Cast Iron Grill Grates: How to Remove Rust!!

This may seem self-evident, but it cannot be oversimplified: Cleaning your grill right after each use is the perfect way to keep it clean and free from corrosion. When you’ve done cooking and extracted your food, unlock all vents unless you’re using charcoal, or turn the heat up on your gas grill to high if you’re using gas, and close the lid to allow the grill to heat up.

You’ll be able to cook off a lot of the trapped food and cajun seasoning this way. You can either shut your vents to discharge your charcoal (which can be repurposed) or turn off your gas to enable the grill to chill to the point that you can bring your hand in to clean it after your food has been burnt off. Scrape the grates with a good grill brush while the grill is still hot.

A brush with a scraper is ideal for this because it allows you to quickly remove any leftover food off your grates. After washing and drying your cast iron grates, add a very light coating of olive oil to help stop rust from developing. It just takes a quick wipe with a fabric or kitchen towel gently dipped in oil. You ought to add a thin layer to your grates rather than a thick coating.

How to Clean Cast Iron Grates of Rust?

Mishaps or accidental negligence can cause your grates to rust, which is unfortunate. This will happen if you forget to shield the grill or if you not using it for an extended period of time, allowing moisture to enter the grill. Don’t worry if this occurs; there are many methods for removing rust and restoring your cast iron grates to their glory days.

Soapy Water and Steel Wool:

I believe I should start by stating that you should not wash your cast iron with soap and water unless you want to remove the coating and re-season it. We see just how Lodge Manufacturing, one of largest kitchenware companies in the United States and one of the biggest cast iron pots and pans producers in the world, offers advice about how to clean rusted cast iron.

Grates should be treated with the same caution. Carry the barbecue grates into the place as long as your partner agrees, and clean them in the tub with warm soapy water and iron wool or a strong brush. This will not only strip any coating you’ve accumulated on your grate, but it will also remove any surface corrosion, restoring it to bare metal.

After cleaning your grates, giving them a good rinse before thoroughly drying them. You don’t want the moisture to remain because it can allow rust to reappear very soon, maybe immediately. The easiest way to dry them is to place them in a very low oven for a few minutes to ensure that no water remains in the pores.

Soak in vinegar:

If your drain is deep enough, you can easily soak your grill grates in vinegar to eliminate any rust. Start by soaking the grates in a 50/50 solution of water and distilled white vinegar for about one hour. Then, using a kitchen scrubber or a wire mat, softly scrub away the residual rust. When you’ve done scrubbing, wash the area with soapy water to remove any residual vinegar, then dry completely in an oven at low temperature. 

High Temperature on the Grill/Self-Cleaning Oven:

If your grill has a lot of corrosion, you can need to do more than just scrub it with shampoo and steel wool or cover it in vinegar to remove it. Running cast iron into the oven’s self-clean loop is a tried-and-true method for cleaning cast iron. If you’re not using a self-cleaning oven, you can achieve the same results by placing your barbecue grates in a very hot oven at 600 degree for an hour. Once the grates have chilled (either within the oven or on the grill), give them a simple clean with warm soapy water to eliminate any charcoal that might have accumulated.

Using oven cleaner:

If you have a lot of rust and/or baked-on nastiness on your grill and don’t think either of the other approaches would work, oven cleaner is the only way to get all of your cast iron down to bare metal. Lye, a solid alkaline solvent used for rinsing and drying, is found in just about all oven cleaners.

Before starting the process, you need to have oven cleaner, garbage bag, a large box in which you can store your grills for couple of days and safety glasses and gloves. Spray an even coating on your grates in a properly ventilated environment, then put these inside garbage bags and close the bags tightly sealed. Place them in a warm place where neither children or pets will get to them for a couple of days. Wash the cast iron and give it a good wash in soap and water until the gunk has decomposed. 

Using salt paste:

Create a deep paste of kosher salt and water if you need anything more abrasive than baking soda or vinegar to strip the rust from your cast iron barbecue. Apply it to the rusted patch, then clean it away with steel wool or a wire brush. As required, repeat the process. If you have especially stubborn rust, you will need to start with a salt paste, but after the first few layers of rust have been stripped, you will be able to turn to the less abrasive baking soda paste.

Tips for cast iron grill grates:

Do you want to see how to scrub a grill? You will prolong the life of your grill and enjoy tasty meals served in the great outdoors for many years by taking good care of it. The excellent thing is that keeping your grill in good working order is not complicated. If you follow these guidelines, you’ll be well on your way to developing the practice of grill care.

  • It’s critical to clean the grill grate every time you cook on it, regardless of the kind of grill you’re using. After each use, start taking care of this job. Remove any debris from the grate with a hard wire brush crafted for grill cleaning whilst it’s still slightly sticky. It would be even more hard to wash the grill properly if you wait for it to cool, so do it now.
  • If the grill does have a cast iron grate, you’ll have to take particular precautions to prevent rust from forming. Apply a bit of oil to a clean cloth and spread it on the grate after washing it and allow to cool properly.

After cleaning your grates, make sure to season them.

Whatever method you used to wash your cast iron grates; you should still season them before storing them. Flavouring is essentially the process of baking fatty or oil onto the holes of cast iron at a high temperature that it hydrolyses, creating a durable coating that avoids corrosion and develops a non – stick appearance over period.

One coat would suffice if your grill is hot and you’ve just washed your grates with a grill cleaner, and if you’ve just finished one of the more detailed cleaning mentioned methods above, you’ll would like to add two coats. You can season your grates with cooking oil, but I’ve been using Crisbee to season all of my cast iron recently.

It’s created of bee’s wax, soybean oil, and palm oil and is crafted especially for seasoning cast iron. Crisbee has been my go-to pan cleaner for the past 6 months, and my pans never have looked great!
