i was going to suggest febreze and viniger also but was beat to it but then got to thinking maybe instead of washing the material in vinegar ( which i do believe would work) you could put the material (layed out loose) in a box and set a cup of vinegar in with it ,cover the box with a lid and make sure no one can bump into it maybe the smells would be be absorbed in the vinegar sorry this happened
i would also let the person you bought it from know what happened maybe they can make it right , i would leave a comment about the smell in my feedback about the seller so it doesnt happen to anyone else
