How to Clean Rusty Grill Grates

Grill grates are very exposed to corrosion which is why it is better to know how to get rid of it once it does appear.

For that purpose, I have prepared several methods that you can use to remove rust.

Of course, it is the best to prevent rust from appearing on grates through proper maintenance, but once it does appear, remove it using one of the below methods.

You have natural methods at your disposal as well as those that require toxic agents.

The best solution is to pick non-toxic methods. Trust me, you don’t want to cook food on grates that were cleaned using heavily toxic substances.

Of course, what method you use largely depends on the degree of your rust.

If the rust is shallow and there isn’t much of it, then you can easily get rid of it using natural methods. If the rust is deep, though, you’re going to need special agents to handle the problem.

How to Clean Rusty Grill Grates

Below you’ll find several different other methods of cleaning rusty grates that you can use.

  • Vinegar and Salt – These are environment-friendly products, are edible and make a good combo in rust removal. Mix a cup of salt and two glasses of vinegar in a small vessel. Then put the grates in a durable sack ( a garbage bag will be good ) and pour the vinegar and salt mix inside. Put the bag with grates somewhere on a flat surface for the whole night. Next day remove the grates from the bag and scrub them with warm water using a soft cloth or a sponge. Finally, rinse it with warm water, dry it thoroughly and preserve with oil.
  • Vinegar and Baking Soda – Another environment-friendly way to clean grill grates. Pour baking soda into a container, then gradually add wine vinegar until a consistent cream is formed. Then use a sponge to apply the mix on the grates and wait for at least 30 minutes. After that time, take a soft brush ( preferably with nice bristle ) and clean the grates from rust. Now all you have to do is clean the grates from leftover dirt using water, dry it, and then preserve it.
  • Water and Soap – Use warm water and a soft grill cleaners ( soap ) to clean the first tiny signs of rust. If the rust has just started gently appearing, that’s the easiest way to get rid of it. Then of course dry the grates thoroughly and preserve with oil.
  • Wire Grill Brush - You can use this method if the rust appeared to a small degree. Just use a wire grill brush to scrub the rust. It will be the most convenient to place the grates on something like concrete floor and scrub the rust off the surface. Help yourself by cleaning rust remains with an old, soft cloth. This method has one significant downside, it causes big scratches on the surface of the grates. That’s why you should preserve the grates with oil right after you’re done cleaning. Another downside is the fact that a brush won’t clean perfectly in all spots.
  • Commercial Rust Remover - It’s a solution for much more serious signs of rust on your grates. Most of these types of agents are made of substances that are toxic. That’s why when you’re at the store, you should ask for a professional product dedicated to grill grates. How to use it? There are plenty of products so I can’t give a clear-cut answer to this question. It is the best to read the instructions that the product will surely come with.Don’t forget to preserve it again after you’re done cleaning.

Remember ! After each thorough cleaning of grates that were covered with rust, you have to preserve your grates one more time in order to effectively protect them from rust appearing again.
