How To Clean Mold Off Grill?

Before diving into the cleaning process, it’s crucial to take some safety precautions. Disconnect the grill from the power source if it’s an electric grill, or shut off the gas supply if you have a gas grill. 

Allow the grill to cool down completely to avoid any burns during the cleaning process.

Materials Required for Grill Cleaning

To efficiently clean the mold off your grill, gather the following materials:

  • Stiff wire brush
  • Dish soap or mild detergent
  • Warm water
  • White vinegar
  • Baking soda
  • Spray bottle
  • Cleaning cloths or sponges
  • Aluminum foil

Step 1: Preparing the Grill for Cleaning

Start by removing the grill grates and any other detachable parts. Soak them in warm, soapy water to loosen the mold and grease. 

While the grates are soaking, carefully inspect the interior of the grill for any visible mold or grime. Use a brush to remove loose debris.

Step 2: Removing Surface Mold

Create a mixture of equal parts white vinegar and water in a spray bottle. Spray this solution over the surface of the grill, focusing on areas with mold growth. 

Let it sit for a few minutes to break down the mold. Then, scrub the surface with a stiff brush to remove the mold effectively.

Step 3: Deep Cleaning the Grill Grates

Remove the grates from the soapy water and scrub them with a wire brush to eliminate any remaining mold or grease. For stubborn mold spots, sprinkle baking soda on the grates and scrub with a brush. Rinse the grates thoroughly with clean water and let them dry.

Step 4: Cleaning the Interior of the Grill

With the grates removed, clean the interior of the grill using warm soapy water and a sponge. Pay close attention to the corners and crevices where mold might be hiding. Rinse off the soap with clean water and let the grill dry.

Step 5: Cleaning the Exterior of the Grill

Wipe down the exterior of the grill with a cloth dampened with soapy water. If your grill has a stainless-steel exterior, use a specialized stainless-steel cleaner for a polished look. Dry the exterior thoroughly to prevent water spots.

Step 6: Maintenance Tips to Prevent Mold Growth

  • After each use, scrape off any food residue and grease from the grates.
  • Cover the grill when not in use to protect it from the elements.
  • Regularly inspect the grill for signs of mold and clean as necessary.
