Guide to Cleaning and Maintaining Quartz Countertops

How Quartz Differs from Natural Stone

Quartz countertops are approximately 90 percent ground quartz crystals and 10 percent polymer resins and pigments. Unlike granite, which is porous and requires sealing, quartz is non-porous — meaning it does not absorb liquids. This makes it highly resistant to staining from typical kitchen spills.

However, the resin component is what makes quartz vulnerable. High heat can discolor or crack the resin. Harsh chemicals can break down the resin and dull the surface. And while quartz does not absorb most liquids, certain substances — particularly permanent marker, hair dye, and strong food coloring — can bond to the resin surface if left in contact too long.

Daily Cleaning: Simple and Effective

Quartz requires nothing more than basic daily cleaning to stay in excellent condition:

1. Wipe down with a soft cloth or sponge dampened with warm water
2. For food residue or grease, add a small amount of mild dish soap
3. Rinse the cloth and wipe again to remove soap residue
4. Dry with a clean cloth to prevent water spots

This four-step routine is genuinely all you need. Quartz does not need special cleaners, polishes, or sealers. The simpler your daily approach, the better the surface performs long-term.

Products That Damage Quartz

These products should never come in contact with quartz countertops:

• Bleach, oven cleaner, and drain cleaner — the harsh chemicals break down the resin bond
• Abrasive cleaners like Comet or Ajax — the gritty particles scratch the surface
• Concentrated vinegar or pure lemon juice in extended contact — mild acids can etch the resin over time
• Permanent markers, paint, nail polish — these bond to the resin if not wiped immediately
• Steel wool, scouring pads, or rough scrub brushes — they scratch and dull the finish

Removing Stubborn Stains

Dried Food and Hard Water Deposits

Gently scrape with a plastic putty knife to remove the bulk, then clean with a soft cloth and dish soap. For hard water rings from glasses, a paste of baking soda and water applied gently with a soft cloth usually removes the deposit without scratching.

Permanent Marker or Dye Stains

Apply rubbing alcohol to a cloth and place it on the stain for several minutes. The alcohol dissolves the pigment without affecting the quartz. Wipe clean and rinse. For particularly stubborn marks, Goo Gone is safe on quartz when used sparingly and rinsed thoroughly.

Long-Term Quartz Care

• Use cutting boards — while quartz resists scratching better than most surfaces, sharp knives can leave marks
• Use trivets for hot cookware — always, without exception
• Clean spills promptly — quartz resists staining but is not stain-proof against all substances
• Avoid direct sunlight exposure for extended periods — UV can cause discoloration of the resin over time

With proper care, quartz countertops maintain their appearance for 15 to 25 years. If your countertops have developed a dull appearance from improper cleaning product use, a professional deep clean can strip the buildup and restore clarity without damaging the surface.
