Richard & Linda and Louise & Michelle (S02E04)

Richard, hailing from Hastings, meticulously bleaches and scrubs his fridge four times a week. He lends a hand to Linda, a dog minder from Brentwood, Essex, who often cares for as many as ten dogs simultaneously. Meanwhile, Louise, from Wiltshire, cleans her sink an astonishing eighteen times each day and makes the trip to Swindon to assist Michelle, a confirmed hoarder.
