Quartz countertops are one of the most popular options for kitchen and bathroom surfaces today. Made from ground quartz crystals combined with resins and pigments, quartz offers an attractive, low-maintenance, and durable alternative to natural stone and laminate. However, even high-quality quartz surfaces can lose their shine over time without proper care. Here’s how to keep quartz looking its best for years to come.
Clean Regularly and Use the Right Products
Regular cleaning is essential for keeping quartz counters shiny. Daily wiping with a damp microfiber cloth removes surface dust and spills that can dull the finish if allowed to accumulate. For deeper cleaning, use a nonabrasive quartz cleaner or mild soap and water. Avoid abrasive cleansers, pads, and scrubbing tools that could scratch the surface.
Vinegar, ammonia, bleach, and other harsh chemicals can damage and discolor quartz. Check product labels and only use cleaners specifically formulated for quartz and engineered stone. Spray the cleaner directly onto a soft cloth or sponge rather than the counter itself to prevent pooling.
Address Stains Promptly
Quartz resists stains better than marble or granite. However, spills like wine, coffee, and tomato sauce can stain if left overnight. Blot wet spills immediately and clean as soon as possible with a damp cloth and mild cleaner.
For dried or stubborn stains:
- Make a paste of baking soda and water and gently rub onto the stain using a soft cloth or nonabrasive sponge. Rinse and dry thoroughly after 5-10 minutes.
- Mix equal parts clear, undiluted ammonia and warm water. Apply to the stain for 2-3 minutes using a nonscratching white nylon pad. Rinse well and wipe dry.
- Try a hydrogen peroxide-based cleaner specifically formulated for quartz counters and let sit for 2-3 minutes before wiping.
Avoid applying excessive pressure and never use harsh chemicals like bleach, vinegar, abrasives, or acidic/alkaline cleaners on stains as these can permanently damage the finish. Contact a professional if stains remain after multiple cleaning attempts.
Handle Spills Wisely
What you do immediately after a spill can determine whether a permanent stain forms:
- Blot liquids right away – Don’t let spills sit. Quickly soak up as much as possible using a clean, dry cloth or paper towels.
- Flush with water – For spills like coffee, tea, wine, and tomato-based products, rinse the area with warm water to dilute staining pigments after blotting.
- Use baking soda – For grease spills, blot then sprinkle baking soda on the area to absorb residue. Let sit for 10 minutes before wiping and rinsing clean.
- Avoid abrasives – Do not rub the spill aggressively with abrasive pads or scrubbers which can damage the finish.
- Dry thoroughly – After cleaning, dry the area with a soft cloth to prevent water spots.
Prevent Heat Damage
While quartz counters can tolerate brief exposure to moderate heat, excessive or prolonged direct heat from pots, pans, and appliances can damage the solid acrylic resins that give quartz its shine and durability. To prevent discoloration, cracking, and loss of luster:
- Always use trivets, hot pads, and cutting boards when placing hot cookware on quartz counters.
- Don’t put electric skillets, slow cookers, or other small appliances directly on quartz surfaces.
- Avoid exposing quartz near ovens and stovetops to temperatures above 150°F for over 10 minutes.
- Never place quartz sinks, vanities, or shower walls close to heat sources like blow dryers, curling irons, and candles to prevent scorching.
- Let cookware cool before placing directly on quartz counters after cooking.
- Clean up any spills from high-temperature liquids like boiling water or hot oil immediately. Prolonged heat exposure in localized areas can damage quartz.
Quartz counters are nonporous and do not require sealing like natural stone. However, periodic resealing every 2-3 years can refresh the glossy top coat and help maintain a like-new appearance. Use a dedicated quartz resealing product for the best results. Clean the counters thoroughly, apply the sealer evenly according to product directions, allow proper drying time, then buff with a soft cloth until shiny.
Perform Deep Cleaning Routinely
In addition to daily maintenance, deep clean quartz surfaces 1-2 times per month to remove accumulated residues that cause dulling over time. Mix a few drops of mild dish soap with warm water in a spray bottle. Spray directly onto quartz then wipe clean using a soft microfiber cloth, changing rags frequently to prevent redeposition of dirt. Rinse well and dry with a fresh cloth.
For counters with more grime buildup, use a specialized quartz cleaner designed for periodic deep cleaning. Apply the product in circular motions using a nonabrasive cleaning pad. Rinse thoroughly and dry the counters completely afterward. Avoid using excessive force when scrubbing.
Address Minor Scratches
Quartz counters are highly scratch resistant, but not fully scratch proof. Light surface scratches can develop over time from cutting, aluminum pans, jewelry, and other daily wear and tear. Fortunately, minor scratches are usually superficial and can be minimized by:
- Using a quartz polish or performing a deep clean to remove debris caught within scratches.
- Rubbing a wet Mr. Clean Magic Eraser very gently over scratches to buff them out.
- Applying a thin layer of clear paste wax with a microfiber cloth, allowing it to dry, then buffing in circular motions.
- Having a professional lightly polish with 220-400 grit wet-dry sandpaper followed by a quartz-specific epoxy resin repair kit.
Prevent future scratches by using cutting boards, avoiding metal cookware, keeping counters free of debris, and being careful not to drag heavy, abrasive objects across surfaces.
Know Your Warranty Coverage
Reputable quartz manufacturers offer 10-15 year warranties guaranteeing against defects in materials and craftsmanship. Make sure you understand warranty terms, exclusions, claim procedures, and coverage duration from your fabricator or installer. Damage from abuse, misuse, improper maintenance, and exposure to extreme heat is often excluded from coverage. Keep your sales paperwork, order confirmation, and warranty information accessible in case you need to file a claim for manufacturer defects down the road.
Call a Professional for Significant Damage
For more severe damage like deep gouges, cracks, chips, and obvious signs of overheating, do not try extensive DIY repairs. Call the professional fabricator or installer who did your original quartz installation. Improper repair techniques and products can make damage worse and often void warranties. The right pros have specialized tools, materials, and techniques to restore quartz surfaces and make permanent repairs while retaining the integrity and appearance of your counters.
