Sarah, Andy & Mikk and Ben & Gerri

Ben spends up to two hours a day cleaning his kitchen hob despite the fact he has only used it once, and doesn't sleep in his bed for fear of creasing the sheets. He heads to Guildford, Surrey, to meet upholsterer and craft enthusiast Gerri, whose home is stuffed with three years' worth of material waiting to be upcycled. Also waging a war on dirt is Sarah, who became obsessed with cleanliness after having her first baby. She travels to Coventry to help brothers Andy and Mikk, but is shocked to find an untidy living room and a wall being used as a dartboard on her arrival.
