Adding a disinfection step as part of your daily cleaning routine will help prevent infections.

Route of infection of the new coronavirus

The route of transmission of the new coronavirus is thought to be through droplet and contact transmission from an infected person, with or without symptoms. Therefore, in addition to basic measures against infectious diseases such as cough etiquette and hand washing, it is important to clean and disinfect daily to reduce the risk of infection from areas where droplets of infected people may be present.

Why wiping is effective

As a preventive measure against new coronavirus infection, it is thought to be effective to prevent contact infection by cleaning and disinfecting the areas that people who are supposed to be exposed to droplets often touch by wiping them clean.

Daily cleaning removes normal dirt (e.g., organic matter), followed by consistent disinfection work to bring out its medicinal effects.

Incidentally, the disinfection using a sprayer, which is often envisioned by many people, is not recommended for the following reasons: when comparing the size of the virus to the size of the sprayer particles, the effectiveness and certainty of the disinfection is questionable; it may create a false sense of security and cause sluggish hand hygiene; and the spraying of drugs indoors using a sprayer is not recommended due to exposure to radiation and safety concerns.

How to disinfect after daily cleaning

The chemicals used are alcohol (ethanol) for disinfection at least 70% of the time or sodium hypochlorite at 500 ppm to 1000 ppm.

Since alcohol is currently hard to come by, sodium hypochlorite can be recommended. The names of the products are Hyther and Milton, which are diluted appropriately according to the concentration of each undiluted solution.

Preparations include goggles to protect the body from the medicinal solution (even those for hay fever), gloves (to protect the fingers), mask, disposable cloth (recommended), bucket, etc.

Since sodium hypochlorite is inactivated when it reacts with wood fibers (e.g., paper pulp), it is preferable to use chemical fibers for towels and wipes.

As a precautionary note, sodium hypochlorite can be dangerous when mixed with other chemical solutions as it releases chlorine gas. Never mix, and ventilate well while working.

Please refer to the operation manual for details.
