Help! Cigarette smell in pack n play.

My aunt bought me a pack n play while I was still pregnant along with a mattress for it and mattress covers. It's one that has a changing table and bassinet on top. It sat in her house, in the box, for 2 months. She is a heavy smoker but I did not think anything about it since it was in a box and carrying case. My son was born on the 2nd and we just put it together today. I didn't smell anything at first but I picked my son up from his nap and he smells like cigarettes!!! How do I go about getting the smell out? I have a regular bassinet but the mattress is getting a little warped already and it causes my son to roll to one side while sleeping. I'm not comfortable letting him sleep in it anymore but I also hate him sleeping in a cigarette smelling one too 😒
