When to Use Disinfectant
Choose a disinfectant when you need to eliminate pathogens completely. Restrooms, sick rooms, shared equipment, door handles, and any surface during cold and flu season. Always follow the listed contact time on the label for full effectiveness.
When to Use Sanitizer
Choose a sanitizer for food-contact surfaces, daily kitchen cleaning, dining areas, and break rooms. Sanitizers work faster and are designed for areas where food safety regulations require specific products that do not leave harmful residues.
