It really is that simple. You want to concentrate "Steam" in the spot you want to lift. I have even gone to using a flat tip soldering iron. Don't let the towel or pad, go dry or it wil burn Your work. I try to stay plenty thick on the towel or cotton cloth. You may have to repeat the process on the deep areas.towel should be wet but not dripping. iron on high
Have never tried it and can't see how it will work. Remember that you you want concentrated "Steam". Irons work !!Would a heat gun be OK, or would it get the wet towel too hot?
