Quartz is a popular choice for beautiful kitchen countertops thanks to its durability, style, and resistance to stains. Unlike natural stone surfaces, it's engineered to be nonporous – that means it doesn’t absorb liquids or stains (no, never). This makes it incredibly easy to clean and maintain; however, while quartz doesn’t stain in the traditional sense, if you don't wipe spills quickly, certain residues, like coffee, wine, or permanent markers can leave marks that require a little bit of extra attention.

Regular Cleaning vs. Deep Cleaning

For most messes, everyday cleaning is enough to keep quartz surfaces sparkling. When spills like coffee or wine aren’t wiped up immediately, or when caulk or silicone around the edges starts to discolor, you might need to do a little more. The trick is using gentle products that won't damage the surface or its resin binder.

Everyday Cleaning Tips

  • Wipe down the countertop daily with a soft microfiber cloth and warm water.
  • Use a mild dish soap for grease or sticky spills.
  • Avoid abrasive cleaners like scouring pads which can damage the smooth surface.
  • Avoid acidic cleaners (vinegar), or alkaline solutions (bleach or stain removers), as these can dull the surface. This includes disinfectant wipes that often have these components.
  • Dry with a clean towel to prevent water spots.

Cleaning Wine and Coffee Marks

  • Warm, Soapy Water: The simplest non-abrasive cleaner is dish soap or mild detergent in warm water. Dampen a cleaning cloth or a non-abrasive sponge, and gently scrub the mark in a circular motion.
  • Baking Soda Paste: For tougher stains and marks, make a paste with baking soda and water. Apply it to the spot, let it sit for 5-10 minutes, and wipe away with a damp cloth.
  • Glass Cleaner: Spray a glass cleaner directly on the mark and wipe clean with a microfiber cloth. Wipe with clean water before starting any food preparation.
  • Specialized Quartz Cleaner: Many manufacturers sell specifically formulated cleaners for quartz countertops. These can help remove stubborn marks without risk of potential damage.

Stained caulk or silicone? Try This

  • Rubbing Alcohol: Dampen a cotton ball or cloth with isopropyl alcohol and gently scrub the stained area.
  • Plastic Scraper: For dried-on residue, carefully use a plastic putty knife or scraper to remove the discolored caulk or silicone.
  • Replace Caulk: Whether from damage over time or if a stain persists, you may need to remove the old caulk and apply new, matching silicone for a fresh look.
  • Avoid Harsh Chemicals: Do not use cleaning products containing bleach or acetone, as these harsh cleaners can damage the surrounding quartz.

FAQ

Why does my quartz countertop look dull or cloudy?

A dull or cloudy appearance on quartz countertops is often caused by soapy residue from cleaning products or water stains from hard water buildup. To restore the shine, clean the surface with warm water and a gentle cleaning product then wipe it dry with a dry cloth. Avoid using waxes or polishes, as these can create a hazy film over time. If the issue persists, consider using a quartz-specific cleaner to remove the excess buildup of dirt or oil safely.

What should I do if I accidentally use an abrasive cleaner on quartz?

Quartz is a durable material but it can get scratched. If you’ve used an abrasive cleaner, inspect the surface for any dull or scratched areas. To restore its shine, clean the area with warm water and a mild soap, then buff gently with a soft cloth. For significant damage, consult a quartz countertop professional to assess the surface.

Is sealing necessary for quartz countertops?

No, quartz countertops do not need to be sealed because they are nonporous. Unlike natural stones like granite or marble, quartz kitchen countertops are engineered to resist stains and bacteria without requiring sealants. That being said, they will always benefit from routine care and common sense to stave off normal wear and tear.
