How to Clean Old Grill Grates    

Methods we are going to discuss may include: 

  • Soaking in boiling water and vinegar
  • Soaking in an abrasive dish soap solution
  • Scrubbing with cleaning pads or sponges
  • Running over with a power washer
  • Banging on them with a wooden spoon or mallet.

The methods we recommend all work, but the one that is proven to work the best is soaking in boiling water and vinegar. This method can be used to clean most types of grills, including some of the older, cast-iron grills. It will also get rid of any food particles or dirt that has been stuck on your grill since its last cleaning.

So let’s discuss it first.

Method 1: Soaking in Hot Water and Vinegar

This method involves pouring two cups of white vinegar into a large pot with two gallons of hot water. Then you add your old grill grates to the pot and let them soak for at least twenty minutes. By the time they’ve soaked for that long, most of the grime should now be gone and your grill should look much cleaner. 

If there’s still some residue or some stubborn stains, you can leave them to soak longer. After soaking, you’ll want to use a scrub brush with soap to get any remaining dirt off of the grates.

Method 2: Soaking in an Abrasive Soap Solution  

If you don’t have any vinegar available, then you can try boiling water and soap instead. First pour four gallons of boiling water into a large pot. Then add two bars of soap into the pot and stir it up really well so it’s all melted into the water. Next, you can add your old grill grates to this pot and let them sit for at least twenty minutes. Afterward, use a scrub brush with soap to get any remaining dirt off of the grates.

Method 3: Scrubbing with a Cleaning Pad or Sponge

If you don’t want to use vinegar or hot water and soap, then you can try cleaning your old grill grates with a cleaning pad or sponge instead. The great thing about this method is that it’s very quick and easy. However, it’s not always as effective as using an abrasive solution like vinegar or a scouring pad.

This method works by applying a cleaning pad or sponge to the grates, then scrubbing them. To help loosen the grime, you can sprinkle a little bit of salt on your cleaning pad or sponge. As you scrub, the salt will help break up the grime so it’s easier to get off. If this method isn’t effective, then all you need to do is rinse your grill grates under warm water and they’ll look just like new again.

Method 4: Using a Power Washer on Your Old Grill Grates

This method is one that many people have tried and it’s proven to work well for them. You can also purchase a power washer to help you clean your old grill grates. However, you’ll need to be very careful when using this method because power washers can damage your grill. 

It’s best to do this on a section of your grill that isn’t attached to the base, or if it is attached, make sure you remove the screws holding it down. But, be careful that you don’t get the water too close to any screws because the water can cause them to loosen. 

To use this method, you’ll want to choose the correct power washer size for your grill. And then pour a little bit of warm soapy water and dish soap onto a sponge or cleaning pad. Then scrub your old grill grates with it until they’re clean and free of any dirt or debris. 

Repeat this process several times until all the grime has been removed. Afterward, rinse them off under warm water to get rid of any soap residue that may have built upon them. Once you’re finished cleaning, you should be left with clean and shiny grill grates.

Method 5: Using a Wooden Spoon or Mallet to Clean Your Grill Grates

This method will work for most types of grills. It involves taking a wooden spoon or mallet and banging on the grill grates. This method is great for getting rid of any stuck food particles that are built upon your grill. After you’ve cleaned up all the food, you should be left with nice, clean grill grates. This may take several tries to get it completely clean, but each time you’ll be getting them a little cleaner than the last time.
