Remove any visible dirt or debris from the surface you want to sanitize. Cleaning the surface before applying the disinfectant helps the active ingredients work more effectively.

Ensure proper ventilation in the area where you are using the spray. Open windows or doors to allow fresh air to circulate. This is particularly important if the disinfectant has strong fumes.

Hold the spray nozzle at a distance specified on the product label and apply the disinfectant evenly over the surface. Be sure to cover the entire area and focus on high-touch surfaces like doorknobs, light switches, and countertops.

Most disinfectants require a certain amount of contact time to be effective. Check the product label for the recommended duration, and ensure that the surface remains wet with the disinfectant during this period.
