If a crack appears in your cast iron pan, it's time to ditch it. Even a hairline crack will expand and contract when heated and cooled, and ultimately the pan will split—a potentially dangerous situation if it happens during cooking! Plus, cracks are difficult to clean and may harbor bacteria and rust.
Ferrous products (i.e., iron and steel) can be recycled by both internal and external methods. Some internal recycling methods are obvious. Metal cuttings or imperfect products are recycled by remelting, recasting, and redrawing entirely within the steel mill.
There are two types of scrap metal: ferrous and non-ferrous. Ferrous metals include iron, cast iron, wrought iron, stainless steel, alloy steel, carbon, tungsten carbide, and more. Non-ferrous metals include copper, chromium, tin, brass, lead, and aluminum, just to name a few.
Scrap Metal Prices
| Type | Price Per Lb. |
|---|
| Steel | $0.01 |
| Light Iron | $0.01 |
| Cast Iron | $0.02-0.035 |
| Whole Cars | $0.02-0.03 |
You can donate usable pots and pans to Goodwill or the Salvation Army or list them on Freecycle. If the cookware is unusable, contact your municipal department of public works to ask about recycling.
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.
Coke has phosphoric acid, which is a compound that can remove rust. Phosphoric acid is what gives coke its flavor (that I know you love). Nonetheless, it is also what makes it more acidic than any other acids, like vinegar. Coke is a good way to clean cast iron and remove rust from it because it is inexpensive.
Steps to Clean the Outside of the Skillet:
- Begin by boiling water.
- Place the skillet in the sink upside-down.
- Carefully pour the boiling water over the outside of the pan.
- Using caution not to burn your hands, scrub off any food or buildup on the pan with a wire grill brush.
Remove all the rust: Use fine steel wool to remove rust from affected areas. Scour the skillet until the area returns to raw cast iron. Wash the skillet thoroughly: Wash the cast iron with warm water and mild dish soap. Scrub with bristle brush, gentle scouring pad, or mesh sponge if needed.
Step 1: Pour about a quarter-cup of kosher salt and some dish soap into your cast iron skillet. Step 2: Using a washrag, scrub the inside of your skillet exceptionally well. Step 3: Once you are done scrubbing, wash it using hot water.
For Minor Rust Care:While the piece is still warm (but able to handle) pour a coarse grain salt or sea salt in the piece. With a half of a potato or piece of leather scrub the cast. Rinse, heat and repeat as needed to pull out the rust and buff any surface area.
Cast iron and wrought iron are both susceptible to corrosion when bare surfaces are exposed to oxygen in the presence of moisture. This can be challenging for outdoor environments with near-constant exposure to precipitation and humidity. To prevent rust, iron products should be coated to prevent exposure.
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. We only recommend using steel wool or a metal scrubber to remove rust before reseasoning.
What oils can I use to season cast iron? 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.
What happens if I ingest rust? According to the U.S. Environmental Protection Agency (EPA), ingesting rust in small amounts will not harm your health (unless you have a rare disease called hemochromatosis, which causes your internal organs to retain iron).
If your rusty cookware happens to be made of cast iron, most culinary authorities say it's completely salvageable. Experts at the University of Illinois at Urbana-Champaign agree that a little bit of rust on cookware isn't likely to harm you. (Even rust in drinking water isn't considered a health hazard.)
How to Get Burnt Food Off a Cast Iron Skillet
- Remove as much food and debris from the pan as possible.
- Cover the bottom of the pan with baking soda.
- Scrub the pan with a stiff-bristle brush or scouring pad.
- Rinse and repeat if necessary to remove any remaining burnt food.
- Make a paste from 3:1 parts salt and lemon juice.
- Apply the salt-lemon paste with a paper towel.
- Scrub rust away with a scrub pad using firm pressure and small circular motions.
- Wipe the rust and excess rust-removal paste away with a damp paper towel.
In Conclusion. Contrary to what most people think, cast iron skillets can (and often do) break when they fall from a tall enough height. As a material, cast iron is as fragile and brittle as it is heavy and sturdy, so do your best to handle it with care.
That black residue on your cast iron skillet is usually just carbon deposits. It is not harmful. The carbon deposits causing that black stuff coming off your cast iron pan into your food or cleaning cloth form due to the overheating of oil or fats, or bits of burnt food.
If you accidentally leave your cast iron cookware on any heat source for too long, food, marinades, and sauces can burn and get stuck to the surface.
