Cleaning Britain’s Greatest Treasures

This series follows the work of some of Britain’s vast army of dedicated conservation cleaners who preserve and protect millions of our national treasures. At locations ranging from stately homes and museums to historic churches and industrial revolution factories, they show us the special tools, techniques and tricks of the trade they use to clean and preserve all sorts of treasures and artefacts. As they work, they share their passion and insights into the objects and their original owners as well as fascinating, little known gems of history… and sometimes they even solve their mysteries.

In this clip, conservation engineer, Samuel Wilson and his team are cleaning the dirt and grime from St Marylebone’s delicate, hand-carved, two-hundred-year-old neo-classical stonework. And they think some of the dirt may date back from the time Charles Dickens was a local parishioner.
