I have heard of steam irons left standing would cause them to leak and sputter water. This may be true since most steam irons do this over time. I'm guessing you turn the baking pan upside down to lay the iron on the bottom, the air inside would help keep the pan cool. I like to use the silicone ironing pad. It doesn't get hot. Maybe put the pad on the pan to keep it elevated as I do tend to touch the iron if left flat to the board. Thanks for the tip.
