After a successful barbecue evening, there is often a less popular job waiting: cleaning the grill grate. Burnt-on food residue and grease can sometimes be hard to remove. With the right methods and household remedies, however, cleaning your grill grate is effortless. Here you will find out how to clean your stainless steel or cast iron grill grate effectively and which household remedies work wonders.
Why Is Cleaning Your Grill Grate Regularly Important?
A clean grill grate not only ensures hygienic grilling, it also extends the life of your grill. Burnt-on residue can spoil the taste of your food and reduce the performance of your grill. To keep your grill grate in good shape for a long time, you should clean it after every barbecue. Thorough care is especially worthwhile with heavy use or very dirty grill grates.
Cleaning also prevents old grease and food residue from causing smoke and unpleasant smells the next time you grill. The sooner you start cleaning after grilling, the easier it will be.
How to Clean a Cast Iron Grill Grate
A cast iron grill grate is particularly robust, but it needs special care to prevent rust.
This is how to clean and care for it properly:
- Burn it off after grilling: After the last use, let the grill grate burn off at high heat to remove food residue. This makes cleaning afterwards much easier.
- Brushing: Use a grill brush with brass bristles, as these will not scratch the sensitive material. Brush the grate thoroughly.
- No water: Avoid cleaning with water, as cast iron rusts quickly. If water is necessary, dry the grate immediately.
- Oiling: After cleaning, rub the grate with an oil-soaked cloth to preserve it and protect it from rust. Cooking oils such as sunflower or rapeseed oil are ideal.
- Stubborn dirt: For heavily burnt-on areas, you can make a paste of baking soda and water. Apply the paste, leave it to work and then brush the grate carefully.
How to Clean a Stainless Steel Grill Grate
Stainless steel grill grates are easier to clean and less prone to rust. At Remundi, we use this high-quality material for our grill accessories. Even so, they need regular care:
- Soaking: Place the grill grate in warm water with washing-up liquid. Leave it to soak for at least 30 minutes to loosen burnt-on residue.
- Scrubbing: Use a stainless steel brush or a scouring sponge to remove dirt. Stubborn spots can be treated with a plastic scraper.
- Household tip: Baking soda and vinegar are an effective combination for removing even stubborn stains. Mix the two into a paste, apply it to the grate and leave it to work.
- Polishing: To keep the shine of your stainless steel grill grate, you can polish it with a dry cloth after cleaning.

Household Remedies for Cleaning Grill Grates
If you want to clean your grill grate without using harsh chemicals, household remedies are the perfect solution. Some tried-and-tested tips:
- Newspaper: Wrap the cooled grill grate in damp newspaper and leave it to soak overnight. The next day, the residue comes off easily.
- Baking soda and vinegar: A mixture of baking soda and vinegar helps loosen burnt-on dirt. Apply the paste to the grate, leave it to work and then rinse it off with warm water.
- Coffee grounds: The scrubbing effect of coffee grounds is ideal for stubborn dirt. Simply apply the damp coffee grounds, rub them in and rinse off.
- Onion: Half an onion is a surprisingly effective cleaning agent. Rub the still-warm grate with the cut side of the onion. The onion juice helps dissolve grease and has an antibacterial effect.
Bonus tip: Household remedies are not only environmentally friendly but also inexpensive. Try out different methods to find out which works best for you and your grill grate.
How to Clean Burnt-On Grill Grates
Burnt-on residue often takes more patience and special methods. Here are some effective tricks:
- Oven cleaner spray: It can work wonders. Spray it onto the cold grill grate, leave it to work and then wipe it off with a damp cloth. Remember to rinse the grate thoroughly before using it again.
- Dishwasher tablets: Dissolve a dishwasher tablet in hot water and place the grate in it. After an hour, burnt-on residue comes off easily.
- Burning off the grill: Heat the grill to its maximum temperature and leave it closed for about 15 minutes. The heat loosens burnt-on residue, which you can then brush off.
- Aluminium foil: A crumpled ball of aluminium foil also makes an excellent cleaning tool. Rub it over the burnt-on areas to remove them.
How to Clean a Very Dirty Grill
If not only the grill grate but the whole grill is very dirty, a thorough clean is worthwhile:
- Rough cleaning: Remove coarse dirt and ash with a grill spatula or a shovel.
- Steam: A steam cleaner helps loosen greasy deposits and stubborn dirt. Steam is also environmentally friendly and effective.
- Vinegar water: Mix water and vinegar in a 1:1 ratio and use it to wipe the inner surfaces of the grill. Then wipe again with clean water.
- Grates and plates: Remove all detachable parts and clean them separately with washing-up liquid or household remedies. After all, you want your high-quality plancha grill to last a long time and keep looking good.
- Grease tray: Don’t forget to empty and clean the grease tray. Burnt-on grease causes unpleasant smells!
Cleaning Your Grill Grate: Prevention Is Better Than Cure
With our grill grate cleaning tips, your next barbecue will be a clean affair. The most important thing is to clean regularly. Ideally, don’t wait until you have a burnt-on grill grate to deal with, but look after it regularly. Cleanliness belongs to grilling just as much as the heat of the fire.
To keep your grill grate clean in the long run, you can prevent and minimise dirt. Place aluminium foil or a grill mat on the grate to protect it. Clean the grate straight after grilling while it is still warm. Store the grate in a dry place and care for it with oil.
