I usually put them in the clothes dryer on low with a damp wash cloth. The moist heat removes the wrinkles. It just takes a few minutes. Watch closely so you don't damage the cloth.

Put it in the dryer just for a few seconds, enough to warm it up good. It will soften the plastic and the wrinkles fall out.
Take a soaked washcloth and put the tablecloth in the dryer with it. Run it for about 7 minutes, then check and add more minutes as needed. I do this with my shower curtain after I wash it. It works. (02/05/2010)
