"I worked for a pharmacy that would rent out milk extractors, you know breast pumps, for pregnant women. I swear to god I had a toothbrush and a spray, and I would scrub dried milk off the machines," Chris Hemsworth told website Collider, reports aceshowbiz.com.

The 31-year-old is currently filming 'The Huntsman', which is set to release in 2016.
