How to Clean Cast-Iron Cooktop Grates

Cleaning cast iron cooktop grates is an important step in keeping them in tip-top shape, which you'll surely want to do if you want to keep enjoying the benefits these cooktops offer. One of the main benefits of cast iron over porcelain is its durability: cast iron is much more difficult to chip than porcelain-covered grates would be.

In addition, the continuous design of many cast iron stovetop grates adds to their convenience, in that they make it much easier to move pots and pans around your cooking space. As durable as they are, however, cast iron cooktops can become just as dirty as any other part of your cooktop, thanks to baked-on spills and splatters. So if you're looking for some advice on how to make cast iron grates look brand new, you've come to the right place, thanks to our expert tips on how to clean cooktop grates.

Methods For Cleaning Cast-Iron Grates:

Cast Iron
Soapy Water

Try some soapy water

Sometimes all it takes to clean your cast-iron cooktop grates is to treat them like many of your other dishes. To start, simply remove the grates from the cooktop and place them in the sink. Fill the sink with warm water and dish soap, and allow the grates to soak for 10-15 minutes. This will help loosen any cooked-on matter. Then, using a soft brush or sponge, scrub the grates thoroughly to remove any stuck-on residue.

Finally, rinse the grates thoroughly with warm water, dry them with a clean towel, and place them back on the cooktop.


Tackle grime with white vinegar

If soapy water doesn't do the trick, you may want to tackle the job with white vinegar, which is known for its ability to help clean many types of surfaces. To start, combine one part water and one part vinegar in a spray bottle. Spray the mixture liberally onto the grates, and allow it to settle for around 15 minutes.

After the vinegar has had a chance to work its magic on your cast iron grates' surface, simply wipe it away with a clean, damp cloth. You should be left with grates looking much closer to new.

Baking Soda

Put your baking soda to work

Baking soda is another substance known for its remarkable cleaning capability. So it's no surprise that it's also great for cleaning cast iron cooktop grates.

To tackle your cast iron cooktop with baking soda, start by creating a thick paste by combining three parts baking soda with one part water. Coat your grates with the paste using a soft brush or cloth. Double check that you're getting to all the hard-to-reach places. Let the paste sit for up to 20 minutes, allowing it to work its magic by loosening all the stuck-on grease and grime.

After the residue has had a chance to loosen, use a soft brush to remove it before thoroughly rinsing the cooktop with warm water.

All of these methods are great ways to keep your cast-iron cooktop looking as good as new without resorting to harsh chemicals or sprays that could do more harm than good to your grates' surface.
