I have a portable iron I keep in my service case for in home work; it doesnt
have a "well" for a sponge, so I use a "wipe away", made by Fort Howard. Looks
like a really heavy duty paper towel, but it must be some kind of treated
paper, cause it doesn't burn when I wipe the tip with it; one will last me
about 6 months before it gets too cruddy looking.
