How to Clean Cast Iron Stove Grates?

Cooking food is a sensitive issue when you are a health-conscious person. You don’t want it in an unclean way or a dirty place. But if you don’t clean the grates regularly, you’ll see both in your kitchen as a result of daily cooking residues, oils, and debris. Avoiding or delaying it only makes your stove’s efficiency and effectiveness worse. Here are five tips on how to clean cast iron stove grates properly, which will make your stove cast iron grate look new.

There are a few things you need to keep in mind before you start cleaning cast-iron grates. Cast iron can be worn down if you want to clean with the wrong materials, so use scratch-free scrubbers or sponges. Wear gloves before using materials that contain any harsh chemicals. Also, make sure the cast iron grates are completely dry before you return them to the stove.

1. Use Ammonia

The use of ammonia is one of the most popular methods. It’s great for cleaning your grates in a matter of hours. You can use it any way you want. You can get excellent results by soaking for 3-4 hours. It helps to break down food and grease that has accumulated over time.

If you want to clean the grates individually, choose a few gallon-sized ziplock bags. And if you want to clean it all together, you need to take a large-sized bag that can seal well. Place the grates in a bag and add 2 cups of ammonia to it. Seal the grates and ammonia together in a bag and tight it.

The grates mustn’t be immersed in ammonia. Clears gaseous fumes, so it’s important to use a large bag. You can leave the bag alone for about 10 to 12 hours or keep it overnight. You’ll get better results. When the fume soak is complete, wash the grates with soap and water. Never mix any other cleaners with ammonia.

 2. Use Degreaser

This method is relatively simple and less time-consuming. First, soak your grates with adequate degreasers. You’ll need to use an adequate degreaser to fully soak the grates throughout the wetting process.

The degrader in your grates should sit for 15 to 30 minutes. During this time keep checking to see if the grates are still wet. If these start to dry, apply more degreaser and let sit for 30 minutes. The degreaser will slowly allow the unwanted parts to rot in the grates.

Then remove all excess dirt with proper scrubbing equipment. Cast iron may not be enough to scrub with steel wool. In that case, you can use a non-corrosive sponge to thoroughly clean the grates.

 3. Use Baking Soda

This is another simple process. First, clean the grates with soap and warm water. This allows the baking soda to work into the hard ingredients below. Then soak some baking soda in water and mix, and make a thick paste.

Now apply this paste to the burners and wait a while. You can put vinegar in for deeper cleaning. In this, a paste will be coated thick enough.

Then coat all the grates with the paste and wait an hour. Now scrub the build-up with a non-corrosive sponge and rinse the grates thoroughly with warm water. If you find a particularly stubborn amount of grease or grime, then repeat this process twice.

4. Use the Vinegar Solution

Vinegar solutions are great if you are looking for a viable alternative to the above methods. Vinegar contains acetic acid which will help you break down the unwanted/ remnants of your stove grate. It’s one of the best household cleaners which is non-toxic and relatively inexpensive.

You’ll need the same amount of vinegar and water to make this mixture. You’ll also need a spray bottle and a sponge to clean. You can use a toothbrush if you want.

First, fill your spray bottle with the vinegar mixture, and spray the stove grates and burners. Coat the grates and let the vinegar sit for 15 minutes as this will help to easily cut off the unwanted part of the grates. Then scrub the grates with a sponge and wash them off. If you get some stubborn food or grease stains, repeat the procedure twice. It’ll look new.

5. Use Dish Soap

This is a very common process. Cut the grease by dipping the grates into the dish soaps with boiling or hot water. This method works great on enamel-coated cast alloy-iron grates.

This method requires liquid dish soap, a pot of boiling water, a scrub pad, and a microfiber cloth. Allow the grates to cool in, place them in an empty pot or sink, and pour boiling water over the grates to loosen any grease and grime and immerse them in the sink.

Now add a few tablespoons of dish soap and let the grates soak for 15 minutes. Scrub the grates with the scrub pad until completely clean, and rinse again in warm water. Then dry and wipe well before resetting.
