Hi, I bought a second hand pushchair. I checked before I bought that it was from a smoke free house and seller said it was and when my husband picked it up he said house didn't smell of smoke. However when we got it home noticed it does have a stale smell (not sure if old smoke or not) and when I wash covers (which looked clean) lots of orange stains are coming out. Does this sound like staining from cigarettes? And if it is would you keep and clean up or just get rid of it? It was only cheap but we are a bit strapped for cash at the moment. Thanks
