Riskiest Surfaces And How To Clean Them

One of the tricky things about the COVID-19 Novel Coronavirus is how it survives on surfaces; which is better than we would like. A recent study published in the New England Journal of Medicine suggested that the viability of the virus depended on various conditions; including the type of surface.

They tested the virus five ways and state that in their trials they determined the virus could last:

  • On Copper for up to 4 hours
  • On Cardboard for up to 24 hours
  • On Stainless Steel and Plastic for up to 3 days.

That means your riskiest surfaces are those made of stainless steel and plastic. So have caution around such materials when out in the world, if you can, disinfect them before and after use. The following will be some of the riskiest items according to the Government of Canada:

  • door handles
  • debit machines
  • toilets
  • phones
  • electronics
  • toys
  • television remotes

The government also provided a list of hard surface disinfectants that are likely to be effective for use against coronavirus (COVID-19). They also suggest you could use diluted bleach prepared in accordance with the instructions on the label, or in a ratio of 1 teaspoon (5 mL) per cup (250 mL) OR  4 teaspoons (20 mL) per litre (1000mL). The CDC suggested that alcohol solutions of at least 70% could be used. Cleaning these surfaces regularly with the products mentioned is recommended.

And if you’re wondering what the fifth way the researchers tested was? That was in the air; where the determined it had the potential to last up to 3 hours. Which is why practicing social distancing is so important. If you go out where contaminated people are, there could be particulates with the virus just floating about hours after they left.

Stay home, stay safe, wash your hands.
