Yes, any old clothes iron works,
but the experience is never very satisfying, what with all those steam holes filling up with wax. And unlike other waxing irons, Toko's WaxMouse ($74, tokous.com) is inexpensive enough to justify its inclusion in a home ski-tuner's tool kit. It's simple and compact, so it travels well. A step dial makes it easy to control temperature (important in avoiding potentially noxious smoke). And it generates enough heat for even the hardest of cold-snow waxes.
