  Maintenance Tips

  • Clean daily with mild dish soap + soft sponge – Keeps the 18-gauge stainless steel surface smooth, hygienic, and streak-free.
  • Rinse and dry after use – Prevents water spots, limescale buildup, and dulling of the finish.
  • Avoid harsh chemicals & abrasives – No bleach, steel wool, or scouring pads, as they can scratch or damage the protective surface.
  • Wipe in the direction of the grain – Helps maintain the uniform brushed stainless steel appearance.
  • Clean corners and edges regularly – Topmount design can collect residue around the rim; wipe the mounting deck to prevent buildup.
  • Use sink grid protection – Prevents scratches from heavy pots and preserves the deep single-bowl interior.
  • Descale occasionally – Use a diluted vinegar solution or stainless steel cleaner to remove mineral deposits.
  • Flush drain weekly – Run hot water to help keep plumbing and drain channel clear of debri
