Brass, Enamel, and Finishes
La Cornue ranges are finished in enamel and often trimmed in brass, chrome, or nickel. Wipe surfaces with a soft cloth and a mild cleaner, and steer clear of abrasive pads and acidic products that dull or strip the finish. Many ranges use a living or lacquered brass that mellows over time by design, so gentle care preserves the look the maker intended. Wipe spills while the range is cool rather than scrubbing baked-on residue later.
Burners and Igniters
The gas top uses substantial burners with removable caps. Keep the caps and ports clean and dry, since a film from spillovers or moisture is the usual reason a burner clicks without lighting or burns unevenly. Cool the burner, lift the cap, clear the ports gently, dry the igniter, and reseat the cap squarely. Hand-wash the grates rather than putting them through a dishwasher, which can dull their finish.
The Vaulted Oven
La Cornue is known for its vaulted oven, whose curved ceiling circulates heat for even baking. There is no high-heat self-clean cycle, so clean the enamel cavity by hand with a gentle cleaner once it has cooled. Keep the floor and racks clear of spilled debris to prevent smoke and odor. If baking starts to run uneven or off-temperature on an electric oven, that is a signal for a technician to check the element and controls rather than something to adjust yourself.
Altitude and Professional Care
At Vail-area elevation a gas range calibrated for denser low-elevation air can run rich, with a lazy yellow flame and reduced output. On a hand-built range this air adjustment is best left to a technician who knows the burners. Because these ranges are built to last for decades, periodic professional attention to the gas system, the oven controls, and the door mechanisms protects a significant investment. Our altitude guide explains the underlying physics.
Maintenance Schedule
| Task | Interval | Why It Matters |

| Wipe brass and enamel gently | Ongoing | Preserves the finish |
| Clean burner caps and ports | After spills / monthly | Reliable, even flame |
| Hand-clean vaulted oven | As needed | Even baking, no odors |
