Overview: The first cleaning volunteer is 23-year-old council worker Dann, from Nottingham. Dann replaces his loo seat once a month and regularly bathes his cats in flea treatment. Dann helps out Charlotte and Dom, from Portsmouth, who haven't cleaned their flat in a year. The second volunteer is Angela, from Nottingham, who gets through three bottles of bleach a week. Angela meets Lorraine, from Scarborough, who hasn't cleaned her kitchen for two years. And OCD-diagnosed Alison takes on Helen to see who has the most spotless kitchen cupboards.
