To remove burned-on grease from the bottom of pots and pans, especially those without Teflon coating, you can follow these steps:
Allow the pan to cool: It's important to let the pan cool down completely before attempting to clean it. Working with a hot pan can be dangerous and may also make the cleaning process more difficult.
Scrape off loose debris: Use a plastic or wooden utensil to gently scrape off any loose or burnt food particles from the bottom of the pan. Be careful not to scratch or damage the surface of the pan.
Soak in warm, soapy water: Fill the sink or a basin with warm water and add a few drops of dish soap. Submerge the pan in the soapy water and let it soak for at least 30 minutes or longer, depending on the severity of the burned-on grease.
Use baking soda or vinegar: If the grease is stubborn, you can make a paste using baking soda or create a vinegar solution. For the baking soda paste, mix baking soda with a small amount of water to form a thick paste. Apply the paste to the affected areas and let it sit for a while before scrubbing. For the vinegar solution, mix equal parts vinegar and water and bring it to a simmer in the pan. Allow it to simmer for a few minutes, then scrub the pan with a non-abrasive scrub brush or sponge.
Scrub the pan: After soaking and using baking soda or vinegar, scrub the pan with a non-abrasive scrub brush, sponge, or nylon scouring pad. Focus on the areas with burned-on grease, applying gentle pressure and using circular motions. Be cautious not to scratch the pan's surface.
Rinse and inspect: Once the burned-on grease has been removed, thoroughly rinse the pan with warm water. Check for any remaining residue and repeat the process if necessary.
Dry and condition: After rinsing, dry the pan thoroughly with a clean towel or allow it to air dry. Optionally, you can apply a thin layer of cooking oil to the pan's surface to condition it and prevent future sticking or rusting.
Remember, the cleaning method may vary depending on the specific material of the pan, so it's always advisable to refer to the manufacturer's instructions or recommendations. Additionally, it's important to avoid using abrasive cleaners, steel wool, or metal utensils that could scratch or damage the pan's surface.
