Recently I spotted this in the toilets...

Does anyone else see something wrong with the wording?

*Can* kill *99.9%* of *most* germs that *may* cause illness. Doesn't sound *that* reliable, does it? Oh well, it smells of Vodka, good for getting in the mood on Friday

Apologies for the poor photo quality, there is only so long I am prepared to stand in the toilets with a camera.
