The steamer has a wand that puts out a focused stream of steam. You put the washcloth directly over the dented area, get the steam nozzle down close to it and give a 15-20 second burst of steam.
The cloth will be wet, and the dent will gradually swell back to level.
This is an example of the kind of thing I'm talking about. I got mine at Goodwill...
