The ultimate clean freaks meet the lifelong slobs in this new series of Obsessive Compulsive Cleaners on Channel Four. Tonight we meet London hairdresser Claire, who spends more than 20 hours a week keeping her one-bedroom flat immaculate. She comes to the aid of 67-year-old former binman Charlie from Hemel Hempstead, who is down to his last unused teaspoon. Meanwhile, Andy from Leicester, who likes to clean things in even numbers, heads to Colchester, where keen historian Ian has amassed a collection of 300 troll dolls. Nowt as strange as folk 'ey?
