Still smells of smoke

[AndyT77]

Having recently packed in the evil weed, i decided to Vax my car today. I also cleaned all surfaces using some APC, but i can still smell stale smoke in there. I cleaned all carpets, door cards, parcel shelf and headlining using the Vax.

Are these smoke bombs any good? The kind that are a canister that you let off in your car and leave for a few hours, or is there something else i can do? I don't want to spend a fortune, so a detailer/valeter is out of the question.
