Operating Instructions
The KRAUS Quarza KGD-442BLACK sink features a 60/40 double bowl configuration, designed for efficient multi-tasking in the kitchen. The larger bowl is ideal for washing substantial cookware, while the smaller, shallower bowl can be used for rinsing vegetables, staging dishes, or other preparatory tasks. The rear-set drain design maximizes usable basin space and provides additional storage under the cabinet.
Daily Use:
- Utilize the deep main bowl for soaking and washing large pots and pans.
- The secondary bowl is convenient for smaller items or for separating tasks.
- The gently sloped bottom promotes efficient draining, preventing water from pooling.

Maintenance and Care
To ensure the longevity and appearance of your KRAUS Quarza granite kitchen sink, follow these maintenance guidelines. The quartz composite material is designed for durability and ease of cleaning.
Cleaning Instructions:
- Regular Cleaning: Wipe the sink with a dry cloth after each use to prevent water spots and mineral buildup.
- Stain Resistance: The smooth, non-porous surface resists stains and can be cleaned with standard household cleaners. Avoid abrasive cleaners or scouring pads that could damage the finish.
- Rounded Corners: The gently rounded corners are designed to minimize food particle buildup, making cleaning easier.

Heat Resistance:
The sink is heat-safe up to 500°F. While it can withstand high temperatures, direct placement of items exceeding 500°F may cause surface discoloration. It is recommended to use a trivet or hot pad for extremely hot cookware directly from the stove or oven to prevent potential damage.

Color Stability:
The sink's color is stable and penetrates throughout the material, ensuring a long-lasting appearance that resists fading over time. This integral coloring helps maintain the sink's aesthetic appeal even with prolonged use.

Troubleshooting
Should you encounter any issues with your KRAUS Quarza kitchen sink, please consider the following general advice. For specific problems or complex issues, it is always best to consult the manufacturer's official support resources.
Common Concerns:
- Water Spots/Mineral Buildup: Regular wiping with a dry cloth after use can prevent these. For existing buildup, use a mild descaling solution or a mixture of vinegar and water, followed by thorough rinsing.
- Surface Scratches: While the sink is scratch-resistant, deep scratches can occur from sharp objects. Minor surface marks may sometimes be buffed out with a non-abrasive cleaner designed for granite composite sinks.
- Dull Appearance: Hard water can sometimes cause a dull film. Ensure regular cleaning and consider using a granite cleaner and polish to restore luster.
