Sorry, had to bump this back up. It's quite interesting.
I also got a UV Inova X1 a while ago and have used it (and some amber lenses) primarily for sheer curiosity. This too yielded some rather eye-opening stuff around the house.
Rather than being scared by what I found, I'm actually amazed at what we've lived in and around for so many years without serious harm. That's not to say you shouldn't wash your hands with soap and water, but there's no reason for something like this to make you squeamish.
It's also become clear that there's no possible way to get your house/apartment completely and unquestionably clean. There's always going to be something left over and odds are pretty damn good it's not enough to cause you any harm. If it were, we'd probably have all been hospitalized several times in our life for bacterial sepsis.
Anyway, I wanted to put in my .02...

I'd like an order of BUTTER with extra BUTTER and a side of BUTTER!
