A Time to Clean

Britain's dirt detectives, Kim Woodburn and Aggie MacKenzie, from Lifetime's How Clean Is Your House, are on the case to track down the dirtiest homes in America. After close inspection, these ladies roll up their sleeves and start scrubbing. Using an arsenal of scientific testing devices, the clean queens can detect what bacteria are taking over these homes in order to better kill them. When all the deep cleaning is complete, the homeowners have a brand new spotless home. For Kim and Aggie, cleaning other people's homes is truly a labor of love.

The most surprising thing Kim and Aggie find about these extraordinarily messy people is that you might not even know it to look at them. "On the street they look well groomed," Aggie says. "Well dressed. And you go into their houses: chaos!"
