RADIUM HAND CLEANER - - Very Radioactive, but - - it would be excellent at killing bacteria. Well, it would kill you too. There was a lot of stupidity in the medical field in the past. They were experimenting on people to see how it worked. The stupidity is more planned now. Like the Pharmaceutical "VIOX". The maker admitted it killed some 35,000 people before they took it off the market - which they knew it would when they put it ON the market.
