How Do I Protect My Quartz Counter Countertops?

Quartz countertops are an increasingly popular choice for kitchen and bathroom remodeling projects thanks to their durability, low maintenance, and stylish appearance. However, like any surface, quartz requires some care and maintenance to keep it looking pristine. Here is a comprehensive guide on how to protect and care for quartz countertops to help them retain their beauty for years to come.

Cleaning Quartz Countertops

Regular cleaning is the first step in protecting quartz counters. Here are some best practices:

Use Mild Cleaners

Avoid abrasive cleaners or anything acidic like vinegar, lemon juice, etc. These can etch or dull the surface over time. Instead, clean quartz with mild dish soap and warm water using a soft cloth or sponge. Rinse thoroughly after cleaning.

Daily Wipe Downs

Wipe up spills immediately to prevent staining, especially oils, wines, tomatoes, mustard etc. A quick daily wipe down with a damp microfiber cloth reduces buildup.

Deep Clean Weekly

Once a week, give the counters a thorough cleaning using a gentle quartz cleaner or all-purpose cleaner diluted with water. Clean grout lines with a soft bristled brush. This regular maintenance keeps quartz looking like new.

Avoid Bleach and Ammonia

Never use cleaners containing bleach, ammonia, alkalis or hydrofluoric acid as these can pit and discolor the finish.

Use a Limestone/Marble Cleaner

Look for a specially formulated limestone/marble cleaner which are safe for quartz but powerful enough to deep clean without dulling the finish.

Prevent Soap Scum Buildup

Soap and minerals in water can leave a cloudy film over time. Use a squeegee after washing dishes to remove excess water and promote quicker drying.

Protecting Against Heat Damage

Quartz is engineered to be more heat resistant than natural stone. However, prolonged direct heat exposure can still damage the solid acrylic-polyester resin binder causing cracks and discoloration. Follow these tips to avoid thermal shock:

Use Trivets and Hot Pads

Place trivets, hot pads or cooling racks beneath hot pans, baking sheets, casserole dishes etc. removed directly from the oven or stove top. Never set them directly on the quartz.

Don’t Leave Hot Appliances

Avoid leaving hot hair tools, crock pots, griddles, instant pots or other electrical appliances directly on the counter. The prolonged heat can penetrate the stone.

Install Backsplashes

Backsplashes protect wall edges above ranges, ovens, and cooktops from splatters than can heat and discolor quartz. Full backsplashes of tile or other non-combustible material provide the best protection.

Don’t Pour Boiling Liquids

Always allow tea kettles, pots of boiling water etc. to cool slightly before emptying over a quartz sink. Thermal shock from rapid temperature changes can damage the material.

Avoid Flambéing

Flambéing food requires igniting alcohol which produces an open flame right on the counter. Choose another prep area for this cooking technique.

No Hot Pans from Oven/Broiler

When broiling meat or pulling hot pans from a hot oven, use thick mitts and set them on a trivet or rack to cool – never directly on quartz.

Limit Candle Use

Avoid leaving lit candles or sterno warmers in close proximity to the countertop. The open flame heats the surrounding stone.

Check Appliance Manuals

Some appliances like instant pots, air fryers etc. specifically warn against use on quartz and solid surface countertops due to excessive heat output. Always check manuals.

Preventing Scratches and Nicks

Quartz stands up remarkably well to daily wear and tear. However, extremely sharp objects can scrape, scratch or nick the surface. Here are some precautions:

Use Cutting Boards

Never cut or chop directly on the counter. Always use a cutting board to protect from knife marks.

Limit Abrasive Scouring

Aggressive scouring with steel wool, hard sponges, or abrasive cleansers can wear down the finish over time. Use gentle pressure with soft sponges/cloths.

Install Edge Guards

Metal edge guards protect exposed corners against nicks from metal cookware, keys, tools etc. Great for heavy traffic areas like near the stove or sink.

Avoid Harsh Chemicals

Do not use paint removers, turpentine, nail polish remover or drain cleaners on quartz which can remove the polish.

Lift Don’t Drag Items

Lifting objects prevents scratching the surface. Never drag pots, appliances, tools, etc. which can scrape quartz.

Use Placemats and Trivets

Placemats protect from ceramic dishes, cast iron pots etc. scratching the surface. Trivets also prevent thermal cracks.

Don’t Pound or Cut on Surface

Avoid hammering meat or using quartz as a makeshift chopping block. This high impact can chip the edges. Always use a hardwood board.

Clean Under Appliances

Regularly clean under small appliances to prevent dirt and debris buildup from causing abrasions and scratches.

Install Buffered Cabinet Bumpers

Self-adhesive clear cabinet bumpers prevent doors and drawers from banging into countertops and chipping the edges.

Apply Sealants Near Sinks

Special quartz sealants add extra protection against etching and pitting near sinks prone to exposure from acidic foods and soaps. Reapply sealants periodically.

Preventing Stains and Discoloration

The non-porous nature of quartz makes it resistant to most stains. However, prolonged exposure to certain substances can cause discoloration that requires professional removal. Here are some tips to avoid stains:

Immediately Clean Spills

Quickly wipe up wine, coffee, oil, and other staining substances. Dried on residue increases staining risk.

Avoid Long Contact with Iron

Cast iron pans and cookware can leave a metallic stain if left on quartz. Always use trivets and promptly wipe up rusty water.

Clean Up Grease Splatter

Grease splatters near stoves need frequent cleaning. Built up grease residue can penetrate the surface.

Don’t Allow Food to Rot

Leaving acidic produce like lemons, limes or tomatoes on the counter for extended periods increases etching risks. Wipe up decaying food immediately.

Use Coasters for Beverages

Coasters prevent glass rings and moisture underneath drinks. Condensation can penetrate joints and seams.

Remove Nail Polish Promptly

Don’t use quartz as a work area for manicures. Nail polish and remover contain staining and damaging chemicals.

Clean Pet Accidents Thoroughly

Pet urine contains urea which can yellow and etch quartz. Blot up accidents immediately and sanitize with an enzyme cleaner.

Avoid Long-Term Dyes and Pigments

Prolonged contact with fabric dyes, colored cosmetics, latex and oil paints, permanent markers etc. can stain quartz. Wipe up promptly.

Use Sealants Near Cosmetic Areas

Sealants provide added protection on surfaces near sinks to prevent makeup stains around bathroom vanities.

Protect from Excess Sunlight

Direct ultraviolet light can slowly discolor some quartz varieties. Limit sun exposure with window treatments.

Preventing Damage from Impacts and Drops

Quartz is highly impact resistant thanks to its durable engineered composition. However, excessive force can cause chips, cracks, and breakage. Follow these guidelines:

Handle Heavy Objects with Care

When setting down heavy pots, appliances, etc., set them down gently. Dropping them from even a short distance can crack quartz at impact points.

Avoid Hard Impacts Near Edges

Hitting quartz edges with hard objects like tools, pans, etc. can chip the material. Be especially careful near cut out areas for sinks.

Supervise Kids Around Quartz

Children playing near counters can chip quartz with hard toys. Monitor play areas and avoid quartz use in high traffic kids’ spaces.

Pad Counters Near Stovetops

Padded counter mats around stoves prevent pot lids, utensils and heavy pans from forcefully hitting the surface.

Install Reinforcement Brackets

Reinforcement brackets underneath overhangs and unsupported spans provide extra impact protection against heavy dropped items.

Avoid Moving Heavy Appliances

Dragging heavy stand mixers, microwaves etc. across the surface can crack or chip the material. Always lift objects to reposition them.

Handle Plates and Dishes with Care

Rough loading of dinnerware and cookware can crack sink areas and chip countertop edges. Avoid slamming and use care unloading dishwashers.

Immediately Remove Broken Glass

Sweep up broken glassware immediately to prevent abrasive shards scratching the surface if dragged across the counter.

Don’t Pound Surfaces

Never pound on the surface with fists, tools, etc. The impact can damage the solid acrylic-polyester resin structure.

Caring for Quartz Sink Areas

Quartz sinks require some special care given their frequent exposure to staining substances, impacts, and temperature changes:

Avoid Abrasive Scouring

Aggressive scrubbing with abrasive pads or harsh cleansers can gradually wear down the glossy finish inside sinks. Use soft sponges/scrub brushes.

Minimize Temperature Shock

Avoid pouring boiling water directly from kettles and pots which causes rapid temperature changes and thermal shock. Allow hot liquids to slightly cool first.

Use Bottom Racks for Dishes

Load dishes on the lower rack inside dishwashers so hot circulating water doesn’t directly contact quartz sink basins during drying cycles.

Apply Sealants Periodically

Sealants provide added protection from staining and etching inside frequently used sinks. Reapply every 6 months.

Handle Sink Areas Gently

Avoid rough handling of heavy pots, cast iron pans, etc. around vulnerable sink cutouts which can chip from impact.

Keep Chemicals Away From Sink

Store harsh drain cleaners and chemical cleaning products well away from sink areas to prevent acidic etching if splashed.

Install Reinforcement Brackets

Metal reinforcement brackets adhere underneath sink cutouts to provide better structural support and impact resistance from heavy falling pots and pans.

Use a Bottom Grid

Plastic bottom grids protect sink basins from scratches when washing dishes. Remove grids to fully clean the basin weekly.

Clean Disposal Flanges

Remove and thoroughly clean sink disposal flanges regularly to prevent leaking rotten food from staining sink areas.

Loosen Calcium Buildup

Remove hard water calcium deposits frequently using vinegar or limescale removers to prevent permanent etching around faucets.

Protecting Against Joint Damage

Quartz countertops are made from slabs joined together. Proper care of seams and joints prevents moisture damage or separated laminations:

Clean and Dry Joints

Wipe joints and seams after spills or cleaning to prevent moisture penetration. Pay special attention near sinks.

Apply Joint Sealants

Special sealants designed for quartz joints block moisture and weepage between slabs. Reapply every 1-2 years.

Avoid Excess Moisture Near Joints

Position small kitchen appliances that release steam like rice cookers away from seams to limit moisture exposure and potential damage.

Don’t Overload Near Joints

Avoid excessive weight which can stress and separate quartz slabs. Do not park yourself on joints or apply heavy impact forces.

Check for Separations

Inspect joints periodically and look for any separations between slabs which indicate damaged caulking. Have them resealed immediately.

Get Annual Inspections

Have a countertop professional inspect seams annually and reapply joint sealants or epoxies as needed to maintain moisture protection.

Limit Vegetable Prep Near Joints

The acids in cut fruits and veggies can penetrate joints, damaging caulk over time. Avoid excessive food prep directly on seams.

Use Trivets Near Seams

Setting hot pots and pans directly on joints risks heat damage to underlying caulk. Use trivets and hot pads.

Clean Up Spills Quickly

Liquid spills migrate down joints easily. Wipe up moisture immediately to avoid ingress around vulnerable quartz seams.

Professionally Repairing Any Damage

Quartz holds up very well, but chips, nicks, scratches, discoloration or heat damage can occasionally occur. Trust a professional fabrication shop for expert repairs:

Spot Treat Minor Stains

Light stains can often be removed by a pro using a buffing compound or poultice to pull out discoloration.

Sand and Refinish Scratches

Light scratches can be sanded down and buffed out. More severe scratches may require refinishing the entire surface.

Use Color-Matched Fillers on Chips/Cracks

Small chips and cracks can be filled with color-matched epoxy resin fillers ground and polished flat.

Heat Damage Requires Polishing

Areas discolored or damaged by thermal shock may need extensive mechanical polishing to remove the top damaged layer.

Cut Out and Replace Severe Damage

Badly damaged sections may need to be cut out and seamlessly replaced with a new quartz piece by an experienced pro.

Recaulk Seams if Needed

Separated or cracked seams require cleaning out old caulk and complete re-sealing for water protection.

Bleach Stains If Possible

Stubborn stains from dyes or chemicals may be bleached out using professional products. Avoid DIY bleaching.

Grind Down Stubborn Marks/Scratches

Deep scratches or scorched areas often require grinding the surface with diamond pads and re-polishing.

Seek Professional Help

Do not attempt DIY spot repairs. Always hire an experienced quartz fabricator/installer for proper repairs.

Maintaining Quartz’s Flawless Finish

Quartz comes from the factory with a beautifully polished, glossy finish. Proper care maintains the gloss and light reflective quality:

Clean With Non-Abrasive Cleaners

Using mild cleaning products avoids wearing down the factory sheen over time. Abstain from using abrasive scouring pads or powders.

Increase Cleaning Frequency Near Cooktops

Frequently degrease and disinfect surfaces near stoves and ranges to prevent buildup of greasy residue that can dull quartz.

Use Sealants and Finishing Products

Sealers and finishing sprays add an extra layer of protection and enhance the glossy appearance. Reapply finishing products periodically.

Address Minor Scratches Quickly

Have minor scratches professionally buffed out before they become more severe issues requiring refinishing.

Do Not Refinish at Home

Avoid DIY refinishing or mechanical polishing which requires professional equipment to match the original polish and finish.

Replace Severely Damaged Sections

Badly damaged areas may need replacement to match the pristine factory finish. Professionals can replace sections seamlessly.

Increase Humidity Near Counters

Low humidity can make quartz appear dull and dry. Use humidifiers during winter months to keep moisture levels higher.

Have Professionals Handle Issues

Don’t sand, buff or refinish quartz yourself. Always hire reputable fabricators to address any finish issues.
