Residual mouth alcohol is also known as?

Explanation:
Residual mouth alcohol refers to alcohol that remains in the mouth after recent drinking or use of mouthwash, which can contaminate the breath sample. This is precisely what is meant by mouth alcohol. It’s different from breath alcohol (the alcohol in alveolar breath), blood alcohol (in the bloodstream), or saliva alcohol (in saliva). Recognizing this helps explain why a breath test can be affected if mouth alcohol is present, and why retesting after the mouth has been cleared may be necessary.
