Cleaning burnt-on food from cast iron cookware can be a bit challenging, but with the right approach, it can be effectively removed. Here's a step-by-step guide to cleaning burnt-on food from your cast iron cookware:
Allow the cookware to cool: Make sure the cast iron cookware has cooled down completely before you start cleaning it. Cleaning hot cookware can cause injury or further damage.
Scrape off loose residue: Use a spatula or a plastic scraper to gently remove any loose, burnt-on food particles from the surface of the cast iron. Be careful not to scratch or damage the seasoning.
Create a cleaning paste: If there are stubborn burnt-on food remnants, create a cleaning paste by mixing equal parts of coarse salt (such as kosher salt) and water. The paste should have a thick consistency.
Apply the cleaning paste: Apply the cleaning paste to the affected areas of the cast iron cookware. Make sure to cover the entire burnt-on food residue. Allow the paste to sit on the surface for some time, usually around 15 to 30 minutes. The salt will help to absorb the stuck-on food and aid in its removal.
Scrub the surface: Use a non-abrasive scrub brush or sponge to scrub the surface of the cast iron cookware. Apply gentle pressure and scrub in a circular motion to lift off the burnt-on food. Avoid using steel wool or harsh abrasives as they can damage the seasoning.
Rinse and inspect: Once you've scrubbed off the burnt-on food, rinse the cast iron cookware thoroughly with warm water. Inspect the surface to ensure that all the residue has been removed. Repeat steps 4 and 5 if necessary.
Dry the cookware: Use a clean dishcloth or towel to dry the cast iron cookware completely. It is important to dry it thoroughly to prevent any moisture that can lead to rust.
Re-season (if needed): If the cleaning process has stripped off some of the seasoning or exposed bare metal, it is recommended to re-season the cast iron cookware. Apply a thin layer of oil to the entire surface of the cookware, including the inside and outside, and bake it in the oven at a low temperature (around 300°F to 350°F or 150°C to 175°C) for about an hour. This will help restore the seasoning and protect the cast iron.
Regular and proper maintenance of your cast iron cookware, including immediate cleaning after each use, can help prevent burnt-on food buildup and make cleaning easier in the long run.
