I have often regretted not reading Sarah Krasnostein’s reputedly brilliant The Trauma Cleaner, a creative nonfiction account of the life of Sandra Pankhurst. She ran a business that cleaned up after deaths, hoarding, squalor … anything messy and disgusting. “Clean” is a documentary revisiting Pankhurst and her business half a decade later. Director Lachlan Mcleod stays in the background as he follows the trauma cleaners into horrific situations, then interviews Pankhurst, now a minor celebrity who gives motivational talks. A fascinating tale that turns poignant, Clean offers little drama but is a well-executed peek into a world most of us never knew existed.
