Cleaning your grill grates will help reduce rust buildup and ensure tasty food when you grill. You want to scrape your grates after each use, but you should also do a deep cleanse at least once a year.
Deep Cleaning Cast Iron Grill Grates
We highly recommend that you give your grates a nice hard wash with mild soap at least once per year. Many pitmasters preach that water will surely ruin your grates altogether, however as long as you dry them thoroughly and keep them seasoned, your grates will be fine.
"The good rule of thumb is for every five to seven cooks, clean your grill," says Kevin Kolman, head grill mater for Weber. You should clean the grates of your grill immediately after every use, while the grill is still hot. Protect your hands by wearing gloves when you clean your grill.
No! With that said, you don't want to cook on any surface or use any utensils that are currently rusty. According to the United States Department of Agriculture (USDA), ingesting rust is not safe. In fact, the USDA warns against cooking with rusty utensils and discarding all food stored in rusted cans.
Use a soft-bristled brush or a nylon non-scratch scrub sponge to scour the grates to remove stuck-on food and buildup from cooking. Avoid using abrasive cleaning agents and metal scouring pads, which can damage the cast iron.
Yes, you can absolutely use soap on cast iron. But before you go squeezing out a deluge of Dawn, you should know a few things about using soap on cast iron.
Using a paper towel or brush, brush the grill grates with cooking oil. We recommend vegetable oil, grapeseed oil, or bacon fat. After the grates are coated, you can place them in a 400-degree oven for an hour or on a 400-degree grill for 40 minutes. After time is up, let the grates cool down naturally.
Cast iron retains heat very well making it ideal for grilling, but they do need to be maintained. All cast iron is prone to rust and the best way to alleviate that is to keep your grates and griddle clean and well “seasoned”. Seasoning is just oil baked onto cast iron through a process called polymerization.
Applying vinegar to rust dissolves the oxide and leaves behind a water-soluble salt that you can remove easily. It is called neutralisation, and this reaction happens between rust and acetic acid, which is why cleaning vinegar helps remove iron oxides from household surfaces and objects.
But even if your griddle gets rusty, it doesn't mean you have to toss it. To remove rust, put on a pair of heat-resistant silicone gloves and turn on the griddle to high heat. Scrape off the corrosion using a metal scraper, turn off the heat, and let the surface cool.
Brush the grates: Use a nylon brush to scrape off any food particles or debris that are stuck to the grates. This should also be done while the grates are still hot, as it will be easier to remove any residue before it hardens.
Due to the high heat they are exposed to, and the properties of stainless steel, they may take on a yellowish cast. Some grates will turn darker colors, such as brown or black, as debris from cooking builds up on them.
The wider, flat side of the cooking grates should be facing upwards for cast iron grates. The underside is more pointed like the top of a triangle. There are four small legs in each corner on the underside of the grate to ensure a level cooking surface. This will help stabilize the food.
We suggest that you re-season your grids every four months, or once at the beginning and once at the end of grilling season. This will maintain the finish on your cast iron cooking grids and prevent corrosion.
Coca‑Cola can help clean rust or corrosion, because it contains phosphoric acid, an edible food acid found in lots of foods and drinks. Any acidic drink like orange juice, lemon juice and champagne has the same effect as Coca‑Cola on metal.
Most people know WD-40 Multi-Use Product as a lubricant, but it was originally used as an anti-corrosive by the aerospace industry to prevent spacecraft from rusting. WD-40 can help remove rust from metals like iron, chrome, and stainless steel without further damaging the surface of the metal or removing the paint.
White vinegar, also known as distilled vinegar or spirit vinegar, is made by fermenting grain alcohol (ethanol) which then turns into acetic acid. Water is then added to the vinegar, so white vinegar is made of five to ten percent acetic acid and ninety to ninety-five percent water.

When selecting a seasoning oil, you want one that's high in polyunsaturated fats and has a high ratio of polyunsaturated fat to monounsaturated fat. Among common cooking oils, grapeseed oil and sunflower oil stand out for their high polyunsaturated fat content and desirable ratio of polyunsaturated to saturated fat.
