Operating Instructions

Integrated Ledge Functionality:
The integrated ledge allows for the use of custom-fit accessories (sold separately), such as cutting boards, roll-up drying racks, or colanders.

Maintenance and Care
To ensure the longevity and pristine appearance of your Franke Peak granite sink, follow these simple maintenance guidelines:
- Daily Cleaning: Wipe the sink with a dry, soft cloth after each use to prevent water spots and mineral buildup.
- Stain Removal: For stubborn stains, use a mild soap and water solution with a non-abrasive sponge or cloth. Rinse thoroughly and dry.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, steel wool, or harsh chemical solutions (e.g., bleach, strong acids, or alkalis) as these can damage the granite composite material.
- Heat Resistance: While the sink is heat resistant, it is advisable to avoid placing extremely hot items directly on the surface for extended periods. Use a trivet or hot pad for very hot cookware.
- Scratch Resistance: The granite composite is highly scratch-resistant, but avoid dragging sharp or heavy objects across the surface to maintain its finish.
Troubleshooting
While the Franke Peak sink is designed for durability and ease of use, minor issues may occasionally arise. This section provides general guidance for common concerns.
Water Spots or Mineral Buildup:
- Cause: Hard water deposits.
- Solution: Regularly wipe the sink dry after use. For existing buildup, use a solution of equal parts white vinegar and water. Apply, let sit for a few minutes, then scrub gently and rinse thoroughly.
Accessories Not Fitting Properly:
- Cause: Incompatible accessories or manufacturing variations.
- Solution: Ensure you are using genuine Franke accessories designed specifically for the Peak series. If issues persist with genuine accessories, contact Franke customer support.
