I think I'll try a one two combo with a bowl of vinegar and a bowl of baking soda.
UPDATE: Looks like they only sprayed the carpeted mats thank God.
I took him out of the car and replaced with my BMW all weather rubber mats- I've been meaning to do that for the winter time anyway.
Threw the "contaminated" carpeted mats on the porch in the sun.
Hopefully by the spring or summer they will be all aired out and free of that noxious odor
