3rd hand smoke and used baby stroller

Hi.

So I just bought a basically brand new Stoller/baby carrier and everything checked out (brand new 3 months ago and she found it too heavy to walk up 3 flights thus why selling). And as I pull it out of the car I could smell a very faint cigarette smell. Never noticed it when we tried out the stroller. Our baby isn't due anyways for 6 months, so will it be ok to use come March or is there still a lot of 3rd hand smoke issues attached to the fabric?

Is there a way to remove the hazards?

Should I try to sell it back to her?

This is our first and probably only baby and I don't want to screw anything up.

Thanks all
