In response to SARS-CoV-2, also referred to as the COVID-19 virus, the Centre for Disease Controls (CDC) and World Health Organisation (WHO) have published technical guidance on infection prevention and control (IPC).

Reviews indicate that COVID-19 can survive on durable surfaces for up to 9 days, under certain conditions. However, effective de-activation of the virus can be achieved within 1 minute, using a sodium hypochlorite solution and the following recommended process.

Using our revolutionary soft washing equipment and water-based biodegradable chemicals we can :


Removal of visible debris, dirt and dust


Reduce bacterial contamination to safe levels


Removal of any remaining viruses and fungus. In the case of COVID-19, this process breaks apart the protective fat membrane surrounding the virus, de-activating it.

CIS 1976 regularly work on secure sites, hospitals, care homes, schools and universities; are fully insured and provide full risk assessments and method statements before the commencement of every project.
