The Secret of How to Clean Cast Iron in Four Easy Steps
How many times have you passed up a rusty cast iron pan at a thrift store or a garage sale thinking that it was ruined and not worth taking home?
At some point, everyone hears the myth that cast iron cannot be cleaned. Not true! Despite the fact that they can’t be washed in the dishwasher and are heavier than most kitchen cookware, a cast iron skillet can outperform and outlast other pans in your kitchen with very minimal care. Although many rusted or burnt cast iron pans are simply discarded; with just a few household ingredients and a little bit of work, cleaning a cast iron pan can easily restore it to its original beauty and function.

Why rescue and clean a cast iron pan that looks like the one above? Aside from the fact that cooking with cast iron produces wonderful tasting food, there are many other benefits! Cast iron retains heat better than any other cooking surface; making it incredibly good at evenly searing food. While most kitchen pans wear out and get replaced after repeated use, cast iron pans actually improve with age and perform better the more they are used! That is the more times a cast iron pan cooks and is seasoned by cooking oils, the better the natural nonstick coating on the pan becomes. A cast iron pan doesn’t have a chemical coating on it like other nonstick cookware found in kitchens, lessening the risk that chemicals find their way into food and allowing for any cooking utensils to be used on it without worry of scratching or damaging the pan.
The minimal effort cleaning cast iron takes pays dividends and caring for cast iron pans is an investment in the future of your cooking. Next time you see a rusty or dirty cast iron pan, be sure to salvage it with these easy steps!
How to Clean Rusty Cast Iron
Follow four simple steps—scrub, rinse, season, bake— and discover the secret to how to clean cast iron using products you probably already have at home.
Step Scrub Rusty Cast Iron
The first step to cleaning cast iron is to remove the rust. One simple and extremely effective way to do this is by cleaning cast iron with salt. Two items found in most homes—a damp cloth and kosher salt— may be all that is necessary to scrub the rust and grime from a cast iron pan that would otherwise be thrown away. Simply dip a damp cloth in kosher salt and carefully rub off the rust from the surface, including the inside edges of the pan.
Step Rinse and Dry the Pan
Although the rust was most likely caused by water left on the surface of the pan, this step is very important to ensure that all of the grime and dust just scrubbed free gets completely removed! Rinse the pan thoroughly under running water until the water runs clear and towel dry it. When most of the moisture is removed, move the pan to the stovetop and heat to completely remove all moisture and begin to open the pores for seasoning. Be cautious now that the pan is hot!
Step Season Pan with Oil
Place a sheet of tinfoil across the bottom rack of the oven and preheat the oven to 350°. Using oven mitts, carefully remove the pan from the stove and, while the pan is still warm, coat the pan with the oil of your choice on both the inside and outside. Vegetable oil, coconut oil, olive oil, or even the flaxseed oil shown below work well. If necessary, use tongs to hold a cloth or paper towel to rub the oil into the pan to avoid the risk of a burn. Seasoning the pan with oil seals the pores of the pan and allows a nonstick coating to build up that will provide the best cooking surface.
Place the oiled pan face down directly on the top oven rack, making sure a tinfoil sheet covers the rack below to catch any oil drips. Bake the pan for one hour. Carefully remove the very hot pan from the oven and admire the restored sheen! The pan should now appear more black than gray. Rub away any excess oil and let the pan cool thoroughly before storing until ready to use.
