How to Care for Black Quartz Countertops

Black quartz countertops can add dramatic beauty and style to any kitchen or bathroom. However, like all countertop materials, they require some basic care and maintenance to keep them looking their best. Here is a comprehensive guide on how to care for black quartz countertops.

Cleaning Black Quartz Countertops

  • Use a mild soap and warm water. Avoid abrasive cleaners or pads that could scratch the surface.
  • For dried spills, use a non-abrasive scrubbing sponge. Apply pressure evenly to avoid scratching.
  • For stuck-on messes, spray with an all-purpose cleaner and let sit for 5 minutes before scrubbing gently. Avoid acidic or bleach cleaners.
  • Rinse thoroughly after cleaning and wipe completely dry with a soft cloth. Residual moisture can damage sealants.
  • For polishing, use a specially formulated quartz countertop polish to enhance shine and repel dirt. Avoid wax-based polishes.
  • Disinfect periodically with diluted bleach – 1 part bleach to 10 parts water. Rinse off thoroughly.

Preventing Damage to Black Quartz Countertops

  • Always use cutting boards, trivets and coasters under hot pans or dishes to prevent burning.
  • Don’t cut directly on the counter. Use a cutting board to protect the surface.
  • Avoid harsh chemicals like paint removers, oven cleaners, etc. Check product labels for safety first.
  • Be gentle with heavy impact. Dropping a heavy object may crack the quartz.
  • Reseal with a penetrating sealer annually to refresh water repellency and stain resistance.
  • Blot spills quickly to prevent staining, especially from juices, wines or acidic foods.

Repairing Damage to Black Quartz Countertops

  • Light scratches can be buffed out with a rubbing compound designed for quartz.
  • For darker scratches, sand lightly with 600 grit sandpaper, then buff with compound.
  • Small chips or cracks can be filled in with a quartz repair or chip fill kit. Follow kit directions carefully.
  • For seam gaps, use clear silicone caulk that matches the countertop’s color. Remove old caulk before reapplying.
  • For burnt marks, carefully sand the spot with 220 grit sandpaper. Be careful not to alter the surrounding finish.
  • For stubborn stains, make a poultice with household cleaner and paper towels to draw out the stain. Rinse thoroughly after.
