Quartz countertops have become an increasingly popular option for kitchen and bathroom remodeling projects in recent years. Often touted as a lower maintenance and more durable alternative to natural stone countertops like granite and marble, quartz counters are made from ground quartz particles combined with resins and pigments.
One of the most common questions homeowners have when considering quartz countertops is: are quartz countertops stain resistant? The short answer is yes, quartz counters are highly stain-resistant and unlikely to stain under normal use. However, they are not completely stain-proof. With proper care and maintenance, quartz countertops can retain their beautiful, pristine appearance for many years.
How Stain Resistant Are Quartz Countertops?
Quartz counters are engineered composites made from approximately 90% ground natural quartz minerals combined with polymer resins that bind the material together. The resins make the countertop non-porous, making it resistant to stains caused by spills and liquids.
Unlike porous natural stones, quartz does not need to be sealed regularly to prevent stains. Liquids and oils do not easily penetrate the surface, allowing spills to be wiped away without leaving marks.
However, while quartz has excellent stain resistance, it is not impervious. Highly pigmented liquids like wine, coffee and fruit juices can stain quartz if left to sit for prolonged periods. Oils, greases and other liquids can also stain if allowed to pool on the surface.
With prompt cleanup of spills, quartz countertops are highly unlikely to stain under normal household use. Their non-porous quality makes them one of the most stain-resistant countertop materials on the market today.
What Types of Stains Can Damage Quartz?
While quartz counters have excellent stain resistance, they are still vulnerable to some types of stubborn stains if proper care is not taken. Here are some of the most common stains quartz is prone to:
Wine and Juice
Pigmented liquids like red wine, grape juice, cranberry juice and tomato sauce are some of the biggest staining threats for quartz counters. If spills are allowed to sit for an extended time, the pigments can seep into the microscopic pores in the material and cause stubborn, reddish stains.
However, if wiped up promptly, these types of spills will not stain quartz. The key is quick cleanup within 5-10 minutes of the spill occurring. Allowing juices and wines to puddle for an hour or more almost guarantees a stain.
Oil and Grease
Cooking oils and greases left on the counter can also stain quartz surfaces. If oil is allowed to pool and sit for prolonged periods, it can penetrate the material and create dark, greasy stains. Wiping up spills immediately is key to prevent oil stain damage.
Dyes and Pigments
Direct contact with strongly colored dyes or pigments can also cause stubborn staining. Spilling a concentrated dye, makeup, or food coloring and failing to wipe it up quickly can allow the pigment to soak into the quartz. Minimizing contact time is crucial with pigmented spills.
Heat
Excessive heat can also damage quartz and cause discoloration. Placing hot pans, pots or baking sheets directly on the counter instead of a trivet can potentially burn the surface and create whitish marks. While quartz is heat resistant, using trivets and hot pads is recommended to prevent thermal damage.
How to Remove Stains from Quartz Countertops
If stains do occur on your quartz counters, prompt removal is recommended to prevent permanent damage. Here are some DIY methods to remove common quartz stains:
Clean with Mild Soap and Water
For minor stains, start by cleaning the affected area with a few drops of mild dish soap and warm water. Use a soft cloth or sponge in gentle, circular motions. Rinse thoroughly. Often this simple cleaning is sufficient to remove fresh stains.
Baking Soda Paste
For more stubborn stains, make a paste with baking soda and water. Apply to the stain and let sit for 5-10 minutes before scrubbing and rinsing. Baking soda is a gentle abrasive that can lift many types of stains without damaging the quartz surface.
Hydrogen Peroxide
An effective bleaching agent, hydrogen peroxide can help remove pigmented stains like wine, coffee and fruit juice. Apply full-strength hydrogen peroxide and let bubble for 2-5 minutes before wiping away. Rinse surface thoroughly.
Barkeeper’s Friend
This powdered cleanser contains oxalic acid designed to remove rust, mineral deposits and stubborn stains. Make a paste with water, apply to the stain and let sit briefly before scrubbing and rinsing. Use caution, as abrasives may dull quartz’s polish over time.
Acetone
For extreme stains, use a small amount of acetone on a clean cloth to spot treat the stain. Avoid excessive rubbing and immediately rinse surface with water. Only use acetone as a last resort, as it can dull quartz finishes.
Preventing Stains on Quartz Countertops
An ounce of prevention is worth a pound of cure when it comes to caring for quartz counters. By taking a few preventative steps, you can keep your quartz surfaces looking pristine:
- Wipe up all spills immediately, especially wine, oil and pigmented liquids
- Avoid excessive direct heat from hot pans and baking sheets
- Use trivets, hot pads and cutting boards to protect surface
- Clean quartz regularly with a mild, non-abrasive cleaner
- Avoid harsh chemicals and acidic cleaners that can etch surface
- Reseal quartz annually with a specialty countertop sealer
- Don’t use quartz as a cutting board to avoid nicks and cuts
By taking quick action when spills occur and handling quartz gently during routine use, you can enjoy stain-free, like-new counters for many years.

How Quartz Countertops Are Made
To understand quartz’s durability and stain resistance, it helps to know a bit about the manufacturing process. Quartz counters are made by combining ground quartz mineral particles with polymer resins under intense heat and pressure.
Raw Materials
About 90% of a quartz slab is composed of natural quartz aggregates. Quartz is an abundant hard mineral found in granite, sandstone and other natural stones. Quartz particles are extremely hard and resilient.
Polymeric resins make up about 10% of the material. Resins act as a binder to adhere the quartz particles together into a solid slab. Pigments added to resins provide the color and pattern.
Mixing Process
Quartz aggregates, polymers and pigments are combined in precise proportions and mixed together. The exact formula varies between quartz brands and colors.
Vibrocompression
The blended quartz material is poured into molds and compressed under enormous pressure. The combination of heat, pressure and vibration compacts the quartz slabs extremely densely.
Curing/Hardening
After initial shaping, the quartz slabs are moved to curing ovens. Intense heat hardens the resins to their permanent solid form. Temperatures often exceed 300°F during this curing stage.
Finishing
Once cooled and set, the finished slabs are polished to a smooth, shiny finish. Some brands use extra vibrocompression after curing to densify the material further. The slabs are then ready for shipping to distributors.
