Only Science Can See™

Mike Berry on the Science of Cleaning

A strong, long-lasting building requires a good foundation. The same is true for a profession or an industry. In our case, cleaning must be based on a solid foundation of scientific research in cleaning principles, processes and products. Such is the kind of work done over many years by Dr. Michael A. Berry. Dr. Berry is the author of a seminal work in cleaning science – Protecting the Built Environment - Cleaning for Health – and was one of CIRI’s founding scientists. As such, he is in a great position to provide the solid foundation you require to be successful in the cleaning industry.



Most recently, Dr. Berry has written a series of articles for The Journal of Cleaning, Restoration and Inspection which serve to update his work in this area. Click below to read these articles and savor the ideas within. Then, apply them to your cleaning activities. You, and our industry will be the better for it.

CIRI's Spring 2016 Science and Research Symposium

By any measure (100+ attendance, participant survey response, etc.), the IICRC/CIRI Restoration Technical Conference and Science Symposium held April 10-11 2016 at Georgia Tech in Atlanta was a great success. Participants heard results of new research on cleaning and restoration science, including:

  • Results from continuing work on ATP as a measure of cleanliness and contamination (Richard Shaughnessy; Greg Whiteley)
  • The results of research on detergent-free cleaning technology from electrolysis (Russ Pylkki, Tennant Company)

There were also wide-ranging panel discussions on experience with the ISSA Clean Standards and future trends in cleaning and restoration science. For a more detailed review of the conference, take a look at The Journal of Cleaning, Restoration and Inspection (June 2016 issue).


And, if you missed the 2016 conference/symposium, check out the following for another great IICRC technical conference in 2017: The Summit at Lone Mountain

“Only science can see.”

For the Cleaning Industry Research Institute (CIRI) it is just that simple.


CIRI’s strong belief in this credo represents a major shift in how the cleaning industry views the future. It also emphasizes the need for high performance cleaning for health, hygiene and appearance.

Evidence shows that cleaning service personnel — no matter how well trained — cannot determine a surface’s cleanliness simply by visually inspecting it. Only science-based cleaning standards can make that determination and CIRI hopes to lead the way in establishing those standards. The Institute is laying the groundwork for developing the basic science for measuring and establishing methods for quantifying clean. A task force has been appointed to assist in these endeavors.
