To properly maintain a granite composite sink for longevity, consider the following practices:
- Regular Cleaning: Use a mild dish soap and a soft cloth to clean the sink regularly, avoiding abrasive cleaners that can scratch the surface.
- Avoid Harsh Chemicals: Steer clear of bleach, ammonia, or any acidic cleaners, as they can damage the finish and integrity of the sink.
- Use a Cutting Board: Always use a cutting board when preparing food to prevent scratches and chips on the sink’s surface.
- Rinse Immediately: Rinse the sink immediately after use to prevent stains from food particles or hard water deposits.
- Sealant Application: Apply a granite-specific sealant periodically to maintain the sink’s protective layer and enhance its resistance to stains.
Regular cleaning is essential to keep the sink looking its best. A gentle dish soap combined with a soft cloth will effectively remove dirt and grime without causing damage. Avoid using stainless steel scrubbers or scouring pads, as these can leave scratches on the granite composite surface.
Harsh chemicals can compromise the sink’s finish and lead to discoloration over time.

Rinsing the sink immediately after use is a proactive measure to avoid stains. Food particles, especially those from highly pigmented items like beets or berries, can leave marks if allowed to sit. Regular rinsing will help keep the sink clean and free of buildup.
Applying a granite-specific sealant enhances the sink’s resistance to stains and spills. This should be done every few months, depending on usage, and can create a barrier that prevents moisture and bacteria from penetrating the surface.
