Indoor Cleaning and Disenfection with Bio-Shield®

Bio-Shield Virus Disenfection

Bio-Shield ®  can be used indoors on hard surfaces as a steriliser and sanitiser.

Research is indicating the SARS /CoV-2 virus can survive for up to 3 days on hard surfaces such as plastic and stainless steel.

The active ingredient in Bio-Shield  -  Quaternary Ammonium, is proven effective and recommended by EPA, for killing viruses on these hard surfaces.

How to use Bio-Shield to sanitise and sterilise interior surfaces

We suggest making up a 1:40 solution = 25ml Bio-Shield Concentrate to 1000ml water.

This can be applied with a spray bottle, or wiped on with a clean cloth (use gloves)


Apply the Bio-Shield to;

  • Door handles
  • Light switches
  • Window handles
  • Bathroom/kitchen/laundry taps
  • Toilet bowls and cisterns
  • Bathroom sinks, baths and showers
  • Fridge/freezer door handles
  • Control panels on washing machines/dryers/dishwashers/microwaves/stoves/ovens/range hoods
    Remote controls
  • Kitchen benches
  • Tables
  • Desks
  • Hard back chairs
  • Soak used cutlery, crockery and utensils for 10 minutes then wash normally
  • Soiled laundry – soak 10 minutes then wash normally


Reapply every 3 to 4 days to maintain the effectiveness.

Please note; Bio-Shield has not been specifically tested on SARS or CoV-2, and we make no claim that it will be 100 % effective. The suggestion for use as an interior sanitiser is based on commonly available data and recommendations from the EPA and CDC for disinfection with Quaternary Ammonium compounds
