Disinfectant spray is a cleaning product designed to kill germs, bacteria, and viruses on surfaces. It typically contains active ingredients like alcohol, bleach, or quaternary ammonium compounds that help eliminate harmful microorganisms. Disinfectant sprays are commonly used in homes, schools, and healthcare settings to maintain hygiene and prevent the spread of illness. To use disinfectant spray effectively, it is important to follow the instructions on the label. Most sprays require the surface to be cleaned first, followed by an application of the disinfectant. After spraying, the surface should remain wet for a specified time to ensure proper disinfection before wiping or air-drying.
