Unclean surfaces can quickly transform a school into a breeding ground of infectious germs and bacteria that can lead to student and faculty illness, resulting in significant absenteeism. Reduce the risk of illness and protect student and faculty healthy by verifying the effectiveness of cleaning with rapid ATP cleaning verification tests. To aid in this effort, the International Sanitary Supply Association (ISSA) has developed The Clean Standard, a guide to establishing a framework for objectively assessing cleaning effectiveness in schools. The Clean Standard recommends the use of ATP cleaning verification to assess and improve the effectiveness of cleaning processes and products to help keep students well!
