Caren, from Warrington, cleans for at least four hours a day and her cat is only allowed outside on a lead. Caren meets Linda and her son Matt, who have being living amongst grime for nine years and have out-of-date food from the 1990s. The second volunteer is OCD-diagnosed Jamie, from Somerset, who can't stand any form of clutter, uses so much bleach it burns his eyes and must check the door 16 times before he leaves home. Jamie meets Mick, from North London, who lives in a one bed flat filled with clutter and grime. But getting Mick to let go of his precious belongings is not going to be straightforward.
