Finally there is mouth wash, there is only one comercially available m/w in UK that I am aware of that does not have an alcohol-based carrier. If you want an interesting time at security go to toilets just before passing through and run some Listerine round your mouth, your colleagues can run book on you getting stopped.
Not a wise thing to do , if you do get stopped and breathalised you run the risk of failure of the breath test - which is why if you get stopped whilst driving prior to the breath test you will be asked if you have used mouth wash in the prior 20 minutes. To confirm the non-presence of alcohol should you state you have used mouthwash requires a blood test - this all takes time and would mean you probably would not make the flight and cause disruption.
