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.
Apply distilled water to the cotton swab. Use the swab to wipe off buildup from the bottom steam 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.
