This is what I learned at work today:
Do not take Clorox (or any other cleaner for that matter) and pour it out of its bottle and put it into a cup, especially not a sippy cup that actually belongs to the not quite 18-month-old who lives at the house and may actually be able to reach the cup and get a drink.
Apparently the majority of accidental ingestions of cleaners occur because they were put into a bottle or cup where they don't belong.
This is what else I learned:
Clorox (surprisingly) is not actually that bad for you. I mean, I'm not recommending that anyone go out and drink it, but the kind that people have around the house does not really do that much damage.
