How Long Does The Effect Of Listerine Mouthwash Remain In The Mouth?

Can alcohol in mouthwash affect a breathalizer test?. Is it true that it is unsafe to use a mouthwash with an alcohol content of 21o/o ?

    depending on how soon you have to take a breathalyzer test, it actually could affect it…but i don’t think the effects last longer than an hour or so…eat something if you’re worried about it, or use the Crest Alcohol-Free Mouthwash.
