III.    Correct Use of Disinfectant Solutions for SARS-COV-2

• Cleaning is an essential first step in any disinfection process
• Mechanical action (brushing or scrubbing) removes and reduces dirt, debris and other organic matter such as blood, secretions and excretions, but does not kill microorganisms.
• Therefore, a chemical disinfectant, such as chlorine or alcohol, should be applied after cleaning to kill any remaining microorganisms.
• COVID-19 is susceptible to disinfectants with proven activity against enveloped viruses. These include:
• Chlorine-based products (e.g., hypochlorite) at 0.1% (1000 ppm) for general environmental disinfection or 0.5% (5000 ppm) for blood and body fluids large spills
• 62 to 71% Ethanol; > 0.5% hydrogen peroxide, quaternary ammonium compounds; and phenolic compounds, if used according to manufacturer's suggestions.
• Other biocidal compounds that are benzalkonium chloride or 0.02% chlorhexidine digluconate can be less effective.
