Operating Instructions
This kitchen sink is designed for standard kitchen use, including washing dishes, preparing food, and general cleaning tasks. The low divide feature allows for easier maneuvering of larger items such as baking sheets and oversized pots between the two bowls, enhancing versatility.
Ensure proper drainage by keeping the drain clear of large food particles. Basket strainers (sold separately) are recommended to prevent clogs.
Maintenance and Care
To maintain the appearance and longevity of your BLANCO SILGRANIT sink, follow these care guidelines:
- Daily Cleaning: Clean the sink regularly with mild soap and water. Use a soft cloth or sponge.
- Product Care Instructions: Hand wash only. Avoid using abrasive cleaners, steel wool, or harsh chemicals, as these can damage the SILGRANIT surface.
- Stain Removal: For stubborn stains, a diluted solution of bleach or a non-abrasive cleaner specifically designed for granite composite sinks can be used. Always rinse thoroughly after cleaning.
- Heat Resistance: While SILGRANIT is heat resistant, it is advisable to use trivets or hot pads for extremely hot cookware to prevent potential thermal shock or discoloration over time.
- Hygienic+Plus Surface: The non-porous surface naturally resists bacteria and dirt, making it easy to keep clean and hygienic.
Troubleshooting
If you encounter issues with your sink, consider the following common solutions:
- Slow Drainage: Check for obstructions in the drain. Remove any food particles or debris. If the issue persists, the plumbing trap may require cleaning.
- Water Spots: These are common in hard water areas. Wipe the sink dry after each use to minimize mineral buildup. A vinegar solution can help remove existing water spots.
- Discoloration/Stains: Refer to the Maintenance section for stain removal tips. Ensure you are not using harsh chemicals that could cause permanent damage.
