Each year, the Museum’s blue whale model gets spruced up in an annual scrubdown.

The 2014 Whale Wash is happening this week, from Monday through Wednesday.

In the Milstein Hall of Ocean Life visitors at the Museum will be able to watch as members of the Exhibition department use long-handled brushes and vacuums to wipe away the dust from the 94-foot long, 21,000-pound model.

Here is a sneak peak of the team getting ready.
