I keep seeing adverts that state that the product kills 99.9% of germs
dead. What can't we have a product that kills them all, like Screen?

I think it's because the manufacturer has no way of proving 100% killed, or something like that.

more cynically, I reckon it's so no one can sue the b@stards when
they've relied on any "100% kill" claim.
