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.
