3.1 Drain Remote Control
Your sink is equipped with a convenient drain remote control, allowing you to open and close the basket strainer without reaching into the water. Locate the rotary control knob, typically positioned on the sink deck near the faucet hole. Rotate it to operate the drain.

4. Care and Maintenance
The SILGRANIT material of your BLANCO sink is highly durable and easy to maintain. Regular cleaning will preserve its appearance and hygienic properties.
4.1 Daily Cleaning
- After each use, rinse the sink thoroughly with water to remove food particles and residue.
- Wipe the sink with a dry cloth to prevent water spots and mineral buildup, especially in hard water areas.
- For general cleaning, use a mild dish soap and a soft sponge or cloth.
4.2 Deep Cleaning and Stain Removal
- For stubborn stains, a non-abrasive cleaner specifically designed for composite sinks can be used. Always follow the cleaner's instructions.
- Avoid using harsh chemicals, abrasive pads, steel wool, or strong acids/alkalis, as these can damage the surface.
- The SILGRANIT material is scratch-resistant and impact-resistant, but it is still advisable to use cutting boards and avoid dropping heavy objects to prevent potential damage.

5. Troubleshooting
While BLANCO sinks are built for durability, minor issues may occasionally arise. Here are some common concerns and general advice:
5.1 Water Spots or Mineral Buildup
- Cause: Hard water drying on the surface.
- Solution: Regularly wipe the sink dry after use. For existing buildup, use a solution of vinegar and water (1:1 ratio) or a specialized descaling agent. Apply, let sit for a few minutes, then scrub gently and rinse thoroughly.
5.2 Slow Drainage
- Cause: Accumulation of food particles or grease in the drain.
- Solution: Ensure the basket strainer is clear of debris. For minor clogs, try pouring boiling water down the drain, followed by a mixture of baking soda and vinegar. If the issue persists, a plumbing snake or professional plumber may be required.
5.3 Fading or Discoloration
- Cause: Exposure to strong chemicals, prolonged contact with highly acidic or alkaline substances, or improper cleaning agents.
- Solution: Ensure you are using only recommended cleaning products. For persistent discoloration, contact BLANCO customer support for advice.
