Operating Instructions
The Kore workstation sink features an integrated ledge designed to support various accessories, enhancing your kitchen workflow.
Workstation Features:
- Integrated Ledge: Allows accessories to slide across the sink, creating a versatile workspace for meal prep and cleanup.
- Bamboo Cutting Board: Use for chopping and food preparation directly over the sink. Its non-slip design and drainage groove help contain messes.
- Roll-Up Dish Rack: Ideal for drying dishes, fruits, and vegetables, or as a trivet for hot pots and pans.
- Protective Bottom Grid: Placed at the bottom of the sink, it protects the surface from scratches and dents while promoting better drainage.
- Drain Assembly with Cover: The stainless steel drain assembly includes a removable strainer to prevent debris from entering the drainpipe. The decorative cover provides a clean aesthetic.


Maintenance
Proper care ensures the longevity and appearance of your KRAUS Kore sink.
Cleaning Instructions:
- Daily Cleaning: Wipe the sink with a dry, soft cloth after each use to prevent water spots and mineral buildup.
- Deep Cleaning: For stubborn stains, use a non-abrasive cleaner specifically designed for stainless steel. Always rinse thoroughly and dry immediately.
- Avoid: Do not use steel wool, abrasive pads, or harsh chemical cleaners (e.g., bleach, ammonia) as these can damage the satin finish.
- Accessories: Clean the bamboo cutting board with mild soap and water, and periodically treat with mineral oil to maintain its condition. The roll-up rack and bottom grid can be washed with dish soap and water.

Troubleshooting
If you encounter any issues with your KRAUS Kore sink, refer to the following common solutions:
- Water Spots/Stains: Ensure the sink is wiped dry after each use. For existing spots, use a stainless steel cleaner and polish.
- Slow Drainage: Check the drain assembly for any blockages. Ensure the sink's sloped bottom and channel grooves are clear.
- Scratches: While 16-gauge stainless steel is highly durable, minor scratches can occur over time. The included bottom grid helps minimize this. For deeper scratches, consult a professional for stainless steel refinishing.
- Noise: The sink is equipped with NoiseDefend sound dampening pads. If excessive noise is present, ensure the pads are securely attached and the sink is properly installed.
