So used a similar air cone bomb to the one posted above. seems to have worked quite well. have yet to take the car out for a long enough drive to see if the smell has completely gone, but fingers crossed this has worked.
had never heard of these before starting this thread. cos about 8 quid. all you do is run the car for 2 mins with air con on high and in recirc moce, i put the can on the arm rest and you push it down till it clicks and then close the doors. once it runs out you leave the car running for 10 mins and then open all doors and vent for a further 10 and then done! smells like new.
be quite a good thing to do before selling a car
