On behalf of our entire dedicated team, it is with great pride and excitement that we announce the release of the first-ever ANSI approved standard for the built environment. This landmark achievement represents a significant step forward in supporting professional cleaners by providing a comprehensive and authoritative resource to enhance their expertise. This new Standard is designed to empower cleaning professionals with practical guidance on the current Standard of Care, elevating the industry’s standards and fostering a healthier, safer built environment for all.
