What You’ll Need

Before You Start

  • Clear the countertop of everything removable.

  • Allow it to sit for 5-10 minutes.
  • Wipe the countertop down with a clean, damp sponge.
  • Rinse thoroughly and wipe dry with a soft cloth.
  • Repeat as needed for any remaining haze.

Protecting and Sealing the Quartz

  • Once fully clean, apply a penetrating quartz sealer to protect the surface.
  • Allow the sealer to fully cure for 24-48 hours.
  • Buff with a soft cloth to remove any excess.

FAQs about Removing Grout from Quartz

How can I tell if my countertop is made of quartz?

Quartz countertops are non-porous and feel smooth and cool to the touch. They are also very hard and resistant to scratches, heat, and stains. Look for speckled or veined patterns throughout the stone.

What tools work best for removing grout from quartz?

An oscillating multi-tool with a grout removal blade is ideal. It allows you to cut into the grout joints without damaging the quartz. Grout saws and carbide grout rakes also work well.

How do I avoid scratching the quartz while removing the grout?

Work slowly and carefully. Don’t apply too much pressure with the grout saw. Wipe away any debris right away to maintain visibility. Use only plastic scrapers and soft cloths to avoid scratching.

Can I use an acidic grout cleaner on quartz?

No, you should never use acidic cleaners, including vinegar, on quartz. Acid can damage and etch the surface. Use a gentle grout haze remover specifically formulated for quartz.

How can I get grout stains off my quartz countertop?

Mix a paste of baking soda and water and gently rub it into the stains with a soft cloth or sponge. Rinse thoroughly and dry. For stubborn stains, use a non-acidic quartz polish or cleaning product.

How often should I seal my quartz countertop after regrouting?

It’s a good idea to seal quartz every 1-2 years. Sealing will help prevent stains and marks from setting into the surface. Be sure to use a sealer made specifically for quartz.
