Interesting thread. I'm not overly concerned about lavatory brushes - no one handles the business end and as long as they are rinsed after using, what does it matter? Its on a par with the ads about keeping your floors germ free with various products: WHY?? Floors just need to be socially clean. When did we see commercials that demonstrate cleaning the flush handle & door handle? Those are the bits that needs keeping clean. And while I'm at it, closing the lavatory seat before flushing.
I was wondering by what possible mechanism the germs on the despised toilet brush could be transferred to the people using the toilet. It's not as if people using it actually handle the business end and bacteria don't actually go anywhere unless, as has been found in research studies, they can be dispersed via droplets when the toilet is flushed with the lid open.
As to 'dirty' flush handles and door handles, surely proper hand washing would deal with that? Washing hands thoroughly after flushing deals with anything that may have been transferred from the flush handle/button and opening the door with those clean hands won't leave anything on the door handle.
