Environmental Cleaning and Disinfection Guidelines

What Do I Need To Know?

  • The COVID-19 virus can survive for several days on different surfaces and objects.
  • Frequent cleaning and disinfection is important to prevent spread of the disease.
  • Many common household and commercial disinfectant products will destroy the COVID-19 virus.
  • Some disinfectants will have an eight-digit Drug Identification Number (DIN). These products are approved for use by Health Canada.
  • Household bleach (five per cent sodium hypochlorite) may not have a DIN, but may be used following the instructions below.

What Do I Need To Do?

  • Clean often. Areas visited by people should be kept clean and free from clutter.
  • Commonly touched areas should be cleaned and disinfected twice daily or whenever visibly soiled. This includes light switches, door handles, toilets, taps, hand rails, counter tops, toys, touch screens/mobile devices and keyboards.
  • Clothing and fabric items should be laundered and dried on the highest temperature setting possible. Ensure items are thoroughly dried.

Is There a Difference Between Cleaning and Disinfecting?

  • Cleaning products remove dirt, dust and oils, but don’t always kill germs.
  • Disinfectants are applied after cleaning to destroy germs.
  • Cleaning is required prior to disinfection to remove soil and ensure the effectiveness of disinfection (unless otherwise indicated by manufacturer).
  • Common disinfectants include bleach solutions, quaternary ammonium (QUAT), alcohol (70 per cent) and peroxide. Vinegar, tea tree oil solutions, etc. are not proven to be effective disinfectants.

How Do I Make a Disinfecting Solution?

  • Always read product labels and follow the manufacturer's directions. Do not use expired products.
  • According to Health Canada, a disinfecting solution can be made by mixing one part of bleach into 50 parts of water. For example, 1 teaspoon (5 mL) bleach into 1 cup (250 mL) water. These directions are based on bleach that is 5 per cent sodium hypochlorite.
  • Do not mix soap or other cleaners into the bleach and water solution.
  • Apply the disinfecting solution using a spray bottle or a clean wiping cloth.
  • Always use appropriate PPE for working with bleach, including protective gloves.
  • Food contact surfaces should be rinsed with fresh water after disinfecting.
  • Toys that children may put in their mouths must be thoroughly rinsed after disinfecting.
  • If using disinfectant wipes, the manufacturer's recommended contact time (i.e. how long the surface remains wet) must be met. Disinfectant wipes are not recommended for heavily soiled surfaces.
