How to Winterize Your Outdoor Kitchen

As the temperatures drop and grilling season winds down, it’s time to get your outdoor kitchen ready for winter. A few simple steps now can protect your investment and make sure everything is ready to go once spring returns. Here’s how to properly winterize your grill, appliances, and stainless-steel components.

Grills and Side Burners

Start by cleaning your grill — inside and out. Remove grates and burner covers, scrub off grease and food debris, and empty the grease tray. Run the burners for 10–15 minutes to burn off residue, then disconnect your propane or natural gas supply.

• Clean the unit, inside and out, to prevent 
• Cover your grill with a high-quality, breathable cover to keep out moisture while preventing mold.
• For built-in units, cap your gas line if possible and protect the knobs from freezing rain or snow.
• For freestanding grills, consider moving them into a covered patio or garage for the winter months.

Refrigerators and Ice Makers

Cold weather and refrigeration don’t mix. Most outdoor refrigeration appliances aren’t designed to run below 40°F.

• Unplug the unit, remove everything inside, and wipe it dry.
• Leave the door propped open slightly to prevent mildew.
• If your model has a drain, clear it and ensure no standing water remains.
• For ice makers, drain the water line completely to prevent freezing and internal damage.

Sinks and Water Lines

Freezing water is one of the biggest threats to an outdoor kitchen.

• Turn off the water supply to your outdoor sink and any connected appliances.
• Open the faucet to drain the remaining water.
• Blow out the line with compressed air if possible.
• Remove the faucet if it’s exposed and store it indoors until spring.

Doors, Drawers, and Storage Components

Stainless steel can withstand the elements, but it still requires some care.

• Clean and dry all surfaces using a non-abrasive stainless steel cleaner or mild soap and water.
  
• Check gaskets and hinges, and tighten any loose hardware.
• Keep the doors and drawers closed to block out leaves, debris, and pests.

By taking a few hours to winterize your outdoor kitchen, you’ll prevent costly repairs and extend the life of every component — from your RCS grill to your refrigerator, and storage doors. Come springtime, you’ll be ready to fire it all back up with minimal effort.
