No matter how nice the hotel room you get is, there will probably be urine and semen stains in it.

In an ABC News Primetime investigation, producers discovered bodily fluid stains in ALL 20 hotel rooms surveyed, no matter the price. Most of these stains are not visible to the naked eye, but they were found everywhere - on the beds, carpets, walls....even on the Bible!

Despite the alarmingly gross results, these stains are completely harmless - no microbes are growing on them because they are dried and sterile. Fortunately, the survey's results convinced many of the hotel managers to train their cleaning staffs to use black lights!
