Recommended Ways of Cleaning Cast Iron Stove Grates

To make the process as simple as possible, you can always wipe down your cast iron grates and burner caps with a damp cloth or sponge and dry them completely each time after cooking. This is considered maintenance cleaning and can be done with regular hot, soapy water (mild dish soap) or a mild store-bought cleaner such as Soft Scrub.

If, after cleaning, you notice some spots that did not get removed, you can use an alternative method; however, it requires using newspaper and going outdoors. Just purchase some Easy-Off Fume Free Max Oven Cleaner or a similar product depending on the availability and follow these instructions for using an oven cleaner on your cast iron stove grates:

  • Remove your grates and the burner caps.
  • Go outside and place them on top of some newspapers.
  • Spray with the oven cleaner you chose to use.
  • Allow the cleaner to sit on the stained areas for approximately 1 to 2 hours.
  • Then clean them off with hot, soapy water (mild soap).
  • Now make sure you dry them entirely from top to bottom.

When you are cleaning cast iron stove grates and burner caps, you have to thoroughly dry them underneath. If the bottom of the grates does not get completely dried before putting them back on your stovetop, they could endure some rust.

You can also put the cast iron grates and burner caps on top of your stove burner and turn the burner on maximum for just ten to fifteen seconds to make sure they are completely dry.

Once they are completely dry, we recommend applying vegetable oil to them and allow the oil to soak in for about 15 minutes before returning the cast iron stove grates or burner caps to their location on your stovetop.
