Germicidal Bleach, with a concentration level of 8.25 percent, cleans, disinfects and deodorizes a variety of surfaces. It is EPA-registered to kill 39 organisms, including multiple strains of MRSA, Norovirus and three strains of influenza. This bleach kills Clostridium difficile spores in 5 minutes on hard, nonporous surfaces when used as directed. Suitable for food-contact surfaces, it kills salmonella, E. coli and listeria. With the higher concentration level, dosage requirements for general disinfection are cut in half, providing better value and a smaller, easier-to-handle bottle. From Clorox Commercial Solutions, germicidal bleach is ideal for use in busy healthcare environments, offices, schools and other commercial facilities.
