How to Clean a Cast Iron Grill


Cast iron heats quickly, retains heat longer than most metals and is long lasting, which makes it an ideal material for outdoor grills and smokers. Iron is also more susceptible to rusting and corrosion, so extra care must be taken to clean and preserve a cast iron grill. Time spent taking care of the cast iron grill pays dividends in the pleasure of using quality equipment.

Things You'll Need

  • Coarse salt (sea salt, for example)
  • Cooking oil
  • Rags
  • Paper towels
  • Brass, copper or stainless steel grill brush
  • Aluminum foil
  • Dish washing soap
  • Steel wool scouring pads
  • Fire up the grill and close the lid to heat the interior for 10 minutes.

  • Scrape the cooking grates with the grill brush to remove as much grease and burnt food as possible.

  • Allow the grill to cool.

  • Make a paste of equal parts liquid dish washing soap and coarse salt, then scrub the cooking grates with the paste and allow it to sit for half an hour.

  • Rinse the cooking grates and dry with paper towels.

  • Coat the grates in cooking oil on both sides until they glisten.

  • Fire up the grill again and place the cooking grates over the fire, closing the grill to allow the grates to bake for one hour.

  • Re-coat the grates with oil when the grill cools, then apply a light coat of oil to the grill exterior and wipe down with rags. This treatment inhibits rust and keeps your grill looking new..
