How to clean a Flat Top grill that has rust

If your Flat Top grill has developed some rust, use this simple fix to get it looking like new. Rust only forms on the surface, so scraping it away leaves fresh steel ready to re-season like new.

Follow the steps below to clean a rusty Flat Top grill;

  • Place your Flat Top grill on the stovetop and heat medium-high for 20 minutes. This will loosen the rust from the steel, making it easier to remove.
  • Let the Flat Top grill cool. Then, use a scraper to scrape the entire surface to remove any rust that has formed.
  • Spread 4-5 tablespoons of oil across the surface of the Flat Top grill and scrub it down with a grill stone. If you don’t have a grill stone, use steel wool or medium grit wet-or-dry sandpaper.
  • Wipe the Flat Top grill clean with a cloth or paper towels.
  • Drip another 3-4 tablespoons of oil and wipe the grill down again. Repeat until all signs of rust are gone.
  • Season the Flat Top grill to create a protective coating that avoids rust. Any cooking oil works, but we prefer Flat Top grill Oil or extra virgin olive oil.
  • Then drip another 3-4 tablespoons of cooking oil for an extra protective layer. This blocks contact between air and water with the griddle plate.
  • Keep your grill stored in a cool, dry place, and use a cover to protect it from humidity in the air.

Other natural cleaning methods

Onion Scrubbing:

You can easily clean a flat top grill without any grill brick. First, cut your onion in half. Then rub it on a hot grill for at least five to seven minutes. Once you see the food debris coming off the surface, continue onion scrubbing for about two minutes. Doing this will remove all the food debris and sauces that got hard during baking.

Soda Water and Carbonation:

Carbonation relaxes and eradicates hardened food debris and extra fat. So, pour some club soda on your flat top grill when it’s hot.

Scrub the exterior of your grill with a griddle brick in concentric circles. Remove the loosened dirt from your grill.

Beer Cleaner:

Just pour some beer on the warm grill and scrub it. Then drain the liquid off to get a shiny surface. Wipe it dry using a rag or paper towel.


You can also try coffee as a flat top cleaner to clean your kitchen grill. First, you need to bathe it with coffee to loosen up food debris, dirt, and oil. Then scrape off the food debris with a wire brush and drain the fluid.

Hot Oil Cleaning:

Pour oil on the grill when it’s still hot. Next, scrub the cooking appliance with a griddle brick in a circular motion to mix it with food debris and extra fat. Later wipe the loosened debris and get a clean flat top grill!

How to clean a Flat Top grill with baking soda

Follow the steps below to clean your flat top grill with baking soda.

Items Needed

  • Vinegar
  • Baking soda
  • A large deep dish to mix the ingredients
  • Stirrer
  • Scouring pad
  • And a grill bush in case there is food particles in the corners.

Complete Process of Using Vinegar and Baking Soda Solution

Step 1

To clean a Flat Top grill, ensure your grill is hot at a temperature of 300 degrees F. For this, turn the burners on to the medium setting. When the surface is properly hot, turn the burners off. Doing this will soften all the hard stains and the food particles. It’s an important step that all of our readers must know.

Step 2

Now make the mixture of both the ingredients. For example, take two cups of vinegar and half a cup of baking soda. Mix both of these in a large-sized deep dish.

Here the primary purpose of using a large deep dish is because the soda will bubble up and cover a large area. Stir both the ingredients with the stirrer to make a foamy solution.

Step 3

Take this solution and pour it on the hot grill surface. Better to leave it overnight. But if you can’t wait for so long, leave the solution on the grill for 4 to 5 hours.

Step 4

As time passes, you’ll see the hardened food debris bubbling and becoming soft. Take a scouring pad and scrub the surface to loosen the gunk. When all the food debris gets completely soft and separated, use water to wash away the solution.

Note: Allow the cooking surface to cool down until it is warm before scrubbing it with a soft grill brush or scouring pad. Removing stuck food particles, grease, troublesome fat, and other drippings is much easier when the grill is still warm.

How to clean a Flat Top grill with ice

Place pieces of ice on the grill surface and let them melt, creating steam that will help dislodge debris on the grill.

Can you use vinegar to clean a flat-top grill?

Yes. The vinegar will clean the grill and eliminate any odors from foods with strong odors, such as fish and other types of seafood. The vinegar will also help to create a polished look if you have a stainless steel flat top grill.

Note: Refer to your user manual to see if your manufacturer advises against using acidic agents on your flat top grill.

How often should I clean my Flat Top grill?

You should give it a thorough clean after every use to remove stuck food particles and prevent cross-contamination. However, if your flat top grill is for home use, you don’t have to worry about deep cleaning it daily. Instead, you can schedule it for a thorough cleaning every 4-6 months, depending on how you often use it.

Deep cleaning your flat top grill will entail disassembling the entire appliance and inspecting the burners, exterior, and gas pipe for leakages, cuts, rust, and other issues.

Finally, ensure you cover the grill when not used to protect it from harsh weather conditions and other elements such as dirt, dust, and debris. This is particularly important if you often leave your grill outdoors in the yard.
