So there is a practice that's about of ironing out dents in wood but it's not well defind. Here is some questions about the technique that in being answered, might make the concept easy enough for others to feel comfortable in using - using the water around the ding to swell the fibers of the wood back to shape. 1) This technique is safe to do on both non-finished and pre-finished furniture. If it works on pre-finished furniture also, is there types of finish that it will or will not work on or will the steam/heat damage a finish? 2) A damp cloth is put over the material to get the dent out of, Iron placed on it. Are you placing water in the dent and letting it soak in first, or using the water within an iron to further steam the dent? Do you do both or one? How long does it take or what do you watch for? 3) Is there an optimum type of cloth to use or some types of material in general to stay away from? 4) How large a ding is this recommended for and how many times can you if at all re-attempt this before it damages the surface? How long before re-attempts. 5) Re-sanding completes the technique, how soon afterwards? 6) And oh' by the way, what temperature should that iron be set at for best results?
