DAZO® Environmental Monitoring System

Help ensure your team delivers the cleaning disinfection results you expect with Ecolab's DAZO® Environmental Monitoring and Verification System to objectively measure the thoroughness and consistency of cleaning on critical surfaces and high-touch objects in hospitals, healthcare and institutional facilities. 

Measuring Results and Delivering Outcomes

Studies have shown the environment to be a contributing factor to the spread of pathogens, and should be an area of focus in a complete infection prevention programme. The CDC Toolkit: Options for Evaluating Environmental Cleaning, acknowledges the environment's role in the spread of infections, and the need to take preventative action to continuously evaluate and improve environmental cleaning to reduce associated risks.

  • In peer reviewed studies, DAZO® Fluorescent marking gel is the most widely used and accepted environmental monitoring tool (Studies available upon request)
  • DAZO® provides objective evaluation of critical cleaning outcomes
  • Real-time, online cleanliness reports help drive continuous improvement and provide compliance with current recommendations
