Operating the Sink
The BLANCO ETAGON 6 sink is designed for versatile use in your kitchen, leveraging its unique step concept and included accessories.
Multi-Level Functionality:

- Middle Level: The integrated step within the sink bowl provides a middle level. This can be used to rest smaller items, or to support a second set of rails or accessories for additional functionality.
- Bottom Level: The main basin serves as the primary washing area for larger pots, pans, and general dishwashing.
Drain Operation:
The sink features a 3 ½ inch InFino basket valve with a comfortable rotary operation for controlling the drain. Rotate the knob located on the tap bench to open or close the drain, allowing for easy filling or emptying of the sink.
Maintenance and Care
To ensure the longevity and pristine appearance of your BLANCO ETAGON 6 Silgranit sink, follow these simple maintenance guidelines:
- Daily Cleaning: After each use, wipe the sink surface with a dry cloth to prevent water spots and mineral buildup.
- Stain Removal: For tougher stains, use a mild dish soap and a soft sponge or cloth. Avoid abrasive cleaners, scouring pads, or harsh chemicals, as these can damage the Silgranit surface.
- Heat Resistance: While Silgranit is heat-resistant, it is always recommended to use a trivet or hot pad for extremely hot pots and pans to protect the surface from potential thermal shock or discoloration over time.
- Scratch Resistance: Silgranit is highly scratch-resistant, but avoid dragging sharp or heavy objects across the surface to maintain its finish.
- Preventing Limescale: In areas with hard water, limescale deposits may form. Regular cleaning with a descaling agent specifically designed for kitchen sinks or a solution of vinegar and water can help prevent buildup. Rinse thoroughly after using any cleaning agent.
Proper care will keep your BLANCO Silgranit sink looking new for years to come.
