Eggshells are not typically used as a cleaning agent for pots and pans. While eggshells have abrasive properties due to their texture, they are not effective for removing stubborn food residues or stains from cookware.
Instead, it is more common to use specific cleaning agents and tools designed for kitchen cleaning tasks. Dish soap, scrub brushes or sponges, and specialized cleaning products are generally more effective in removing grease, grime, and food particles from pots and pans.
If you're dealing with tough stains or burnt-on food, you might consider soaking the cookware in warm soapy water to loosen the residue before scrubbing. There are also various cleaning techniques depending on the material of your cookware, such as using baking soda or vinegar for non-stick pans or stainless steel cleaners for stainless steel cookware.
While eggshells can be useful in certain applications, such as sharpening garbage disposal blades or adding nutrients to compost, they are not a reliable option for cleaning pots and pans effectively.
