Clear carefully chooses chemistry based on client profile and the threat to be addressed.  For CoViD 19, our leadership team selected Medentech’s Klorsept (*1) for both its safety profile (NFPA rating 0,0,0) as well as its relatively brief required dwell time of 1 minute (*2) for virus deactivation (kill).

Our services are performed using air-assisted electrostatic applicators (*3) to ensure proper coverage. As with all disinfectants and chemicals we apply, Clear closely follows the manufacturer’s required concentration and protocol for CoViD 19 (4306 ppm, Hepatitis A virus; Coxsackievirus B3).

 As an added measure of health and safety, the Grace Preschool facilities are protected quarterly with Goldshield GS 75 (*4).  Goldshield kills germs, bacteria and mold on contact and provides a residual protectant that lasts for up to 90 days.

Clear has been providing professional disinfection services within the private, commercial, educational, and government sectors since 2015. For questions or more information, please contact us: (443) 561-9100 or
