How to Shine Black Quartz Countertops

Black quartz countertops can add dramatic beauty and elegance to any kitchen or bathroom. However, like all countertop materials, quartz requires proper care and maintenance to keep it looking its best. With the right techniques, you can keep your black quartz counters shining. Here is a comprehensive guide on how to shine black quartz countertops.

Cleaning Supplies You’ll Need

  • Microfiber cloths
  • Soft sponge or non-abrasive scrubbing pad
  • pH-neutral granite cleaner or dish soap
  • Clean water
  • High-quality granite sealer (optional)

Routine Cleaning

  • Wipe down counters daily with a soft microfiber cloth, warm water, and a small amount of pH-neutral soap or granite cleaner. This helps remove light dirt, dust, and fingerprints.
  • For stuck-on messes like dried food, grease, etc., use a non-abrasive sponge or soft scrubbing pad with your cleaner and warm water. Apply light pressure and avoid scrubbing too hard.
  • Rinse thoroughly with clean water and dry with a fresh microfiber cloth. Avoid letting water pool or dry on the surface.
  • About once a week, do a deeper cleaning using the methods above to keep counters shining.

Polishing and Protecting

  • Every 3-6 months, use a granite polish to enhance shine and help fill in micro-scratches. Apply with a soft cloth using small circular motions.
  • Reseal black quartz 1-2 times per year with a high-quality sealer to protect from stains and etching. Follow product instructions carefully.
  • Avoid abrasive cleaners, pads, or brushes as they can damage the surface over time.
  • Cutting directly on the counter without a board can also dull the surface. Always use a cutting board.

Removing Stubborn Spots and Stains

  • For dried-on food, grease, wine, coffee stains, etc., let a damp cloth soaked in dish soap sit on the spot for 5-10 minutes to loosen, then gently scrub off.
  • For stubborn stains, make a paste with baking soda and water and gently rub onto the stain with a soft cloth or sponge. Let it sit briefly before rinsing.
  • For extreme cases, a polishing compound specially formulated for quartz can help remove stains without damaging the surface. Test first in an inconspicuous area.

Avoiding Damage from Heat and Chemicals

  • Always use trivets or hot pads under hot pans, pots, plates, etc. to prevent burns. Quartz can withstand brief exposure to moderate heat but prolonged direct heat can damage the solid surface over time.
  • Avoid exposing quartz counters to very strong chemicals like paint removers, oven cleaners, etc. Rinse immediately if exposure occurs. While quartz is resistant, prolonged exposure can etch the surface.

Troubleshooting Problems

Scratches – Very light micro-scratches can be buffed out with polishing compound. Deeper scratches may require professional refinishing.

Chips – Small chips on the edges can usually be smoothed over with polishing compound. Larger chips may need professional repair.

Stains – Try stain removers first. Persistent stains may need sanding and refinishing.

Cracks – Cracks usually require professional repair. Contact a countertop specialist.
