How to Clean and Care for Quartz Countertops (and What Damages Them)

Quartz is one of the most popular countertop choices in Calgary homes because it's tough, non-porous and never needs sealing. But low-maintenance isn't the same as no-maintenance. The wrong cleaner or one hot pan can leave marks that won't wipe off.

Here's how to clean quartz day to day, what to keep off it, and what to do if it does get damaged.

Why quartz needs different care

Quartz countertops are engineered, not cut from a single slab of rock. They're made of roughly 90% ground natural quartz bound together with polymer resins and pigments.

The stone part is extremely hard and resists scratches. The resin is what makes quartz non-porous, but it's also the weak point.

Resin can scorch under high heat, break down under harsh chemicals, and yellow with long sun exposure. Most quartz damage we repair traces back to the resin, not the stone.

Daily cleaning routine

Warm water, a few drops of mild dish soap and a soft cloth handle almost everything.

1. Wipe up spills as they happen, especially wine, coffee, oil and tomato sauce.
2. Wash the surface with warm, soapy water and a soft cloth or non-scratch sponge.
3. Rinse with a clean damp cloth so soap doesn't leave a film.
4. Dry with a microfibre towel to avoid water spots, which show up easily with Calgary's hard tap water.

For a little extra shine, use a cleaner labelled safe for quartz. Skip anything that promises to "seal" or "polish" stone. Quartz doesn't need it, and the residue can leave a hazy film.

What to keep off your quartz

These are the habits and products behind most of the quartz damage we see.

• Hot pots, pans and slow cookers set directly on the surface
• Bleach, oven cleaner, drain cleaner, paint stripper
• Abrasive powders and scouring pads
• Cutting directly on the counter
• Dropping heavy pots or cast iron near edges
• Standing or kneeling on the counter
• Long direct sunlight (outdoor kitchens, south-facing windows)

Always use trivets or hot pads, and cutting boards. They're the two cheapest ways to avoid a repair bill.

Removing stubborn stains and dried-on messes

Because quartz is non-porous, most "stains" are sitting on the surface and come off with the right approach.

• Dried food, gum or paint: Soften with warm soapy water, then lift gently with a plastic scraper or old gift card. Never use a metal blade.
• Grease and cooking oil: Use a degreasing dish soap or a cleaner labelled safe for quartz.
• Coffee, tea, wine and juice: Make a paste of baking soda and water, leave it on for a few minutes, then wipe off with a soft cloth.
• Marker or ink: Dab with a little isopropyl rubbing alcohol on a cloth, then rinse with water.
• Hard water spots: Wipe with diluted white vinegar (about 1 part vinegar to 3 parts water), rinse right away and dry. Don't leave vinegar sitting on the surface.

If a mark doesn't budge after a couple of tries, stop scrubbing. A burn or etch can look like a stain, and scrubbing harder will only dull the area around it.

If damage happens

Chips, burns and scratches in quartz can usually be repaired in place, without pulling out the countertop.

• Chips: The damaged spot is cleaned, filled with a resin tinted to match your quartz, then shaped and polished flush with the surface.
• Burn marks: Light scorching can often be sanded and polished out. Deeper burns are filled and colour-matched like a chip.
• Scratches and dull areas: These are buffed out with progressively finer polishing pads to bring back the original sheen.
• Cracks and open seams: These are cleaned, filled and bonded. A crack that keeps growing may point to a support problem underneath, which should be fixed first.

Avoid DIY epoxy kits on quartz. A poor colour match or uneven fill is hard to undo and can make a professional repair harder later.

Frequently asked questions

Do quartz countertops need to be sealed? No. Quartz is non-porous, so sealers have nothing to soak into and can leave a sticky film.

Can I use disinfecting wipes on quartz? Occasional use is generally fine, but many wipes contain bleach or harsh chemicals. For daily cleaning, mild soap and water is safer. Rinse afterward if you do use wipes.

Is quartz heat resistant? Only somewhat. The stone handles heat, but the resin can scorch. Always use a trivet under hot pots, pans and appliances.

Can a burn mark on quartz be fixed? In most cases, yes. Light burns can often be polished out, and deeper ones can be filled and colour-matched.

Will a repair be visible? A well-done repair on a solid-colour or lightly speckled quartz is very hard to spot. Heavily veined patterns are more challenging, but a good colour match still blends in from normal viewing distance.
