Disinfectants
Precleaning is essential and arguably the most important step when disinfecting. Microbes & viruses can live beneath the surface of a biofilm and if the biofilm is not removed first, the disinfectants effectiveness can be greatly reduced. Just coming in and spraying the room does not effectively disinfect. A disinfectant MUST be allowed time to dwell on a surface. A products efficacy (kill rate) is much lower if not allowed to dwell. The CDC and product manufacturers recommend a dwell time, which can be up to 10 minutes.
ATP Testing
Adrenosine triphosphate (ATP) is an energy molecule found in all plant, animal and microbial cells. The detection of ATP on a surface therefore indicates the presence of living biological matter. Measuring the amount of bioluminescence from an ATP reaction provides a good indication of surface cleanliness.
