Bleach and vinegar are both acidic, it's acids and bases (like ammonia. Main ingredient in Windex) that should not be mixed due to the potentially toxic gases they will produce.

So very wrong. Bleach is pH 12 or so.

(Chlorine) bleach mixed with ammonia (which is a base) or any acid, including vinegar, will release the chemical weapon chlorine gas.

Bleach's pH is above 7 therefore it is alkaline not acidic
