Vintage-stall owner Sarah, from Ely in Cambridgeshire, has so much clutter that she has filled sheds, a gazebo and much of her house with her hoard. Volunteering to help Sarah is OCD-diagnosed Louise, who cleans daily for eight hours and wipes the door handles in her home hundreds of times a week. Meanwhile, forecast analyst Adam visits Lara in Rochester, Kent, and discovers her property hasn't had a deep clean for 12 years.
