4. Maintenance and Care
To maintain the appearance and longevity of your BLANCO Precis SILGRANIT sink, follow these care instructions:
- Daily Cleaning: For routine cleaning, use a soft cloth or sponge with mild dish soap and warm water. Rinse thoroughly after cleaning.
- Stain Removal: For tougher stains, a non-abrasive cleaner specifically designed for granite composite sinks can be used. Avoid harsh chemicals, abrasive pads, or steel wool, as these can damage the surface.
- Heat Resistance: While SILGRANIT is highly heat resistant, it is 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. Consider using a sink grid (optional accessory, item #236593) to protect the bottom of the basin.
- Water Spots: To minimize water spots, especially in hard water areas, wipe the sink dry after each use.
Product Care Instructions:
Hand Wash recommended for cleaning the sink. Refer to the BLANCO website for specific cleaning product recommendations.
