5. Maintenance and Care

Proper care will help maintain the appearance and performance of your KRAUS Quarza sink.

5.1 Daily Cleaning

The smooth, non-porous surface resists stains and is easy to clean. Gently rounded corners minimize build-up. For daily cleaning, wipe the sink with a soft cloth and mild soap or a non-abrasive cleaner. Rinse thoroughly and wipe dry with the included kitchen towel or a soft cloth to prevent water spots.

5.2 Heat Resistance

The quartz composite material is heat-safe up to 500°F. However, placing hot items over 500°F directly onto the sink surface may cause discoloration. Always use a trivet or hot pad for items straight from the stove or oven to avoid potential damage.

5.3 Drain Assembly Care

The included drain assemblies feature removable strainers to help prevent debris from entering the drainpipe and causing clogs. Regularly remove and clean the strainers to dispose of food waste.

6. Troubleshooting

• Water Spots: If water spots appear, ensure you are wiping the sink dry after each use. For stubborn spots, a mild vinegar solution can be used, followed by thorough rinsing.
• Clogging: Regularly clean the drain strainers to prevent food particles from accumulating. If a clog occurs, use a non-corrosive drain cleaner or consult a plumber.
• Discoloration: Avoid placing extremely hot items (over 500°F) directly on the sink. For minor discoloration, specialized granite composite cleaners may help, but always test in an inconspicuous area first.
