quartz companies offer 10-15 year warranties. However, these warranties exclude normal wear-and-tear staining. Warranties only cover manufacturing defects.

Quartz owners are responsible for maintaining the countertops to prevent stains. Allowing preventable spills and stains to accumulate falls under standard ownership maintenance rather than a warranty issue.

However, some warranties may provide limited coverage for truly permanent stains that cannot be removed despite correct care. But in most cases, the owner must prevent stains.
