Quartz countertops are an increasingly popular option for kitchen and bathroom remodeling projects. Made from ground quartz crystals blended with resins and pigments, quartz offers an attractive, low-maintenance, and durable surface. However, many homeowners have questions about how resistant quartz really is to stains and scratches. Here is an in-depth look at whether quartz countertops stain or scratch.
What is Quartz?
Quartz is one of the hardest minerals found in nature, ranking just under diamonds in hardness. Natural quartz crystals are ground down into a fine powder to produce the engineered stone used to create quartz slabs and countertops.
The quartz powder comprises about 90-95% of a quartz countertop. It is combined with pigments for color and polyresin for binding. The result is a non-porous surface that is highly resistant to stains, scratches, heat, and cracks.
Compared to natural stone like granite and marble, quartz offers superior durability and stain resistance. And unlike laminate, quartz does not peel or warp. This makes it an ideal countertop material for busy kitchens and bathrooms.
Do Quartz Countertops Stain?
One of the biggest advantages of quartz over natural stone is that it does not easily stain. The non-porous surface prevents liquids and foods from penetrating into the countertop. Instead, most spills and messes remain on the surface and can be easily wiped away.
However, while quartz resists stains, it is not 100% stain proof. Extremely pigmented liquids like red wine, coffee, and tomato sauce can leave light stains if left to sit for prolonged periods. But these stains tend to fade over time and are not permanent.
Here are some tips to prevent stains on quartz:
- Clean up spills immediately, don’t let them sit for extended periods
- Avoid exposing the countertops to strong chemicals and cleaners
- Use a gentle non-abrasive cleaner and soft cloth for regular maintenance
- Re-seal the countertops every 1-2 years for added protection
With proper care and cleaning, quartz countertops will retain their beautiful, like-new appearance for many years without taking on stains. Prompt cleanup of spills is key to keeping quartz looking pristine.
Do Quartz Countertops Scratch?
Along with stain resistance, quartz also has excellent scratch resistance due to the hardness of the quartz aggregates within it. It stands up very well to knives, utensils, pots/pans, and other daily kitchen wear and tear.
However, quartz can be scratched by extremely sharp objects or excessive pressure. Things that should be avoided include:
- Cutting directly on the countertop surface
- Dragging heavy or hard objects across the surface
- Applying too much pressure with knives or utensils
Scratches on quartz are typically surface level only. They do not penetrate deep into the material. Light scratches can often be buffed out through professional polishing. But it is still best to take care and avoid exposing quartz to scratch-prone situations.
Using cutting boards and not dragging appliances/cookware across the countertops will help prevent scratches. Quartz holds up remarkably well to normal daily use, but extreme impacts or abrasions can leave marks.
How Does Quartz Compare to Other Countertop Materials for Stains and Scratches?
- Granite – More prone to staining and etching than quartz. Needs regular sealing to prevent stains from soaking in. Can scratch under heavy impact.
- Marble – Very porous and easily stained without diligent sealing/polishing. Etches from acidic liquids. Scratches more easily than granite.
- Laminate – Prone to chipping, peeling, scratches, burns, and stains with unprotected seams. Durability does not compare to stone.
- Stainless Steel – Very stain resistant and does not require sealing. Can scratch and dent fairly easily from impact or sharp objects.
- Butcher Block – Easily stained and scratched unless properly sealed and cared for. Requires frequent oiling/waxing to maintain appearance.
- Concrete – Porous and needs consistent sealing to resist stains/damage. Can etch and scratch without proper maintenance.
- Soapstone – Stains require sanding/resealing to remove. Repeated treatments needed to maintain look. Scratches under pressure.
Quartz provides an optimal balance of stain, scratch, and heat resistance compared to alternatives. It performs better than most natural stone and engineered products, offering durable low-maintenance functionality.
How to Remove Stains from Quartz Countertops
While quartz resists stains well, they can occasionally occur from highly pigmented spills. Here are some steps to remove stains from quartz:
For dried/set stains:
- Mix baking soda and water into a paste and spread over stain
- Let paste sit for 5 minutes to lift stain
- Scrub with soft cloth or sponge and rinse clean
- For stubborn stains, use undiluted white vinegar and scrub
- Rinse thoroughly and dry area completely
For fresh stains:
- Blot liquid spill immediately
- Clean area with non-abrasive quartz cleaner and soft cloth
- Rinse with water and dry completely
- Avoid using cleaners that can discolor quartz
Tips:
- Test stain removers on small inconspicuous area first
- Never use abrasive pads, scouring powders, or bleach products
- Minimize pressure to avoid damaging the surface
- Repeat treatments if stain persists
- Consult a pro for difficult stains or etching
With the right techniques and products, most stains can be removed from quartz countertops without damaging the surface. But professional help may be needed for stubborn stains that do not respond to DIY treatments.
How to Repair Scratches on Quartz Countertops
Minor scratches on quartz can often be buffed out carefully at home. For deeper scratches, professional repair or refinishing may be required. Here are some options for fixing scratches:
Minor/Surface Scratches:
- Use a plastic putty knife to apply a thin layer of clear nail polish over the scratch
- Let dry completely and repeat until buildup is slightly above surface
- Buff excess gently with extra fine (1500-2000) grit sandpaper
- Clean area well and finish by polishing with a quartz polish product
Deeper Scratches:
- Purchase a quartz repair kit with colored fillers to match your countertop
- Fill in scratch according to kit directions, smooth, and let dry
- Buff excess filler gently and clean area afterwards
- May take multiple applications for best results
Severe Scratches:
- Consult a professional stone restoration company
- Technicians have tools to grind down scratches and resurface the quartz
- Refinishing restores the smooth finish and removes deeper marks
- Cost depends on size of damaged area and repair required
Tips:
- Take care not to further damage the surface when doing repairs
- Test products/methods on scraps or inconspicuous spots first
- Hairline cracks can often be filled vs. needing full refinishing
- Protect repairs by adding a sealant afterwards DIY repairs work well for minor scratch touch-ups on quartz. But extensive damage may call for a trained stone pro to re-polish and resurface the countertops.
Do Quartz Countertops Need to Be Sealed?
Unlike natural stone, quartz does not require regular sealing. The resins and polymers used in the fabrication of quartz make it non-porous and prevent the need for sealing. Liquids and oils do not penetrate the surface, so sealing is not essential.
However, some homeowners choose to occasionally apply a sealant to their quartz countertops for added protection:
Reasons to Seal Quartz:
- Provides extra barrier against very stubborn stains
- Can make cleaning/maintenance easier
- Helps prevent etching from exposure to acids
- Fills in hairline scratches and improves luster
- Prolongs the like-new appearance and shine
How Often to Seal Quartz:
- Countertops are pre-sealed during manufacturing
- Reapply sealant every 1-2 years for optimal results
- New installations may need sealing sooner than factory seals
- Use only sealants made specifically for quartz
Tips for Sealing:
- Clean the countertops thoroughly before applying sealant
- Use a soft lint-free cloth to apply sealant evenly
- Let the sealant soak in fully before using the countertops
- Avoid water or cleaning for 24 hours after sealing
- Always test in a small area first and follow product directions
Sealing is not required for quartz but can provide added protection with minimal effort. Use quartz-specific sealers and limit sealing to once every year or two for best results.
How to Clean Quartz Countertops
Routine cleaning is important for keeping quartz looking like new. Follow these best practices:
- For daily cleaning, use a mild soap and warm water
- Avoid abrasive cleaners or scrubbing pads that can damage the surface
- For food prep areas, disinfect with a diluted bleach cleaner occasionally
- Rinse with clean water and dry with a soft cloth after cleaning
- Immediately wipe up spills, oils, and residue from cooking/drinks
- Use a squeegee to dry sinks or backsplashes after use
- For hard water spots, use a 50/50 vinegar and water solution to wipe clean
- Polish periodically with a quartz-specific polish to reinforce shine
What Not to Use:
- No acidic or alkaline cleaners like lime/rust removers
- Avoid stain removers with dyes that can discolor the surface
- No grease removers or mineral spirits that can break down sealants
- Nothing abrasive like scouring powder, pads, or scrub brushes
Tips:
- Inspect countertops under light routinely to spot issues early
- Deep clean with dilute hydrogen peroxide for stubborn messes
- Never use counters as cutting boards or workbenches
With regular gentle cleaning and prompt spill removal, quartz countertops will retain their pristine, like-new sheen for many years. Avoid harsh chemicals and abrasives that can damage the protective finish.
