Vinegar is used to remove the smell of smoke, but I have absolutely no idea if it would work on something like this!
oh.. and I just remembered a product called X-it. A smell removal spray no longer on the market. According to rumors it contained just salt water with some lemon, sold as crazy and suddenly disappeared.. suspicious eh? Noe idea if it would work either, but in desperation it could be worth a try.
Vlim, like in the old gangster movies.. a truly sign of a bad day, is stepping into the backseat of a car full of chubby people in black suits, only to notice that you are the only one sitting on plastic covers.
