Remove marks from the base of an iron easily with this guide so you can iron smoothly and at ease. Buildups of starch, laundry detergent and fabric softener cause these stains. Additional causes are dust, using fusible fabrics when sewing and ironing synthetics at a higher temperature than recommended. You must take care when cleaning your soleplate not to damage with abrasive cleaners.
Rub until you remove all the stains. Repeat with a clean cloth to remove any excess cleaner.
