I've seen all the episodes, so I don't watch anymore. I wish they'd show the American version on Lifetime I heard about again. I'd love to see them scream and gag over filthy American homes!
I've been into "natural" home cleaning for quite a while since I'm chemically sensitive. The so-called "biological washing powder" is what we call "ecological washing powder" and can be found at health food stores. The one I use is made by Ecover.

The great thing is that it cleans way more stuff than just clothes. I used to clean the gunk that had accumulated in the bottom of my dishwasher and it was the
only thing that worked! But it does great with clothes, too. It's the enzymes that do the trick.
One thing that surprises me about the ladies cleaning solutions is that I've yet to see them use hydrogen peroxide. I make extensive use of it. You can find concentrated food-grade versions at health food stores also. You just dilute a tiny bit with distilled water and use to disinfect everything including your fruits and veggies. It's fantastic substitute for bleach which is very caustic and toxic and bad for the environment.
