Quartz countertops are an increasingly popular option for kitchen and bathroom remodeling projects. Made from crushed quartz blended with resins and pigments, quartz counters are valued for their durability, low maintenance, and stylish appearance. However, many homeowners wonder: can quartz countertops stain?
What is Quartz?
Quartz is a mineral found abundantly in nature. It is composed of silicon and oxygen atoms bonded together in a crystalline structure. Natural quartz is very hard and resistant to both chemicals and heat.
For countertops, quartz crystals are ground into a fine powder and then blended with polyester resins and pigments. This engineered stone material is molded into slabs and polished into the finished product installed in homes. The resins bind the quartz particles together into a cohesive material.
The Stain Resistance of Quartz
One of the biggest benefits of quartz counters is their excellent stain resistance. The resin coating creates an impervious surface that prevents stains from penetrating into the material.
Quartz has a non-porous quality unlike natural stone materials such as granite, which can absorb liquids if not properly sealed. The resins make quartz repel water, oil, juice, wine, and many other potential staining substances.
However, while quartz has superior stain resistance, it is not completely stain proof. With the right substances and circumstances, quartz can stain.
What Can Stain Quartz Countertops?
While quartz counters resist most everyday spills and messes, some substances can leave permanent discolorations if not cleaned up promptly. Here are some of the offenders that can stain quartz:
Oils like canola, vegetable, and olive oil can sink into quartz pores over time and leave oil stains. Grease and cooking oils are likely to leave residue. The same goes for nut and seed oils from foods like tahini or peanut butter.
Cosmetics and beauty products containing oil, like certain cleansers and moisturizers, may also stain.
Dark-hued liquids like wine, fruit juice, tea, vinegar, and tomato sauce can stain quartz. Dyes and pigments in these items can leave stubborn marks. Coffee and other drinks containing caffeine are also staining culprits.
Indelible markers and pens can leave inky stains on quartz. Felt tip, Sharpie, and ballpoint pens contain pigments that can bond with the surface. These stubborn stains require aggressive cleaning to remove.
Industrial-strength cleaners and chemicals containing acids, alkalis, or solvents can damage and discolor quartz. Avoid exposing quartz counters to paint removers, oven cleaners, drain openers, and toilet bowl cleaners.
Excessive heat from hot pots and pans can scorch quartz and cause permanent burns or cracks. Always use trivets and hot pads to protect quartz surfaces.
How to Clean and Remove Stains from Quartz
While quartz can stain, it’s also very resilient against damage. With prompt cleaning using the proper methods, you can often remove stains from quartz completely. Here are some tips:
Blot Stains Quickly
If you spill something like wine or coffee on your quartz, immediate action is required. Blot up the spill right away with an absorbent cloth. Avoid abrasive scrubbing, which can drive the stain deeper.
Flush with Water
For liquid spills, rinse the area with warm water to dilute and flush away staining residues. Use a soft sponge or damp microfiber cloth to gently wipe.
Use Mild Cleaners
Clean quartz with a gentle liquid dish soap diluted in warm water. For tougher stains, use a specialized stone cleaner made for engineered quartz. Avoid harsh chemicals or abrasive powders.
Baking Soda Paste
For oil-based stains, make a paste with baking soda and water. Apply to the stain and let sit for several hours before scrubbing and rinsing clean. Baking soda helps lift deep oil stains.
As a bleaching agent, hydrogen peroxide can lift pigmented stains. Use a 3% solution, apply lightly with a soft cloth, let sit for 10 minutes, and rinse clean. Be careful, as prolonged exposure can degrade quartz polymers.
Mr. Clean Magic Eraser
These popular melamine foam blocks can effectively scrub away pigmented stains and discoloration. Be gentle, as the abrasive pads can dull quartz if rubbed too aggressively.
For stubborn stains engrained into the quartz, use a blow dryer to gently heat the surface while cleaning. This can help loosen staining residues from the pores. Avoid burning or cracking the quartz.
How to Prevent Stains on Quartz
Preventing stains on quartz requires simple daily habits. Follow these tips to keep your quartz counters pristine:
- Wipe up spills immediately, don’t let them sit
- Always use cutting boards, never cut directly on quartz
- Clean counters frequently with a mild soap and water
- Avoid harsh chemicals that can damage the surface
- Use hot pads and trivets for hot pots and pans
- Seal any cracks and crevices with caulk to prevent moisture intrusion
- Reapply sealers every year as added protection
With regular cleaning and observation of a few precautions, quartz countertops will maintain their good looks and avoid unsightly staining. Be vigilant, as a little care goes a long way in preserving quartz surfaces.
Frequently Asked Questions About Stains on Quartz Countertops
Can you get oil stains out of quartz?
Yes, oil stains can generally be removed from quartz using baking soda and water paste and a soft cloth. For tough stains, use a gentle cleaner like Soft Scrub or BonAmi. Avoid harsh chemicals that can damage the resin binders.
How do you get permanent marker off quartz?
Rubbing alcohol or hand sanitizer can help lift permanent marker stains from quartz. Apply a small amount and gently scrub with a non-abrasive pad. Be patient, going slowly to avoid spreading the stain. Repeated light applications may be needed for stubborn stains.
Does quartz stain like granite?
No. Because it is engineered with polymers, quartz is less porous than natural stone like granite. Quartz resists stains far better than granite, which requires vigilant sealing. However, no surface is 100% stain proof, so spills on quartz should still be cleaned up quickly.
Can you bleach quartz countertops?
It is not recommended. While diluted bleach can disinfect quartz, prolonged exposure can damage the resin binders and fade pigments. For deep cleaning, use a mild detergent, vinegar, hydrogen peroxide, or ammonia instead of harsh bleach.
Will lemon juice stain quartz?
Yes, prolonged contact with acidic juices like lemon, lime, orange, or tomato can etch and stain quartz. Quartz is durable but still vulnerable to acidic etching over time. Wipe up spills immediately and avoid using quartz as a cutting board.
Does Windex stain quartz?
No, Windex is generally safe for cleaning quartz. However, avoid the vinegar-containing Windex Multi-Surface formula, as vinegar is acidic. Use regular Windex applied lightly with a soft cloth. Never allow harsh cleaners to soak quartz surfaces for extended periods.
Can you stain quartz intentionally?
It is challenging to stain quartz intentionally. Because it is non-porous, stains have a hard time penetrating the surface. However, prolonged exposure to very dark liquids could cause discoloration over time. This would likely void the manufacturer’s warranty.
Is Quartz Prone to Staining?
Quartz has excellent resistance against most household stains. However, no surface is completely immune. Quartz can stain when subjected to oils, pigments, harsh chemicals, and heat. With vigilant daily care and cleaning, stains can be prevented or removed to maintain the original beauty of quartz.
Compare quartz to other countertop materials:
- Granite: More prone to staining than quartz since it is porous. Needs regular sealing.
- Marble: Very prone to staining and etching without diligent sealing.
- Laminate: Resists stains well but can scratch and scorch easily.
- Wood: Susceptible to stains, scratches, and water damage without careful maintenance.
- Concrete: Can stain without a sealed finish and also needs resealing over time.
Quartz offers excellent stain resistance compared to natural stone and many other commonly used countertop materials. With sensible precautions, quartz countertops will stay looking like new for many years.
