Cleaning the bottom of an iron requires dissolving buildup and purging the steam vents. The process takes about 20 minutes, and it requires distilled water, baking soda, white vinegar, a rubber spatula, a cotton swab, a damp cloth and a dry cloth.
- Apply baking soda paste
Mix together 2 tablespoons of baking soda and 1 tablespoon of distilled vinegar. Use the rubber spatula to apply the paste to the bottom of the cold, unplugged iron. Use the damp cloth to wipe off the paste.
- Wipe the steam holes
Apply distilled water to the cotton swab. Use the swab to wipe off buildup from the bottom steam vents.
- Clean the vents
Pour out old water remaining in the iron. Add 1/4 cup white vinegar and 3/4 cup distilled water to the reservoir. Set the iron to its hottest temperature for several minutes. Iron a dry cloth, using steam to flush out the vents. Unplug the iron, and drain the reservoir.
