Des Moines’ City Hall Gets A High-Tech Cleaning
What do Mount Rushmore, St. Peter’s Square in the Vatican City, and the The Colossi of Memnon in Egypt have in common with the Des Moines’ City Hall? According to an article on the Medium Corp. website, they've all been cleaned with high-tech cleaning gear.
For the past 40 years, Kärcher, a German-based company, has worked on nearly 180 historic monuments, landmarks and buildings around the world through its cultural sponsorship program in which the company provides free cleaning for cultural sites.
The City Hall was in the middle of a two-year rehab project when Kärcher’s technicians started last October. The team used steam pressure cleaners to remove algae, fungi, lichens and deep-seated spores without damaging the building’s limestone exterior and granite base.
“You could see the dirt (just rinse) off the building,” Jason Van Essen, a senior planner for the city of Des Moines, said in the article. “It’s nice to have that exterior work tie in with the internal work that was being done.”
Kärcher’s technicians will return to Des Moines in July to clean the historic Police Station .
“The cultural sponsoring program is something we do in the spirit of a good corporate citizen to make a difference,” program leader Rich Barry, said in the article. “It’s important to us and our customers that all this effort is focused on these historical treasures so they are preserved for future generations.”
