6. Maintenance and Care
Proper care will ensure the longevity and appearance of your Franke granite sink.
6.1 Daily Cleaning
Clean the sink daily with a mild dish soap and a soft cloth or sponge. Rinse thoroughly with clean water and wipe dry to prevent water spots and mineral buildup.
6.2 Stain Removal
For stubborn stains, use a non-abrasive cleaner specifically designed for granite or composite sinks. Avoid using steel wool, abrasive pads, or harsh chemical cleaners (e.g., bleach, ammonia-based products) as these can damage the surface.
6.3 Heat Resistance
While granite composite is highly heat resistant, it is advisable to use a trivet or hot pad for extremely hot pots and pans to prevent potential thermal shock or discoloration over time.

7. Troubleshooting
This section addresses common issues you might encounter with your kitchen sink.
- Water Spots/Mineral Buildup: Regularly wipe the sink dry after use. For existing buildup, use a solution of white vinegar and water, then rinse thoroughly.
- Slow Drainage: Check the drain for food particles or debris. Use a plunger or a non-corrosive drain cleaner if necessary. Avoid harsh chemical drain cleaners.
- Scratches: While granite composite is scratch-resistant, heavy impact or sharp objects can cause marks. Minor surface marks may sometimes be buffed out with specialized granite polish.
- Discoloration: Ensure proper cleaning and avoid leaving highly pigmented foods or liquids in the sink for extended periods.
