Melted fabric on the bottom of a steam iron occurs when the iron is placed on a heat setting that is too high for the material and causes the fabric to burn onto the iron. The melted fabric may smell, interfere with proper ironing of other clothes and can transfer stains to other material. However, there are a few cleaning techniques that will remove melted fabric from the bottom of a steam iron.
Purchase a stain erasing sponge at your local grocery store, drugstore or hardware store and dampen it. Scrub the bottom of the iron and remove as much of the melted fabric as possible.
Combine ½ cup water and ¼ cup baking soda and mix until a thick paste is formed.
Spread the paste on the bottom of the iron over the melted fabric but avoid plugging the steam holes. Let sit for 30 minutes.
Dampen a clean cloth and scrub the paste off the bottom of the iron. Wipe until clean.
If residue remains on the iron combine ¼ cup vinegar and ¼ cup salt in a microwave safe container and heat for 30 seconds in the microwave. Use a clean cloth to scrub the mixture onto the bottom of the iron. This should remove any remaining fabric from the iron.
Dampen a clean cloth and wipe the iron until completely clean. Let dry before using.
