2.1. Understanding SILGRANIT Material
SILGRANIT is a unique granite composite that combines the strength of natural granite with advanced engineering. This material is designed to be highly resistant to scratches, chips, and impacts, making it ideal for demanding kitchen environments. Its non-porous nature prevents the absorption of liquids and dirt, contributing to its hygienic properties and ease of cleaning.

6. Maintenance and Care
Maintaining your BLANCO PRECIS SILGRANIT sink is simple due to its durable and non-porous surface. Follow these guidelines to keep your sink looking its best:
- Daily Cleaning: Hand wash the sink regularly with mild soap and water. Use a soft cloth or sponge.
- Stain Prevention: The non-porous surface resists stains. For best results, rinse the sink thoroughly after each use to prevent food particles or liquids from drying on the surface.
- Hard Water: If you have hard water, mineral deposits may be visible, especially on darker colored sinks. To prevent this, wipe the sink dry after use. For existing deposits, use a solution of white vinegar and water, or a specialized granite composite cleaner.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, steel wool, or strong chemical agents (e.g., drain cleaners containing sulfuric acid) as these can damage the surface.
- Heat Resistance: While the sink is heat resistant up to 536°F, it is always recommended to use a trivet or hot pad for extremely hot items to prevent potential thermal shock or discoloration over time.

7. Troubleshooting
Most issues with your BLANCO sink can be resolved with proper cleaning and care. If you encounter persistent problems, refer to the following:
- Water Spots/Mineral Deposits: As mentioned in the Maintenance section, these can be addressed by wiping the sink dry after use or using a vinegar solution/specialized cleaner.
- Scratches/Chips: While highly resistant, extreme impact can cause damage. Minor scuff marks can often be buffed out with a non-abrasive cleaner. For significant damage, contact BLANCO customer support.
- Drainage Issues: Ensure the drain assembly is clear of debris. The lift and turn drain type allows for easy removal of collected particles.
