Daily Cleaning for Easy Maintenance

Daily cleaning is important for the effortless maintenance of your granite composite sink to effectively prevent the accumulation of stubborn stains. To tackle this task, simply usewarm and soapy water along with a gentle sponge or cloth for a thorough yet gentle scrubbing action.

Deep Cleaning for Tough Stains

For tougher stains or limescale build-up, a deeper cleaning regimen becomes necessary to restore the sink’s original luster.

Option 1: Baking Soda and Vinegar Paste

Cleaning granite composite sink is simple and effective with baking soda and vinegar paste. To create a paste: 

  • Begin by mixing equal parts of baking soda and water in a small bowl until a thick paste forms.
  • Once the paste is ready, apply it generously to the surface of the sink, focusing on areas with tough stains or limescale build-up.
  • Allow the paste to sit on the surface for about 15 to 20 minutes, allowing the baking soda to work its magic on the stubborn stains.
  • After the settime has passed, gently scrub the sink with a non-abrasive sponge or brush, using circular motions to lift off the stains effectively.
  • Once satisfied with the scrubbing, rinse the sink thoroughly with warm water to remove any residue of the paste, ensuring a clean finish.
  • Finally, dry the sink with a clean towel to prevent water spots and maintain its pristine appearance.

Option 2: Vinegar Solution

For an alternative approach, consider utilizing a diluted white vinegar solution, typically mixed in a 50/50 ratio with water.

  • Begin by spraying this solution directly onto areas affected by limescale or tough stains, ensuring thorough coverage.
  • Allow the vinegar solution to soak into the surface for approximately 10 to 15 minutes, allowing its acidic properties to break down the build-up effectively.
  • Following the soaking period, gently scrub the sink using the non-abrasive side of a sponge, applying moderate pressure to lift off the loosened deposits.
  • Once the scrubbing is complete, rinse the sink with warm water to eliminate any lingering vinegar residue to ensure a fresh and clean finish.
