A buddy in college forgot a gallon of milk in his car and it was out in 100+ degrees the whole weekend. He opened his car Monday morning and almost fell over from the smell. For the last year and a half at college his car smelled even though he tried everything to get rid of the stench. First he tried air freshner but that only made it smell of sour milk and air freshner, etc.

Get a new floor mats and maybe the dealer can remove the carpet and pad(?) assuming that it soaked in there too and have it replaced.
