Winter-Proof Your Outdoor Kitchen

The first frost arrives faster than expected. And if you don't prepare your outdoor kitchen in time, a single winter can cause more damage than five summers.

Frozen water in pipes, moisture under the cover, forgotten grease in the grill: All avoidable if you invest a few hours before the temperatures drop.

When is the right time?

Ideally, winter-proof your outdoor kitchen in October, at the latest before the nights regularly fall below zero degrees. In Switzerland, depending on the location, this can become critical as early as early November.

Plan for half a day. If you're doing it for the first time, it will take a bit longer. From the second year onward, it's routine.

Step 1: Shut off the water and drain the pipes

This is the most important point. Frozen water expands and can destroy pipes, valves, and fittings.

Turn off the main valve for the outdoor water line. Open all faucets at the outdoor kitchen so that any residual water can drain out. If possible, blow through the pipes with compressed air.

Also empty the drain under the sink. Standing water in the siphon freezes and can burst the pipe.

Step 2: Disconnect the gas and check the hoses

Close the gas bottle and disconnect the pressure regulator. Inspect hoses and connections for cracks or porous spots. Rubber becomes brittle over the years, especially after summer UV exposure.

Store the gas bottle upright in a dry, ventilated place. Not in the basement, not in the garage next to the car.

Step 3: Thoroughly clean the grill

What isn't clean in the fall is burned in by spring. Remove all grates, burner covers, and removable parts. Clean the interior with warm soapy water. Completely empty the grease collection tray.

Dry everything thoroughly. Enclosed moisture leads to rust.

If you have a stainless steel grill, rub the surfaces thinly with care oil. This forms a protective layer for the winter.

Step 4: Winterize appliances

Disconnect the refrigerator, ice maker, or other electrical appliances from the power. Clean them thoroughly and leave the doors slightly ajar so air can circulate.

Sensitive appliances not designed for prolonged frost are best stored indoors. Check the manufacturer's specifications, as not every outdoor appliance is frost-proof.

Step 5: Protect surfaces

Wipe all work surfaces, fronts, and handles clean. Stainless steel gets a thin oil layer. Oil wooden surfaces one last time and let them dry thoroughly before covering.

Ceramic and natural stone require less care but benefit from an impregnation that keeps moisture away.

Step 6: Cover properly

A good cover is breathable, water-repellent, and custom-fit. Cheap plastic sheets are the worst thing you can do to your kitchen. They trap moisture and create condensation that causes mold and corrosion.

Invest in a cover specifically made for outdoor kitchens. It should have ventilation on the sides and fit snugly so wind doesn't lift it off.

Step 7: Tidy the surroundings

Remove everything loose: cutting boards, utensils, spices, cushions. Empty the trash can. Clear away decorations that could be damaged by snow and ice.

Check if the drain around the kitchen is functioning. Standing water next to the foundation can cause damage to the surface when it freezes.

What if you still want to grill in winter?

In Switzerland, many people grill even in winter. No problem, as long as the water connections are secured. Use the gas bottle only as needed, close it again after grilling, and cover the kitchen between uses.

If you cook regularly in winter, a roof cover is worthwhile. It not only protects from snow but also makes cooking in cold temperatures much more pleasant.

Printable Checklist

• Shut off water and drain pipes
• Disconnect gas, check hoses
• Completely clean and dry grill
• Disconnect electrical appliances from power
• Clean and protect surfaces
• Put on breathable cover
• Store accessories and loose items
• Check drain and foundation

In spring, it's quick

Those who work cleanly in the fall only need to remove the cover, turn on the water, connect the gas, and get started in spring. The feeling of putting the kitchen back into operation after winter is a small highlight every time.
