Did you make the mistake of setting a hot cup of tea on your beloved wooden coffee table? Odds are, it left behind an ugly white heat stain. Believe it or not, irons can be used to remove heat stains from these surfaces. Place a thin towel over the area in question. Then, set the iron to medium heat, with the steam function on, and apply light pressure to the spot for 10-15 seconds. Check for results, and if necessary, continue applying heat until the stain disappears.
