Do Quartz Countertops Stain Easily?

Quartz countertops are an increasingly popular option for kitchen and bathroom surfaces due to their durability, style, and low maintenance. However, many homeowners wonder – do quartz countertops stain easily? The short answer is no. When properly sealed and cared for, quartz countertops are highly resistant to stains. Here’s a more in-depth look at the stain resistance of quartz.

What Makes Quartz Resistant to Stains?

Quartz countertops are engineered from about 90% ground quartz crystals combined with polymer resins and pigments. The quartz grains make the material very dense and non-porous, making it difficult for stains to penetrate the surface. Additionally, the resin forms a protective barrier that repels moisture.

Here are some of the key properties that prevent quartz from staining:


Unlike natural stone and tiles, quartz has an extremely low porosity of less than 0.5%. This means liquids and grime have a very hard time seeping into the material.

Stain-Resistant Resins

The polymer resins used in the fabrication of quartz have innate stain resistance. These help prevent absorption of oils, juices, wine, and other liquids that can leave permanent discoloration.

High Density

With about 90% ground quartz in the material, quartz countertops are very dense and compact. This leaves little room for stains to penetrate the surface.

Factory Applied Sealant

Reputable quartz manufacturers apply a durable sealant to countertops during fabrication. This provides an added layer of protection against moisture absorption.

How to Keep Quartz Stain-Free

While quartz is highly stain-resistant, it still requires some periodic maintenance to look its best. Here are some tips for keeping quartz spotless:

Clean Spills Quickly

Don’t let spills sit on the countertop. Immediately wipe up oils, wine, coffee, juice or other liquids. This prevents staining agents from dwelling on the surface.

Daily Cleaning

Use a mild soap and warm water to clean quartz daily. This removes dust, grease and debris that can lead to staining over time.

Re-seal Every 1-2 Years

Though quartz comes pre-sealed, it helps to have it re-sealed every couple of years by a pro. This reinforces the protective barrier.

Avoid Harsh Chemicals

Don’t use abrasive cleaners or bleach on quartz counters. Always check cleaner labels for compatibility with engineered stone.

Use Cutting Boards

Use cutting boards when chopping, slicing or prepping food. This protects the quartz from knicks and scratches that could allow stains.

What If a Stain Occurs?

While rare, stains on quartz can happen, especially when spill cleanup is delayed. Here are some remedies:

  • For oil-based stains, use an alkaline cleaner made specifically for quartz. This usually removes stains without damaging the surface.
  • For stubborn stains, make a paste of baking soda and hydrogen peroxide. Apply to the stain and let sit for an hour before scrubbing and rinsing.
  • For permanent stains that etching the surface, you may need to call in a pro to sand and re-polish the quartz.

The Bottom Line

Quartz countertops offer superior stain resistance compared to most other countertop materials. With simple precautions like prompt cleanup and periodic re-sealing, quartz counters will stay beautiful and stain-free for many years. Be sure to follow manufacturer care guidelines to get the most out of your investment. With a little maintenance, quartz countertops do not stain easily.

Frequently Asked Questions About Quartz Stain Resistance

Does Quartz Stain Easily Compared to Other Countertops?

No. Quartz is far more stain resistant than surfaces like marble, granite, laminate, wood and tile. The non-porous quality makes it highly impervious to stains. It also resists scratches better than most options.

What Should You Not Put on Quartz?

Avoid exposing quartz counters to strong chemicals like paint remover, furniture strippers, oil soaps, drain cleaners, etc. These can damage the protective resin layer. Also keep nail polish, perfumes and solvents off the surface.

Does Quartz Stain from Mustard? Ketchup? Wine?

Quartz resists stains from all common food and drinks, including mustard, ketchup, wine, coffee, juices, oils, etc. However, spills should be wiped up quickly to prevent any chance of permanent staining.

Can You Remove Stains from Quartz Countertops?

Yes, stains can usually be removed from quartz using alkaline quartz cleaners or baking soda pastes. For tough stains, the surface may need to be professionally sanded and re-polished. Avoid using bleach or abrasives.

How Do You Clean Oil Stains from Quartz?

Use a mild detergent and warm water first. If needed, apply an alkaline-based cleaner made specifically for quartz. Rub gently, rinse thoroughly and dry. Do not use abrasive pads or powders that could scratch the surface.

Does Sealing Prevent Quartz Stains?

Sealing provides an added layer of protection by preventing moisture from penetrating the surface. However, quartz does not require regular sealing like some natural stone surfaces. Factory applied sealants last many years.

Should White Quartz Countertops be Sealed?

Sealing is always a good idea for white quartz counters which can show staining and marks more easily. Reapply sealant every 1-2 years per manufacturer guidelines to reinforce moisture protection.

How Long Does a Quartz Countertop Sealer Last?

Factory applied sealants are designed to last many years. For residential settings, adding a fresh seal coat every 1-2 years is recommended for optimal stain protection. Commercial settings may need more frequent resealing.

What Household Items Can Stain Quartz?

Prolonged exposure to oils, dyes, solvents or acids can potentially stain quartz. Examples include vegetable oil, ink, nail polish, paints, bleach, wine, citrus juices, etc. Wipe up quickly to avoid any issues.


Quartz countertops offer unparalleled stain resistance compared to other popular options like granite, marble and laminate. With a highly non-porous surface and protective resin barrier, quartz prevents most common kitchen and bathroom stains beautifully when properly cared for. By promptly cleaning up spills, avoiding harsh chemicals and periodically resealing, quartz counters will stay pristine and stain-free for many years. For homeowners seeking surfaces that combine good looks with durability and easy maintenance, quartz is hard to beat. With just a little routine care, quartz countertops do not stain easily.
