- If you iron once a week or less frequently, and the garments are usually cotton shirts, denim, etc., a stainless steel soleplate will work best for you.  - Otherwise, if you iron more than once in a week and mostly synthetic fiber clothes like polyester, go for ceramic soleplates.  - If looking for a lightweight and rugged iron that will suit all fabrics and also last long, go for irons with titanium sole plates.
