4. Maintenance and Care
Your BLANCO SILGRANIT sink is a high-quality synthetic stone that is inherently easy to care for, scratch-resistant, durable, and heat-resistant. Following these simple care instructions will help maintain its pristine condition:
- Daily Cleaning: After each use, wipe the sink with a dry cloth to prevent water spots and mineral buildup.
- General Cleaning: For routine cleaning, use a mild dish soap and a soft sponge or cloth. Rinse thoroughly with water and dry.
- Stain Removal: For tougher stains, a non-abrasive cleaner specifically designed for granite or composite sinks can be used. Always test on an inconspicuous area first. Avoid harsh chemicals, abrasive pads, or steel wool, as these can damage the surface.
- Heat Resistance: While the sink is temperature-resistant, it is always recommended to use a trivet or hot pad for extremely hot pots and pans to prevent potential thermal shock or discoloration over time.
- Preventing Scratches: Although scratch-resistant, avoid dragging heavy or sharp objects across the sink surface.
