6. Maintenance and Care
Proper care will maintain the appearance and extend the life of your Bokaiya kitchen sink.
6.1 Daily Cleaning
- After each use, rinse the sink thoroughly with water to remove food particles and residue.
- Wipe the sink surface with a soft cloth or sponge and mild dish soap.
- For the NANO brushed finish, water tends to bead and roll off, making cleaning easier and reducing water spots.
- Product Care Instructions: Wipe with a dry cloth to prevent water spots and maintain the finish.
6.2 Avoiding Damage
- Avoid using abrasive cleaners, steel wool, or harsh chemicals (e.g., bleach, drain cleaners) as these can damage the stainless steel finish.
- Do not leave acidic foods (e.g., citrus, tomatoes) or corrosive substances in the sink for extended periods.
- Use the included dish grid to protect the bottom of the sink from heavy pots and pans.
7. Troubleshooting
Here are solutions to common issues you might encounter:
7.1 Slow Drainage
- Check for Blockages: Ensure the basket strainer is clear of debris.
- X-Shape Flow Line: The sink features an X-shape flow line design to direct water towards the drain. Ensure the sink is level to maximize this feature.
- Plumbing Issues: If the sink is clear, check the P-trap and plumbing for clogs.

7.2 Excessive Noise
- Sound Dampening: The sink is equipped with thicker and softer rubber pads to minimize noise from dishes and water. Ensure these pads are intact.
- Vibration: Check if the sink is securely mounted to the countertop. Loose mounting clips can cause vibrations.
