Mix equal parts water and distilled white vinegar and add it to a container that will fit your rusty cast-iron skillet, such as a bucket or a deep foil pan. Make sure the entire pan is submerged in the mixture, handle included.
The easiest way to remove rust from cast iron is to soak the pan in a 1:1 vinegar and water solution. Then scrub the rust off with a scrubby sponge, scrub brush, or steel wool.
Another way to remove rust from any metallic surface, not just a cast-iron stovetop, is to use WD-40. WD-40 Multi-Use Product protects items against rust and removes rust from them. Simply soak your cast iron stovetop for a short period of time and then scrub it with a wire brush.
No, CLR cannot be used on cast iron; the acids in CLR will react with the metal.
Can I clean cast iron with CLR? We do not recommend using CLR on cast iron. CLR can compromise the metal.
The vinegar solution will dissolve the rust, but once that's gone, it can penetrate further and start eating away at the original cast surface of the pan, the ultimate death sentence for your skillet.
Scrub off stuck-on bits: To remove stuck-on food, scrub the pan with a paste of coarse kosher salt and water. Then rinse or wipe with a paper towel. Stubborn food residue may also be loosened by boiling water in the pan. Dry the skillet: Thoroughly towel dry the skillet or dry it on the stove over low heat.
Mix together equal parts basic white vinegar and water, and either add the solution to the pan if it's rusty only on the inside or completely submerge the pan in a bucket of the stuff to dissolve the rust all over. Letting it soak for about an hour should do the trick, depending on the damage.
Make a paste of six tablespoons baking soda and three tablespoons of water. Scrub down the pan with steel wool. Add vinegar and scrub some more to get rid of all the rust. Rinse with warm water, then wipe down completely.
Can I use steel wool or a metal scrubber to clean my cast iron pan? No! We recommend using a pan scraper or the Lodge Chainmail Scrubber to remove any stuck-on residue.
Coca-Cola is carbonated, which allows it to dissolve with metal oxides and break up rust on a variety of metals and alloys. Phosphoric acid also gives it rust-busting power, while citric acid makes it an effective stain remover.
Set your oven to 350 degrees and put some aluminum foil on the bottom rack. Then pop the skillet in, upside down, on the upper rack for about 1 hour. Turn the oven off and leave the pan inside until it's cool. The oil will bake into the pores of the pan, providing a non-stick finish.
Generously sprinkle kosher salt or coarse sea salt into the pan and scrub it with a clean, damp washcloth. For extra stubborn spots, use a plastic pan scraper to work the burned food off the pan.
The vinegar-and-salt mixture needs time to break down the rust. This can take anywhere from one to three days. Check the tool periodically to see if the rust has softened. Once the rust has softened, use a metal brush or steel wool to scrub off the surface.
Tannic acid, oxalic acid, citric acid, and Ethylenediaminetetraacetic acid (EDTA), can all be used as an industrial rust remover.
The maximum amount of time you should leave your cast iron soaking in vinegar is 8 hours. Any longer than this could be detrimental to the long-term health of the cast iron. You should keep checking back on your cast iron as it soaks, though, because the length of time you need it submerged in vinegar will vary.
Allow your rusty items to soak for around ten minutes. Any stubborn rust spots should now be easier to scrub away.
Additional half hour soaks/scrub sessions may be necessary and are OK, but don't leave the piece soaking for longer periods; the acidity can compromise and erode good iron if left too long. Don't spend extra money on apple cider or name brand vinegar-- any cheap store brand white vinegar will do.
Although mixing vinegar and baking soda is not considered dangerous, you should still avoid mixing these in a container. Vinegar is acidic and basic soda is basic, so the by-products are sodium acetate, carbon dioxide, and water that are not toxic.
Don't fill your cast-iron cookware with wine or vinegar. A splash for sauce or deglazing is OK, but tossing a significant amount straight into the pan undiluted will ruin your cookware, and your health.
All cooking oils and fats can be used for seasoning cast iron, but based on availability, affordability, effectiveness, and having a high smoke point, Lodge recommends vegetable oil, melted shortening, or canola oil, like our Seasoning Spray.
Some are under the impression that acidic foods can discolor cast-iron, but a baking soda scrub should eliminate any discoloring. Some people think that acidic foods cause iron molecules to leach out into your food, but that's actually a good thing!
