I left all of my dance outfits (leotard, ballet shoes, tights, etc) in the same CLOSED bag as a subway sandwich for 3 months. i forgot about it and found today. there is a nasty, horrible stench left on it, and i've already washed it 3 times and sprayed a bottle of febreze on everything. what can i use that is cheap but will get the odor off of everything? otherwise will have to buy new stuff that will cost me hundreds of dollars! HELP MUCH APPRECIATED!
