My grandad has recently become so ill that he's now been medically advised not to continue driving. He was driving a 2005 Fiesta, and enjoyed smoking in it regularly, mixed with ferrying around his dog, as such it's left quite a strong smell in the interior of the car.
I've now taken ownership of said car, and wondered what is the best way to get rid of the smell? I've vacuumed the car and wiped everything down, sprayed some interior odour eliminator and let it air for awhile, but it's still clearly quite pungent. Any ideas of what I can try next to lift the smell? People have advised car smellies but I'm inclined to remove the smell rather than mask it.
Any advice welcome (short of throwing a match on the car and being done with it)...
