Using A Putty Knife

If you happen to have a putty knife, this is actually one of the best ways to clean cast iron grill grates.


  • Get your putty knife and a wire brush.
  • Start scrubbing the grill grates with the wire brush.
  • Use the putty knife to scrape off any stubborn bits of food.
  • Repeat steps two and three until your grill grates are clean.
  • Once you’re finished, season your grill grates with some oil to prevent rusting.

Using A Wire Brush

If you don’t have a putty knife, a wire brush will do the trick.


  • Start by heating up your grill on high heat for about 15 minutes.
  • Then, using a wire brush, scrub the grates until they’re clean.
  • Once you’re finished scrubbing, turn off the grill and let it cool down.
  • Finally, wipe down the grates with a paper towel or a clean cloth.

Using A Ball of Aluminum Foil

If you don’t have a wire brush or a putty knife, a ball of aluminum foil will do the trick.


  • Heat up your grill to high heat.
  • Use tongs to hold the ball of aluminum foil.
  • Rub the foil all over the grate in a back and forth motion.
  • Rinse the grate with warm water and soap.
  • Dry the grate with a clean towel. 
  • Repeat the process if necessary.

You can also use this method to clean the inside of your grill, where the burners are located. Just be careful not to puncture the foil and cause a grease fire.

Using Vinegar

Another way to clean cast iron grill grates is to soak them in vinegar overnight. In the morning, scrub the grates with a wire brush or putty knife and rinse them off well. You may need to repeat this process a few times if the grates are very dirty.

Using Baking Soda

If you don’t have vinegar on hand, you can also clean cast iron grill grates with baking soda. Just make a paste with water and baking soda and scrub it onto the grates. Let it sit for an hour or so before scrubbing it off with a wire brush or putty knife. Rinse the grates well and dry them before using them again.

Prevents Rusting

Cast iron is a very sturdy metal, but it is also susceptible to rust. When moisture and oxygen come into contact with the metal, they cause it to break down and form rust. Rust can weaken the structure of the grill grates and cause them to break. Cleaning your grill regularly will help prevent rust from forming.

Improves Cooking Performance

If your grill grates are covered in grease and dirt, they will not be able to conduct heat as well as they should. This can cause your food to stick to the grates and cook unevenly. Cleaning your grill grates will help them cook more evenly and prevent sticking.

Makes Grill Grates Last Longer

Cleaning your grill grates on a regular basis will help them last longer. Grease and dirt can break down the metal and cause it to deteriorate faster. By keeping your grill grates clean, you can extend their life.
