Diluting bleach

Targeted hygiene is an effective way to clean smarter and help to prevent the spread of harmful bacteria and viruses, including Coronavirus, focussing on disinfecting the surfaces that you and your family most frequently touch.

Research has shown that trying to deep clean your entire home will have little or no impact on combatting the virus – targeted hygiene is much more effective.

When practicing targeted home hygiene, first clean away visible dirt and then apply diluted bleach to the surface to kill germs. When it comes to which surfaces to clean, think about which are those that you and your household touch most often.

These include:                                                                        

  1. Front door handle
  2. Internal door handles
  3. Staircase bannister
  4. Fridge handles
  5. Cupboard handles
  6. Counter tops
  7. Kettle handle
  8. Bathroom taps
  9. Kitchen taps
  10. Toilet flush handle or button

Bleach is proven to kill Coronavirus. I recommend a 1:9 solution of bleach and water when practicing targeted hygiene. That is equivalent to 450ml water and 10 teaspoons of bleach to make 500ml of bleach solution – that’s enough to fill a medium-sized bowl or a spray bottle.

Bleach is a hazardous substance, but when handled carefully, is a powerful cleaning agent against COVID-19.

  • Always check the manufacturer’s label and never use on surfaces other than those directed on the bottle
  • When handling with bleach, always wear household gloves
  • Do not mix bleach with other cleaning products
  • All bleach products or solutions should be kept out of reach of children
  • NEVER ingest bleach


How to dilute bleach safely

Bleach needs to be diluted properly in order to be effective and safe to use as a cleaning solution.

  • Wearing household gloves, place a measuring jug in the sink and mix nine parts cold water to one part bleach – for example 450ml to 50ml (10 teaspoons)
  • Place solution in a labelled container and wearing household gloves use a clean cloth to apply
  • Replace the solution daily
