I bought some grommet top thermal drapes today for our bedroom and they say "dry clean only" on them. They are covered in wrinkles from being packaged. Is there any easy way to get these out without ruining my new drapes? Can I throw them in the dryer with a wet wash cloth? I bought some velvet blackout drapes for my son's room and that was what they recommended for getting wrinkles out, but I wasn't sure if I could do it on the "dry clean only" drapes.
