Cold Jet and ACP Helping to Preserve Auschwitz Artifacts

Precision dry ice blast cleaning system allows conservators at the Auschwitz-Birkenau Memorial and State Museum to effectively clean metal and ceramic items safely

In an effort to preserve artifacts from the Auschwitz concentration camps, the Auschwitz-Birkenau Memorial and State Museum in Oświęcim, Poland has turned to Cold Jet, LLC and ACP Group, a leading European  producer of liquid carbon dioxide and dry ice. Conservators at the museum will use Cold Jet’s i3MicroClean precision dry ice blast cleaning system and dry ice from ACP to clean metal and ceramic objects, including prisoners’ bowls and spoons. The museum will also use dry ice blasting for maintenance of the facilities housing the planned new main exhibition. Recognizing the global significance of this cultural renovation project, Cold Jet and ACP provided the museum the blasting system and the dry ice at special symbolic pricing. The financial contribution from Cold Jet and ACP for this project is therefore well appreciated by the museum.


“The museum is in the middle of a global conservation and preservation project of the Auschwitz-Birkenau camps, which include 155 buildings and thousands of objects from prosthetics and glasses to cookware and art,” says Aleksandra Papis for the Auschwitz-Birkenau Memorial and State Museum. “Our modern laboratory and skilled restorers are working to find the best and safest methods for restoring all aspects of the camps. After significant testing of the Cold Jet system, we were satisfied with the ability to clean many of the unusual objects that will be displayed throughout the museum. We found dry ice blasting to be cleaner and less abrasive than other methods, and we will continue to find new ways to use the system for general maintenance and throughout the duration of the cleaning and preservation project.”


“The preservation of the Auschwitz artifacts is important from historical and social perspectives as the museum works to provide its more than one million annual visitors with a clear understanding of the atrocities that took place in the camps, as well as an honorable way to memorialize the victims,” says Dietmar Juchmes, General Manager of Cold Jet Germany. “It is important for Cold Jet to be involved in this project to demonstrate our commitment to social causes by using our modern technology to preserve the past. Our dry ice blasting systems have been used to restore everything from soot-covered books damaged in fires and raised wreckage to established landmarks. Each presents a unique challenge that has been tackled by one of our dry ice blasting systems.”


The i3MicroClean is a precision system used around the world to clean everything from delicate surfaces to complex mold cavities. The system uses reclaimed CO2 in the form of solid dry ice particles accelerated through a hose and high-velocity nozzle to remove coats of resin from metal objects and dirt from ceramic objects without damaging the metal or ceramic. The dry ice particles vaporize upon impact with the surface, cleaning without any by-product and eliminating the added cost and environmental impact of secondary waste treatment and disposal.


Jan Vansant, general manager of ACP adds, “We are honored to be working with the Museum and Cold Jet on this important social project, which demonstrates our companies’ commitment to social ethics and conscientious sustainability. The use of dry ice blasting as part of this restoration project enhances the museum’s ability to quickly and safely clean its vast inventory of important cultural and historical artifacts. We are pleased with the results of the dry ice blasting performed on the artifacts and look forward to assisting the museum going forward.”
