When cleaning the grates after use, it’s important to allow them to cool down until it’s fairly warm in order to keep your hands safe. The first step is to remove the visible grease and food particles, and this is made simple with a grill brush. Most of them are designed with a scrapper on one end and a brush on the other, making it useful for both softer and stubborn stains.

With the brush, it also easier to clean the sides of the grates, which most people often tend to overlook. Please note that if you’re dealing with grates that had been previously stored before cleaning, you might need to warm up the grates a little bit, so that peeling off the accumulated layers of dirt becomes simpler. In the event that it was cleaned prior to storage and you only need a quick fix before you start grilling, a home-made sanitizer will come in handy.

For this you’ll spray the grates with a solution of water and either lemon juice or apple cider vinegar, then wipe off everything with dry paper towels or rag. And after oiling the grates, you can get the cooking started.

By now you understand that water happens to be the greatest hazard to these grill grates. But this shouldn’t get you worried because you can cover your grill from rust by adding some bits of vinegar to your soapy water. Depending on how greasy the grates are, you can soak the whole of it or just use a soaked rag to wipe the remaining layers that couldn’t be brushed off.

Once soft, use a sponge or mild scouring pad to scrub the grates thoroughly until perfectly clean. Talking of mild, you should always use mild soap when cleaning, an example being a dishwashing liquid soap. However, if you have a grill spray cleaner with you, that would do fine instead of soapy water. These cleaners could be costlier compared to regular soap, but the good thing is that they cure the iron and also make cleaning effortless.

Leave them out to dry

Your cast iron grill grates will probably start rusting if you keep them or start cooking with them when still wet. You can choose to air them out in the sun if you want to go the natural way and also have enough time. On the other hand, if you need it prepped-up for the next meal, you can simply use dry paper towels, a rag or even a drier to get it fixed in no time. However, when you use paper towels, ensure that there are no pieces of paper sticking on the grates afterwards.

Season the grates

The best way to improve on the durability of cast iron and prevent rusting is by seasoning it after cleaning and before grilling. Apart from using vinegar, another option is using olive oil or any other cooking oil. To coat the grates evenly, apply the oil using a brush or a clean kitchen towel until every part of the grates is generously coated.

Heat the seasoned grates

Now for other types of grates, we would have stopped at the previous step, but with cast iron, there’s more to that. Coating only has the outermost layer protected, but you need the oil to infuse properly into the iron, and that’s where the heating comes in.  When you realise that the oil coating isn’t enough upon heating, you can add another layer and repeat the heating process until you end up with a shiny and new look. At this point, you can proceed to keep the grill, or start grilling.
