Have not noticed any residual smell at all in house or truck.
I have noticed a residual film from the vapor but only in drinking glasses.
I have found myself completely addicted to playing with my vapor lol.
If I fill a glass with vapor and leave it, it does leave a film in the glass.
Other than that, I have not noticed any other residue.
