How Clean Is Your House? is a British entertainment/lifestyle television programme in which expert cleaners Kim Woodburn and Aggie MacKenzie visited extremely filthy homes and clean them. The thirty-minute show was produced by Talkback Thames, the UK production arm of FremantleMedia (itself part of the RTL Group), and aired on Channel 4 from 2003 to 2009. Though a ratings success, Channel 4 announced that they had decided to cancel the series in 2009 in order to make way for new programming.SummaryEach episode of the programme followed the same formula. Accompanied by a dramatic score of horror movie music, Kim and Aggie explore the abode on their own, examining the extent of the mess and looking for any particularly horrible areas. Kim and Aggie then meet the resident before the cleaning begins, assisted by several professional cleaners. During this process, which takes up the bulk of the show, Kim and Aggie share tips for tackling particular cleaning tasks with the residents, often relying on traditional solutions rather than proprietary commercial cleaning products.During the cleaning, Aggie takes swab samples from the filthiest areas of the house and has them analysed in a lab, often revealing numerous kinds of bacteria, frequently E. coli or Salmonella. Residents of the homes often have health problems that directly stem from the air quality or pathogens present before cleaning; Aggie will show the residents her findings in an effort to make them understand the connection between their health and their home's condition.
