One lady at work used to say "Why would I have an iron, when I have a perfectly good dryer?" lol
Sometimes I use the Downey spray (tsp of downey with the rest water in a spray bottle,) spray on item, shake/snap while on hanger, no need to drench, and let dry, or put on damp. Feels good on a hot day. No need to iron at all.
My board is wood, paid less that $5.00 at swap meet and is at least 70 yrs. Works good enough for me!
