I have a friend who used to work in the fabric industry that told me to use water and vinegar. I keep a spray bottle next to my iron with 1 part white vinegar to 3 parts water. I lightly spray, let it sit a minute, then iron. The smell disappears after a while.
I had complained to her about a panel that had the fold crease down the middle. It took it out. Remember to press - not pull and push the iron across the fabric - it will distort it.
