Drop that Clorox!!!
Is there corroboration for this?
Bleach is used everywhere for disinfection...to assert that it  
actually promotes the growth of more nefarious germs is revolutionary.

How is bacteria growth tested, anyway?

Those MythBuster fellows on TV tested toothbrushes that they  
strategically placed all around the house, to determine if putting  
your toothbrush on the back of the toilet is any worse than, for  
example, hanging it up next to the medicine cabinet or putting it  
under a bell jar in the kitchen.  They followed a scheme of using a  
different toothbrush every time they brushed, and putting it back in  
the same place.
At the end of the test period, every single toothbrush tested  
positive for fecal coliform, including the one under the bell jar.
I think they implied that they sent the brushes to a lab.

Pleasant thoughts,
Jason
