Salt is not a universal fix for a burnt pan. Identify the cooking surface first: seasoned cast iron, enamel, stainless steel and a nonstick coating can need different care. A method suitable for one may damage another.
Let the pan cool before cleaning
Set it on a heat-safe surface and follow its care instructions. Le Creuset warns against putting a hot pan in cold water, because thermal shock can damage enamel. Do not scrub a pan while it still contains boiling cleaning water.
Seasoned cast iron
Lodge’s routine guidance is to wash with warm soapy water, dry completely and apply a thin layer of oil. For stuck food, it recommends a nylon brush or pan scraper; it advises against soaking cast iron.
Lodge also mentions a nylon brush or salt for removing flakes of seasoning, followed by rinsing, drying and oiling. That is a specific care situation, not proof that salt will restore every scorched pan or damaged surface.
Stainless steel
Le Creuset recommends a soft non-metal sponge, warm water and mild dish soap for its stainless-steel cookware. For stubborn residue, its guidance includes soaking and suitable stainless-steel cleaning methods. Check the instructions for your own pan before using a cleaner.
Its care guide also warns that adding salt to water before boiling can contribute to pitting. A prolonged salt-water soak or boil should not be presented as a universal stainless-steel cleaning recipe.
Enamel or a nonstick coating
For Le Creuset enamel, let the pan cool and use a soft sponge or brush with mild dish soap. Its burnt-food guidance includes a warm soapy soak, then cooling and gentle cleaning. Do not transfer a bare-iron scrubbing technique to enamel or a nonstick surface without the manufacturer’s approval.
If the surface is damaged
Cleaning away food is different from repairing a coating or crack. If you find peeling, chipping, warping or other damage, check with the manufacturer about continued use. Salt, lemon and a potato cannot be assumed to make damaged cookware usable again.
