How to Clean Gas Stove Top Cast Iron Grates (5 Steps)

You know how hard it is when your gas stove top cast iron grates get full of grease, sticky spills, and burnt food. It feels like no matter how much you clean, the dirt just stays. I used to think scrubbing hard was the only way. But guess what? There is a much easier way. In this article, I will show you how to clean gas stove top cast iron grates without scrubbing hard. It works great, and your grates will look almost new again.

Remove the Grates and Prepare the Cleaning Area

The first thing you need to do is take the cast iron grates off your gas stove. Make sure the stove is turned off and the grates are cool to touch. You don't want to burn your hands. Just gently lift the grates and put them aside on a clean surface like a towel or newspaper. This helps keep your counter from getting messy.

Now, choose a good place to clean. If you have a sink big enough, you can clean the grates there. But if the grates are large and don't fit in the sink, use a bathtub or a big plastic bin. Place a towel or old cloth under the grates so they don't scratch the surface.

Next, remove any loose food or crumbs stuck to the grates. You can use a dry brush or an old toothbrush. Just brush off anything that comes off easily. This makes the cleaning easier later.

Now wear rubber gloves to protect your hands. Cleaning products can be strong, and it's better to be safe.

In case your grates are extra dirty, fill your sink or tub with hot water and add a bit of dish soap. Let the grates soak while you get the next things ready. The hot water and soap help loosen the grease and make it easier to clean later. Let them soak for at least 30 minutes.

Always keep a few things near you before you start cleaning. You will need baking soda, white vinegar, dish soap, a soft brush, a sponge, and maybe a plastic scraper. Having everything nearby will save time and make cleaning less messy.

This first step is about getting everything ready and making sure the cleaning goes smoothly and safely.

  • Turn off the stove before removing grates
  • Let the grates cool completely
  • Use a towel or cloth to protect surfaces
  • Soak in hot soapy water for 30 minutes
  • Wear gloves for safety
  • Keep all cleaning tools nearby

Use Baking Soda to Break Down Grease and Grime

Baking soda is one of the best things you can use to clean cast iron grates. It is gentle but strong. It helps break down grease, oil, and burnt food without damaging the metal. And it is safe and natural too.

First, take your grates out of the soapy water and dry them with a towel. You don't need them to be fully dry, just not soaking wet. Then sprinkle baking soda all over the grates. Make sure to cover all sides and corners. Use your fingers to press the baking soda into the dirty spots. This helps it stick and do a better job.

Now, make a paste with more baking soda and a little water. In a bowl, mix 1/2 cup of baking soda and 3 tablespoons of water. Stir until it looks like thick white paste. If it feels too watery, add more baking soda. If it's too dry, add more water.

Use a brush or an old toothbrush to apply this paste on the grates. Rub it gently over the grease and burnt spots. Don't rush. Let the paste sit on the grates for at least 20 minutes. This resting time is very important. It gives the baking soda time to eat away at the tough stains.

After 20 minutes, scrub gently using your sponge or brush. You'll start to see the dirt coming off. Don't press too hard. If the stains don't come off right away, you can let the paste sit for another 10 to 15 minutes. Then scrub again.

If some areas are still greasy, add a drop of dish soap on the sponge and go over those parts again. Baking soda and dish soap together can clean most stains without much effort.

When the grates look clean, rinse them well with warm water. Make sure no baking soda or soap is left. Dry them completely with a towel.

This method is very easy and it works great. It doesn't damage the grates and it saves your energy too.

  • Baking soda is gentle and safe
  • Makes grease and food easy to remove
  • Use paste for better results
  • Let the paste sit for 20-30 minutes
  • Scrub gently, don’t press hard
  • Rinse well and dry fully

Try White Vinegar for Extra Cleaning Power

White vinegar is another amazing cleaner that works well with baking soda. If your cast iron grates are still not fully clean, vinegar can help remove the last bit of dirt, grease, and even rust. It's also natural and safe to use in your kitchen.

To start, you can spray white vinegar directly on the grates. Make sure the grates are dry before you spray. Use a spray bottle and cover every part of the grates with the vinegar. You'll see it start to bubble if there’s any baking soda left. That's a good sign. It means it’s working.

Let the vinegar sit on the grates for 15 to 20 minutes. During this time, the vinegar will break down any leftover grease or stains. After waiting, use a sponge or brush to scrub lightly. The dirt should come off easily now.

If the grates are still dirty, you can do a deeper soak. Mix equal parts of white vinegar and water in a big container. Put the grates inside the mix and let them soak for 30 minutes. This will help loosen even the toughest stains.

After soaking, take the grates out and scrub again with a soft brush. You'll be surprised how much easier the stains come off now.

When you are done, rinse the grates under warm water to wash off the vinegar. Dry them fully using a clean towel. Vinegar smell will go away as they dry.

You can also make a vinegar spray mix to use weekly. Mix 1 part vinegar and 1 part water in a spray bottle. Spray it on your grates after cooking and wipe it with a cloth. It helps keep them clean without needing deep cleaning all the time.

  • Vinegar removes grease and rust
  • Spray directly on grates
  • Let sit for 15-20 minutes
  • Soak in vinegar-water mix for deep clean
  • Scrub lightly after soaking
  • Rinse well and dry completely

Use Ammonia for Heavy Built-Up Grease

If your grates have thick, sticky, black grease that won't come off, ammonia is a strong cleaner that can help. But it must be used safely. Always work in a well-ventilated space and wear gloves. Never mix ammonia with bleach or other cleaners.

First, find large sealable plastic bags, like 1-gallon ziplock bags. Place one or two grates in each bag. Then, add about 1/4 cup of household ammonia to the bag. Do not soak the grates in the ammonia. Just place the ammonia inside the bag and seal it tight. The fumes from the ammonia will do the job.

Place the sealed bags in a safe spot away from kids and pets. Let them sit overnight—about 8 to 12 hours. You don't need to do anything else while they sit.

In the morning, carefully open the bags. The smell will be strong, so open them outside if possible. Take the grates out and rinse them under warm water. The built-up grease and grime should now wipe off easily with a sponge.

If anything remains, gently scrub with a sponge or brush. But you won't need to use much force. Ammonia makes the grease soft and easy to remove.

Once clean, rinse the grates well to remove all ammonia smell. Then dry them completely.

This method is very useful for older or very dirty grates that haven't been cleaned for months. But only use it when other gentle methods do not work.

  • Use ammonia only in fresh air
  • Seal grates in bags with a small amount of ammonia
  • Let sit overnight for best results
  • Open bags carefully—fumes are strong
  • Rinse and scrub lightly if needed
  • Dry grates fully after cleaning

Dry and Re-season the Grates to Protect Them

Once your cast iron grates are clean, you must dry them completely. This step is very important. If you leave any water, it can cause rust. Use a towel to dry them as much as possible. Then let them sit in a warm place or near the stove for air drying.

To protect your grates and keep them strong, it's good to re-season them. Seasoning means adding a thin layer of oil to stop rust and keep them looking nice.

Take a clean cloth or paper towel and rub a small amount of vegetable oil or canola oil on all parts of the grate. Make sure to cover corners and edges. Don't use too much oil—just a thin layer.

Now, place the grates in your oven at 350°F (180°C) for about 30 minutes. This helps the oil stick to the metal and keeps the grates protected. After 30 minutes, turn off the oven and let the grates cool down inside.

This step makes your grates last longer and helps them stay non-stick too. You don't need to do this after every clean, but once a month is good.

  • Dry grates fully to avoid rust
  • Use thin layer of oil to season
  • Bake grates at 350°F for 30 minutes
  • Let cool inside oven
  • Do monthly for best protection

Keep Your Grates Clean with Easy Daily Tips

Keeping your cast iron grates clean every day makes deep cleaning easier. After cooking, always wipe the grates with a damp cloth. This removes fresh food and grease before it hardens. If you spill something while cooking, clean it right away after the grates cool.

Once a week, spray a vinegar-water mix on the grates and wipe it off. This helps remove grease before it builds up. You can also brush the grates with a soft brush once a week to stop food from sticking.

If you want extra protection, line under the grates with foil or stove covers. This makes it easy to clean the stove top and keeps the bottom part cleaner too.

Also, never use steel wool or sharp tools. These can scratch the grates and remove their coating. Use soft brushes and sponges only.

  • Wipe grates daily with damp cloth
  • Clean spills as soon as grates cool
  • Use vinegar spray weekly
  • Brush off loose dirt each week
  • Avoid steel wool or sharp tools
  • Use stove covers for less mess

Frequently Asked Questions (FAQs)

Is it safe to use ammonia on cast iron grates?

Yes, it is safe if you use it the right way. Ammonia should never touch your skin or be mixed with other cleaners. Use gloves and work in a space with fresh air. The best way is to seal the grates in a bag with a little ammonia and let the fumes work overnight. This softens the grease without scrubbing. Just rinse the grates well after. Ammonia is powerful, so only use it when your grates are very dirty and other cleaners don't work.

Can I clean grates without soaking them?

Yes, you can, especially if they are not very dirty. You can use baking soda paste or vinegar spray directly on the grates without soaking. Just let the cleaner sit for 15-20 minutes before scrubbing. But if the grates have burnt food or thick grease, soaking makes cleaning much easier. Soaking helps loosen dirt so you don't have to scrub too hard. It also saves time in the end.

Do I need to season the grates after cleaning?

Yes, seasoning helps protect the grates from rust and keeps them smooth. When you clean cast iron, you remove some of the oil layer that keeps it protected. To season, rub a small amount of oil on the grates and bake them in the oven for 30 minutes. This makes the grates last longer and prevents food from sticking too much when you cook. Try to do this once a month if you cook often.

Is it okay to use dish soap on cast iron grates?

Yes, it is okay to use dish soap on cast iron grates. Just make sure to rinse it well and dry the grates fully after. Dish soap helps remove grease and food. Some people worry about using soap on cast iron, but it's safe if you re-season the grates afterward. Using dish soap for regular cleaning is fine as long as you don't let the grates stay wet for too long.

Can I use a dishwasher to clean my grates?

No, you should not clean cast iron grates in a dishwasher. Dishwashers use high heat and water, which can make the grates rust. The strong detergent can also damage the protective coating. It's better to clean the grates by hand with baking soda or vinegar and then dry them completely. Always season them with oil after deep cleaning to keep them in good shape. Hand cleaning is safer for cast iron.

Do I need special brushes to clean grates?

You don't need special brushes. A soft brush, old toothbrush, or non-scratch sponge works well. Avoid steel wool or hard brushes because they can scratch the metal or remove the coating. If the stains are very hard, use a plastic scraper. Always go for gentle cleaning tools first. If you take care of your grates every week, you won't need anything too strong to clean them.

Is it okay to leave grates wet after washing?

No, it's not okay. Leaving the grates wet can cause rust. Cast iron needs to be fully dry after cleaning. After rinsing, use a towel to dry them. Then let them sit in a warm place or even put them in a warm oven for a few minutes. Drying them fully is the best way to protect them and keep them looking new. Always finish with a thin layer of oil if you deep clean.

Can I use foil under the grates to keep stove clean?

Yes, using foil or stove covers under the grates is a good idea. It catches spills and food, so your stove top stays cleaner. Just make sure the foil doesn't block any vents or gas holes. You can cut small holes in the foil to match your stove's shape. Change the foil every week or when it gets dirty. It saves time and keeps your stove looking nice.
