The soleplate for irons comes in different materials like non-stick, ceramic, stainless steel, and aluminum. While stainless steel is most ideal for ironing because of its heat resistance and non-corrosive properties, it can leave marks on the clothes. Ceramic coating, too, works very well but wears over time. An aluminum coating may become less effective over time and stick to your clothes. Each coating is best for different things, so you should consider your personal preferences before selecting. Choose a soleplate depending on the fabrics you want to iron most often.
