The New York Public Library has completed a monumental restoration project that spanned  over three years, from 2008 -2011. Part of the work was to clean the 150,000 square foot marble exterior and restore the façade back to it’s original brilliant white colour. In order to achieve this mammoth task, 200 gallons of Vulpex Liquid soap was used to great success. The before and after pictures are quite remarkable!

Below is a video of the press conference and ribbon-cutting ceremony at the end of the project, where the chief architect details the work undertaken. Skip ahead to 10 minutes to see Vulpex in action!
