You need to ensure that the aluminum foil is large enough to cover most of your grill grates easily without overlapping them. Once you have covered your grill grates, place them in the oven for about 20 minutes at 400 degrees Fahrenheit (200 degrees Celsius).
After this period has elapsed, remove the grill grates from the oven. Let them cool down completely before cleaning them up again using water and some paper towels. It will help you eliminate any leftover oils from the previous cooking process and protect your food from getting burned during this process.

How to Prevent Grills from Rusting
Wash the grills utterly after every use to prevent them from rusting. They should be dried thoroughly to prevent moisture. Oil the grill so that the saltwater does not damage it. Cover a grill and keep it in a garage or dry place. The following are some ways to prevent your grill from rusting:
Store Grill In The Garage
If the grill is not in your use, try to store it in the garage. If you live in heavy rainfall or high humidity area, always keep a protective cover over them. It does not matter from which material the grill is made. If you leave the grill outside for a long time, there will be a risk of rusting.
Invest in a Grill Cover
You will have to invest your grill in a cover if you want to keep your grill outside. Always remember that humidity and moisture can cause rusting. Keep your grill in a custom-sized cover to remain safe from moisture.
You can prevent your grill from rusting by using a cover and placing your grill under favorable conditions. You can purchase the grill cover online or from the market.
Dry The Grill Thoroughly
Always ensure that you have dry the grill completely after washing as the water in the grill causes rusting. Check each corner of the grill and if you see water, then dry it with a towel.
Clean The Grill
Many people recommend using a gentle soap, a sponge, and harmful water for cleaning. After using, clean the grill so that any type of ash or food residue can be removed. Otherwise, they can get stuck with the grill.
Maintain The Grill Grates
You can protect the grill grates by rubbing oil into the grill after use. It is recommended that you rub oil into steel grates. After cleaning, apply a thin coat of oil to the grill so that the food cannot stick to the grill.
Always use a little amount of oil and use a dishrag. Your grill will become safe from both rust and moisture by doing this. Never apply oil to the aerosol cans, as they can explode when exposed to flames.
How Often Should I Clean My Grill Grates?
The answer depends on the built material of the grill. If you have a stainless steel grill with a non-stick surface, you should clean them regularly. Stainless steel is extremely durable when cleaned and cared for but requires proper maintenance.
If you have a charcoal grill or an electric one, you will want to clean them less frequently. Charcoal grills tend to get dirty quickly, so they need a little more care than others.
If you have ceramic or porcelain-coated grates, these can last for years without cleaning. You can simple clean them by wiping with a damp cloth or sponge. The food might stick to them, so you must remove them.
These are some maintenance tips for your grill grates:
- Clean the surface regularly with an outdoor cleaning spray or vinegar-based cleaner.
- Do not allow the food residual to be on them for too long. Ketchup can prevent food from sticking to the grate, so I recommend putting it on the steak before it goes on the grill.
- Use silicone baking mats underneath large items that may fall into the fire pit during cooking (like burgers). The mats help keep items from falling into flames or onto other surfaces.
