Is it safe to put purrell on a wart?

Probably: If you are referring to a common wart as on a hand or foot, sure, it seems unlikely that any soap product would be dangerous. I presume most folks would not put such a product on their genitals anyway, but purell might be a bad thing for a genital lesion such as a genital wart. On other other hand, it is highly doubtful that anything like purell will remove a wart either.
