Choose enamelled or bare cast iron with the care routine in mind, not just the colour or weight. Enamelled cookware has a manufactured surface over the iron; seasoned bare iron relies on a maintained seasoning layer. Both need care, but the same cleaning or restoration method does not belong on both surfaces.
Rust on a bare cast-iron pan may be a restoration problem rather than a reason to discard it, but identify the pan and inspect its condition first. A sound seasoned surface with limited rust is a different case from damaged enamel, a cracked body or cookware with an unknown history.
Season a carbon steel pan using the first-use method supplied for that exact model. Begin by identifying whether it is uncoated, pre-seasoned or factory coated, then check the handle and permitted heat source. A method that suits one bare steel pan can be inappropriate for another pan with different fittings or preparation requirements.
Some non-stick pans are dishwasher approved and others are not. Even when dishwasher use is permitted, the manufacturer may recommend handwashing to preserve the finish. Read the exact model’s care instructions rather than treating the words non-stick or dishwasher safe as a complete cleaning routine.
Replace a non-stick pan when its coating is damaged in a way the manufacturer says requires replacement, or when another fault makes it unsuitable for use. Do not rely on a universal age limit. A calendar cannot tell you whether a particular pan has been lightly used, overheated, scratched or stored badly.
Rainbow marks on a stainless steel pan do not automatically mean that a coating is peeling or the pan needs replacing. First check whether the surface is uncoated steel and whether the mark is simply a smooth colour change. Raised deposits, rough pits and separating material need a different assessment from a coloured sheen.
