No need to push the steam button on the iron. Just place the generously damp rag and press the hot iron on the dent. Lift iron and rotate the rag as needed to create as much steam needed to pull the dent outward. To be expected, the steam is hot so keep your hands and fingers away. It may take several attempts so be patient. For superior results, you need to have the dent cleared of the old top coat finish so the water can penetrate the raw wood. i.e. oil, lacquer, polyurethane etc. Good luck. JTWhen you do this, are you just heating the damp cloth, or are y'all pressing the steam button?
