You may notice that your steam iron is leaving small marks on your clothing whenever you attempt to remove wrinkles from your clothes using the iron. This could be caused by mineral deposits or other particles that are either inside the steam iron or on the plate of the iron. Conveniently, the plate that is located on the bottom of the iron can actually be cleaned by flushing out the interior of the steam iron.
Fill the steam iron's reservoir with equal parts water and white distilled vinegar.
Place the steam iron onto a clean cloth or towel, so that the iron is upright. Make sure that the iron does not fall flat onto the cloth.
Turn the iron onto the "steam" setting. Leave the iron on until the vinegar and water completely evaporate from the steam iron.
Fill the steam iron's reservoir with water.
Repeat steps 2 and 3 so that the water evaporates from the steam iron. Turn the iron off.
Wait about 10 minutes, then wipe the steam iron's plate with a clean, damp cloth. Fold the cloth as you wipe the plate just in case the bottom of the iron is still incredibly hot.
Rinse the steam iron's reservoir once or twice with water. Leave the iron's reservoir open afterward so that it completely dries before you put it away.
