How to get rid of stink of plastic

[eurotrotter]

hi guys,

I took delivery of a new insignia back in december last year.

i have clocked 11k miles since delivery and the interior still stinks of plastic.

I have the elite spec (full leather), and it's really getting to me and my wife now, so I was wondering if any of you guys can recommend something i can purchase to rid the smell?

tbh, i would rather resolve this issue without the use of a perfumed/fragrance substance, as I never use air fresheners, and prefer an odourless cabin.

thank you,
