Steps to Clean Blackstone Griddle Rust 

Now it’s time to clean your griddle.

Step-1: Make a Clean Sweep.

First, make sure you’re wearing heat-resistant gloves so you don’t get burned. Just in case, turn off the Blackstone griddle. Before removing the rust, make sure that the griddle surface is clean enough to expose the rust.

Step-2: Prepare the Griddle for Cleaning.

Turn the Blackstone griddle to the maximum heat setting and wait 30 minutes for it to get fully hot. The heat will help dislodge the existing rust that has formed on the griddle’s surface.

Afterwards, turn off the griddle and let it cool. Although the rust will not harden so quickly, start clearing it up as soon as possible.

Step 3: Remove the Rust.

Take your metal scraper and start removing the rust on the griddle while the rust is still soft and not adhering to it. The rust will simply come off the griddle.

Depending on the width of your metal scraper, you may pick up the rust with the scraper and dispose of it in a trash bag or waste bin. Repeat this process until the griddle surface feels smooth when rubbed with a scraper.

Step 4: Scrub the Blackstone griddle with oil.

Pour a few spoonfuls of the cooking oil of your choice onto the griddle. The amount of cooking oil you pour on the griddle depends on your griddle’s surface area. 

Make sure you apply the thin film of oil. It’s also good to add some lemon juice, citrus juice or vinegar to the oil.

Scrub the griddle with your grill stone or sandpaper now. The scrubbing motion should be mild and circular, so you don’t miss any scrubbing directions and don’t damage the griddle’s metal. You must continue scrubbing until the griddle appears bright and smooth.

Wipe away the rust and oil’s black liquid. You may do this using rags or paper towels. After removing the residue, reapply the oil and scrape until the oil looks cleaner when wiped off.

Wipe up all the oil on the griddle with a sponge dipped in vinegar and warm water. This will remove any rust odors from the griddle while also cleaning it. 

If the rust hardens before you scrape it completely off, you may reheat the griddle for a few minutes to activate and soften the rust.

Step 5: Season the griddle.

After you have cleaned your Blackstone griddle and it appears rust-free, season it as the last step. Seasoning your griddle protects it as the oil itself acts as a protective coating, preventing further corrosion. 

Cleaning your griddle is still necessary at least once a month. However, seasoning it with a thin layer of oil on top after using it makes the rust form much more slowly.

For the seasoning, use some cooking oil with a high smoke rate like flaxseed oil or olive oil is the best cooking oil. These oils adhere to metal or bond with metal significantly more rapidly and effectively.

  • Apply the first coat of oil on the griddle surface and spread it with the help of a paper towel. Now turn the flame high and let the griddle heat for 15-20 minutes until the oil smokes and you see a shiny surface with no oil. Turn the flame off and let your griddle cool.
  • Apply a second oil coat once the first one dries for further protection. The thicker the protective layer, the more difficult it is for water or air to access the griddle’s iron surface. As a result, rust will be less likely to develop.
  • Repeat the process for the third time.

How can you Remove Stubborn Rust to Restore Blackstone Griddle?

If the rust on the griddle has been sitting for a long time, cleaning it with baking soda, citric acid, and other substances might not get the job done. In such cases, it is preferable to remove it by rusting with tools that help you with grinding, scraping, and sanding the rust off the metal.

Grinde the Rust

Grinding is the most powerful abrasive that you can use on metals. Therefore, be careful when using an angle grinder on a rusty object, as it might harm the metal under the rust. Instead, use the grinder to remove the heaviest buildup of rust as rapidly as possible.

An angle grinder and its attachments are easily available at a local hardware store or online from sites such as

It’s also worth noticing that the angle grinder can be used for smaller, more detailed regions of your grill. The reason is, they’re small and can get into many nooks and crannies, allowing you to clean particular areas in your grill with accuracy.

After grinding away the rust, use a dish soap solution to clean up the griddle and clean it up using a paper towel or a dry cloth. After that, the griddle can be seasoned using a layer of oil for it to be ready to use. 

Sand the Rust

Sanding is less aggressive than grinding, and it is recommended to use a sander to remove rust when the surface you are cleaning is a large flat surface. 

To remove surface rust fast, inexpensive, and easily, use an orbital sander with hook and loop sanding discs. Sanders are classified according to their coarseness, which is measured in grit.

When using a sander, start with the coarsest grit possible (60 or 80 grit is a good starting point). The reason is, the coarse grits will remove the rust and oxidation efficiently.

You should also work your way up to a higher grit until you have a very smooth, clean-looking surface that you are happy with. You may go up to 400 grit if you want an exceptionally smooth surface.

NOTE: After removing the rust using the mentioned tools, follow the process of cleaning the griddle with a paper towel, cleaning it with oil, and reasoning it.
