Can I apply a product using a method that is not specified in the directions for use?

Any time you use an EPA-registered disinfectant, you should read the product label and follow the directions, including the method of application. This is the best way to ensure the product will safely kill pathogens that cause human illness.

A disinfectant product’s safety and effectiveness may change based on how you use it. If a disinfectant product's label doesn't include disinfection directions for a certain method of application, EPA has not reviewed any data on whether the product is safe and effective when used in this way.

EPA's regulatory process ensures that all registered disinfectant products legally sold in the United States include directions for use which, if followed, will allow a product to carry out its intended function without resulting in unreasonable adverse effects on the environment.

Before using a product, always read its label and follow its instructions, including the application method.
