How to Clean Commercial Grills & Ovens

One of the most dreaded tasks at the end of any commercial chef's day is cleaning the grills and ovens. If you have several, you can clean them in sequence to save yourself some time, completing one step on each and then going down the row like an assembly line. That way you only have to make one batch of each cleaning solution and will have all of your tools at the ready when you need them.

  1. Put on your rubber gloves. Fill your industrial sink with hot water, as hot as it goes. Add in 1 cup of liquid dish soap and stir to make as much of a lather as you can. Then remove all of the racks from the ovens and the grills and leave them to soak for 15 to 20 minutes. Shake them over the trash can if you can before dropping them in the water to get the large debris out of the way. Throw the drip guards from the grills in the sink, too. If you don't have room, fill a second sink.

  2. Clean the insides of the ovens and grills while the racks soak. Wipe out the inside of each oven with paper towels to remove surface grease. Scrape the top, sides and bottom of the inside of each grill with a metal spatula to remove the carbon grit.

  3. Wipe the ovens out again with a paper towel soaked in ammonia. Let it set for 30 minutes. Use a grill brush to remove any remaining particles from the inside of each grill. Then wipe them out with a paper towel soaked in lukewarm water only.

  4. Use steel wool to scrub the drip guards and racks. Make sure you get all of the food and debris off of them. Then rinse them with cold water from the sink's sprayer hose.

  5. Spray a paper towel with 1 tsp. of kitchen sanitizing spray. Use it to wipe down the inside and outside of the grill and oven doors, the knobs and the handles.

  6. Put the racks back in the ovens and turn them on at 200 degrees for 10 minutes. This will both dry the racks and get rid of the ammonia odor. Dry the grill racks with paper towels or put them in an industrial dishwasher on the dry cycle only.


  • Make sure the gas is off. Let the grills and ovens cool for 30 minutes before you start cleaning so you don't burn yourself.
