Before you try the cleaners, try these steps first:

1. Just hang it up for a while. If the wrinkles aren't too bad, the weight of the hanging pleats will pull out any wrinkles.

2. If you can get a hand held steamer, run a little steam over the pleats to loosen the cloth, then tug gently but firmly at the bottom of the pleats to pull out the wrinkles.

You can always go to a cleaner if these don't work.
