What is a recommended practice before using an EPA-registered disinfectant?

Before using an EPA-registered disinfectant, it is crucial to inspect surfaces for visible debris. This step is essential because disinfectants are most effective on clean surfaces. If there are any organic materials, such as hair, dirt, or product residue, they can impede the disinfectant's ability to effectively kill pathogens. By ensuring that surfaces are free from visible debris, you improve the disinfectant's potency and ensure a higher standard of sanitation.

Rinsing with cold water or mixing the disinfectant with soap does not enhance the disinfectant's effectiveness and can potentially dilute its action or create harmful interactions. Warming the disinfectant is not a standard practice and could potentially alter its chemical composition, leading to reduced efficacy. Therefore, the focus on inspecting for visible debris directly supports best practices in sanitation and infection control.
