Let's go back to "basic chemistry" for a second: Remember those "cloth diaper pails" ??? Remember that ammonia smell from urine in the diapers???

That ammonia smell is present from the uric acid in the diapers (pee)…

Vinegar, (acetic acid) when mixed with ammonia, produces chlorine gas. Chlorine gas is one of the agents banned under the "chemical warfare agreement".

Chlorine gas can cause coughing, watery eyes, irritated nasal and throat tissue and in some people with medical conditions, think lung disease, smokers and asthmatics, can cause a severe reaction or even death....

I wouldn't recommend mixing vinegar with black tank contents. There are much better chemical cleaners to use for that job......
