Farmer - I've read that too. I will try it along with leaving charcoal in the car. However, I have heard that ozone and smoke bomb treatments are the only effective way to get rid of it permenantly since the smoke is sitting in the headlining and the seats etc. I read that the ozone/smoke bomb thing actually kills the bacteria that cause the smells but it all sounds a bit sci-fi to me.

I'll pop down to tesco's and grab some bicarbonate soda - it doesn't effect the colour of the carpets or anything does it?

Cheers,
AAK
