  Maintenance Tips

  • Clean daily with mild soap + soft sponge – Preserves the smooth quartz composite surface and prevents dull buildup.
  • Rinse and dry after use – Helps avoid water spots and keeps the deep black finish looking consistent.
  • Avoid harsh chemicals – No bleach, ammonia, or acidic cleaners; they can damage the surface and fade the finish over time.
  • Use a sink grid or mat – Protects against scratches from heavy cookware and daily impact.
  • Clean stains quickly – Coffee, tea, and food residue should not sit long on dark granite surfaces.
  • Deep clean weekly if needed – Use baking soda paste or mild non-abrasive cleaners for stubborn marks.
  • Prevent hard water buildup – Occasional vinegar rinse helps reduce mineral deposits (rinse thoroughly after).
  • Avoid dropping heavy items – While impact-resistant, granite composite can still chip under strong force.
