Brown spots on the iron soleplate are typically caused by a buildup of mineral deposits from hard water. When water evaporates on the soleplate, it leaves behind minerals such as calcium and magnesium, which can create brown spots over time. Additionally, using the iron at too high of a temperature or ironing over certain materials, like synthetic fabrics or starch, can also cause brown spots to form. Regular cleaning and maintenance of the iron can help prevent and remove these brown spots. **
