How to Clean Cast Iron Grill Grates




Different people buy cast iron grill grates for a number of reasons. First, they are very durable. If they are properly maintained, the grates will actually last longer than your grill easily. The grates are also able to retain even heat when you are cooking. This ensures the food is properly cooked. Continuous use of cast iron grates with regular seasoning will also make it nonstick just like the cast iron pan. Despite the durability, cast iron grills are not 100% foolproof. They are prone to rust and if not cleaned and maintained properly, they will become unusable very fast.

Here we will look at basic maintenance tips for cast iron grates including how to clean them. We will also show you a few tips grilling made easy by Raymond-nh on how to keep the grates in good condition for a long time.

Step-by-Step Process

You can keep your grill clean by cleaning it properly every time you use it. It sounds a little obvious but you would be surprised by the number of people who actually don’t do it. Once you have finished grilling and the food is removed from the grate, open up all the vents if you are using a charcoal grill. In case you are using gas, turn up the grill and close the lid.

The aim here is to make sure that the grate gets really hot. This helps to burn off the stuck food. Once this is done, turn off the grill. Let it cool until you can clean it up using your hands. While the grill is warm, scrape off any of the remaining stuck food on the grates by using a grill brush. Clean the bare metal up after that and let it dry. Once the grates are dry, it’s time to put in some anti-rust measures. Applying a thin layer of vegetable oil should work. However, make sure you apply a very thin layer.

It may take a few minutes before all the rust is removed so keep repeating the process until you are done.
