Do hygiene products affect breathalyzer tests?

People have been trying to beat the breathalyzer test for many years. There is a myth that sucking on a copper penny causes a chemical reaction in your saliva to make you pass a breathalyzer test if you have been drinking and driving. There is no scientific basis at all for this claim, and today's pennies are made mostly of zinc. Do not try this. Another myth is that breath fresheners, mouthwash, or strong and stinky foods can mask the alcohol in your breath and lower the blood alcohol content (BAC) readings.
