Maintenance Tips

• Rinse & Dry Daily: After each use, rinse with warm water and wipe dry with a microfiber cloth to prevent water spots and mineral buildup.
• Use Mild Cleaners Only: Clean with gentle dish soap or non-abrasive cleaners—avoid bleach, ammonia, and harsh chemicals that can damage the composite surface.
• Avoid Abrasive Pads: Do not use steel wool or scouring pads; use soft sponges to preserve the smooth granite finish and color depth.
• Prevent Stains Quickly: Wipe food acids, oils, coffee, and wine immediately—granite composite is stain-resistant but not stain-proof.
• Use Sink Grid (if available): Protects against scratches from heavy cookware and helps maintain a like-new base surface.
• Avoid Standing Water: Do not leave water sitting for long periods to prevent clouding or mineral marks.
• Descale in Hard Water Areas: Occasionally use diluted vinegar or a gentle descaler, then rinse thoroughly.
• Protect from Thermal Shock: Avoid placing extremely hot pots directly from stove/oven into the sink.
