The document discusses the challenges of cleaning in schools and the benefits of adopting "cleaning for health" practices. It notes that schools are densely occupied spaces where children, who are more vulnerable, spend many hours. Traditional cleaning products can negatively impact health. Cleaning for health uses certified green products and practices to improve indoor air quality while protecting occupant and worker health. Studies on schools that adopted these practices found reductions in airborne dust, chemicals, bacteria and fungi as well as health benefits.
