Are Green Cleaners Really Effective?

When I used to work at group homes I was known by some as the "germ boy." Why, you might ask? Well, it wasn't because I am a walking talking vector for germs; rather it was because of my propensity to use chemical dis-infectants around the group home for everything from the floors to the counters and door handles.
I have often touted, especially to young mothers, the wonders of a product known as Benefect which is 100% natural (and by the way, Canadian) and 99.9% effective in killing all those nasty household germs. The kicker is you can spray Benefect directly into your mouth and it will do you no harm whatsoever. Which means you clean any given surface, wipe and then spray Benefect and forget about it. It is even safe on kitchen counters.
I was happy to come across this very informative article at slate.com which explores and explains which "green" cleaners work and which may work.
Read, enjoy, kill!
