Put kosher salt in a cast iron skillet: Why Good Housekeeping recommends it for removing burnt food residue

Kosher salt serves as an excellent cleaning agent for burnt food residues on cast iron skillets. Its natural abrasiveness and soft texture work together to eliminate grime without compromising the protective seasoning of the pan. Unlike traditional scrubbers, salt's mild friction helps maintain the polymerized oil layer which gives cast iron its unique properties. Additionally, cooking in such pans may contribute trace amounts of dietary iron, enhancing the health benefits.
