We've heard about how dirty our telephones, keyboards, and bedsheets are, but how about your shopping cart? Seems they're not that clean either. And why should they be when little 5 year-old Johnny is sneezing and drooling all over the handle?

PureCart Systems is a company that hopes to make your next grocery shopping experience a little more hygienic. PureCart is basically a drive-through car-wash for shopping carts. A sanitizing solution is sprayed on to each passing cart, killing everything upon contact.
