So I used space saver bags to store my yarn in my storage unit. Since I am not moving out any time soon, I got it out of storage. I have about 300 skeins if it. It stinks of plastic I will have to let it air out I guess. I am getting a massive headache from the smell of that plastic stuff.

If airing it out doesn't work, you can wash it. Yes, even wool.
Skein it it (easiest if you have a yarn swift, but the back of a chair or 2 works), tie it off in a few sections, then soak in a tub of water with a bit of shampoo or baby wash.
Rinse, squeeze and hang to dry.
