Germicidal bleach is more concentrated than standard bleach, so less product is needed to create a solution for disinfecting surfaces. Apply it to hard nonporous surfaces to eliminate mold, odors, and a broad range of pathogens, including bacteria, fungi, and viruses. The surfaces should be cleaned before applying bleach. Germicidal bleach is commonly used in healthcare facilities, offices, schools, kitchens, and other commercial sites.
