Maintenance Tips

• Clean daily with mild soap + soft cloth
  Preserves the satin finish and prevents buildup from everyday kitchen use.
• Dry after each use
  Wipe with microfiber cloth to avoid water spots and keep a streak-free shine—especially important in hard water areas.
• Avoid harsh chemicals & abrasives
  No bleach, steel wool, or abrasive pads—these can scratch or dull the brushed finish.
• Rinse food acids quickly
  Coffee, citrus, vinegar, and salt can cause discoloration if left too long.
• Use the bottom grid
  Protects against scratches and dents from heavy pots and keeps drainage flowing efficiently.
• Clean corners regularly
  Rounded corners are easy to maintain—use a soft brush or sponge to prevent debris buildup.
• Remove mineral deposits weekly if needed
  A diluted vinegar rinse helps eliminate limescale and restores shine.
• Maintain accessories separately
  Wash drain strainers and grids regularly to prevent odor and clogging.
