I don't know where to post this, but I am hoping someone can give some advice. My daughter is ready to sleep in her own bed, and I have saved a mattress from my son's first bed for her to use. Unfortunately, the mattress has been in our furnace room for 2 years because our last house was very tiny and we had no other storage space. The mattress was covered in a thick, plastic mattress bag and was not located too close to the oil burner or any of the furnace equipment; however, when I took the mattress out of the bag, I noticed it had a faint oil smell to it. It's the kind of odor you'd only notice with your face pressed close to the mattress, but of course, my daughter will have her face pressed into the mattress each night! I am thinking I can leave it outside in the hope that it airs out, and then it might be okay...I really can't afford to purchase a new one at this time, since I just bought a new home. Any suggestions or opinions?
