The UK loses a fight with battery acid

[Doc Hudson]

Not to mention producing Chlorine Gas, which has some rather ghastly results of its own. PLEASE, be careful when doing bathroom chemistry.

I know mixing chlorox (a chlorine bleach) and ammonia will release chlorine gas, and BTW make dirty stuff sparkle, but I was unaware that vinegar and chlorine would produce chlorine gas. Are you sure about that?

Yup, very sure. Chlorine gas is made whenever you mix chlorine and an acid, and vinegar is acetic acid. Its not as bad as mixing it with a stronger acid is, but it produces a lot more than you want to be breathing in your enclosed laundry room.
