Found this on one of the sites:
It is very hard to remove hard-set wrinkles from polyester. It will take some time and patience. There is no quick way, you'll need to take your time and use an iron, press cloth and white vinegar. Fill a spray bottle with one half white distilled vinegar and one half water. Lightly spray a small section of the wrinkled area. Use a damp pressing cloth (white lightweight cloth)with the iron set on the polyester setting. Iron from the top to the bottom of the garment in a side to side motion. It may take several ironings to remove all of the wrinkles, but they should be less deep with every ironing.
Not sure if it works, but there you go. No hanging included.
I'll try the first way first...as it is easier as I have to wash stuff anyway
Just made my to Watch list (or currently watching and have to finish)
Serial Experiments Lain (H)
Kino no Tabi (H)
Natsu no Arashi (S)
S=Started, and need to finish
H=Have to start
Any other suggestions? I'm trying to go for tried and true.
