Residual mouth alcohol is also known as what?

Explanation:
Residual mouth alcohol is alcohol that remains in the mouth after recent drinking or using mouthwash and can vaporize into the breath sample, falsely elevating the reading. This is simply another way to say mouth alcohol, which is why the best answer is mouth alcohol. The other terms refer to alcohol in different parts of the body (breath, blood, urine) and don’t describe the mouth contamination phenomenon. To prevent this, wait long enough after drinking or mouthwash and ensure a proper deep-lung breath sample.
