Care and Maintenance
The BLANCO SILGRANIT material is engineered for durability and ease of maintenance. Its non-porous, smooth stone surface resists scratches, stains, and heat, making it simple to clean.
General Cleaning:
- For daily cleaning, use a mild dish soap and a soft cloth or sponge. Rinse thoroughly with water.
- To remove scuff marks or stubborn stains, BLANCOCLEAN SILGRANIT Sink Cleaner is recommended. Follow the product instructions for best results.
- Avoid abrasive cleaners, steel wool, or harsh chemicals (e.g., drain cleaners containing sulfuric acid) as these can damage the surface.
- Rinse the sink after using any cleaning agents to prevent residue buildup.
Preventative Measures:
- While SILGRANIT is highly resistant to heat, avoid placing extremely hot pots or pans directly on the surface for extended periods. Use a trivet or the included accessories.
- Prevent prolonged contact with highly acidic or alkaline substances, as these can potentially affect the finish over time. Rinse immediately if contact occurs.

This section addresses common inquiries and minor issues you might encounter with your BLANCO Inteos sink. For complex problems, please contact customer support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Water spots or mineral buildup | Hard water residue | Wipe the sink dry after each use. For existing buildup, use a diluted vinegar solution or a specialized descaler, then rinse thoroughly. |
| Faint scratches or scuff marks | Normal wear or contact with abrasive items | SILGRANIT is highly scratch-resistant. For minor marks, use BLANCOCLEAN SILGRANIT Sink Cleaner and a non-abrasive sponge. |
