"Jackson Pollock's painting Number 1, 1949, is a swirl of multi-colored, spaghettied paint, dripped, flung and slung across a 5-by-8-foot canvas. It's a textured work — including nails and a bee (we'll get to that later) — and in the nearly 70 years since its creation, it's attracted a fair bit of dust, dirt and grime."
"That's where conservator Chris Stavroudis comes in: His job is to clean the painting using swabs, solvents, and tiny brushes. For the last several months, he's been hard at work, once a week, in full view of the public, in a gallery at The Museum of Contemporary Art, Los Angeles."
"Pollock used all sorts of paints — oil paint, house paint, car paint, radiator paint — and they all aged and got dirty in different ways. Working with the Getty Conservation Institute, Stavroudis did tests to see what kind of cleaning was needed."
