Maintenance Tips

• Clean daily with mild soap + soft sponge
  Maintains the satin finish and prevents buildup without damaging the brushed steel surface.
• Dry after use to prevent water spots
  Wipe with a microfiber cloth to avoid mineral stains, especially in hard water areas.
• Avoid harsh chemicals & abrasives
  Do not use bleach, ammonia, or steel wool—these can dull or scratch the finish.
• Rinse acidic or salty residues quickly
  Coffee, citrus, vinegar, and salt can leave marks if left too long.
• Use the protective bottom grid
  Prevents scratches and dents from heavy cookware while improving drainage and airflow.
• Clean corners and edges regularly
  Tight-radius corners are easy to maintain—use a soft brush to prevent debris buildup.
• Remove mineral deposits weekly if needed
  A mild vinegar-water solution helps dissolve limescale and restore shine.
• Maintain soundproofing zones dry
  Keep underside pads dry to preserve NoiseDefend performance and reduce condensation buildup.
