Due to the nature of cast iron stoves, most consumer cleaners, soaps and scrubs are too harsh and not recommended for cleaning them, so a non-abrasive cleanser, grease-fighting dish soap and nylon scrubber are the recommended tools to use, notes TheKitchn.com. Depending on the stove's finish and the amount of built-up dirt and grease, the best option is the mildest option. Homemade cleaning remedies such as rubbing a potato with a kosher salt paste can also clean cast iron without removing the finish.
In addition to using the recommended cleanser, cleaning cast iron stoves is best done when they are completely cool, notes TheKitchn.com. Cleaning cast iron stoves while hot can crack and damage the grates.
- Degrease the grates
- Clean with non-abrasive powder
Remove the grates and place them in a sink. Slowly pour boiling water over the grates to initiate grease removal. Soak the grates in hot, sudsy water, using the dish soap, for about 15 minutes.
If necessary, sprinkle the non-abrasive cleanser onto a nylon scrubber and rub the cast iron until stubborn grease or spots are removed, letting them set for an additional five minutes before rinsing thoroughly with warm water. Immediately dry the grates after desired cleaning results are achieved.
Cast iron wood stoves or cast iron skillets and cookware should be washed of surface dirt and scrubbed with a brush, applying grease to aid in removing tough dirt. If any abrasive cleaners or scrubbers are used, the cast iron may need to be re-seasoned.
