Does a Steam Cleaner Kill Viruses?

With increasing concerns about cleanliness and hygiene, particularly in the wake of global health crises, people are more focused than ever on effective cleaning methods. Steam cleaning has become a popular option, but one question that frequently arises is: Does a steam cleaner kill viruses?

In this blog post, we will dive into the science behind steam cleaning, how it works against viruses, and whether its an effective tool for disinfecting your home or workplace.

What Is a Steam Cleaner?

A steam cleaner is a device that uses hot water vapor to clean surfaces. It works by heating water to a high temperature, producing steam that is then directed at a surface through a nozzle.

The high temperature of the steam helps loosen dirt, grime, and stains, making it easier to clean. Steam cleaners can be used on various surfaces, including carpets, hard floors, upholstery, and even kitchen appliances.

Types of Steam Cleaners

There are several types of steam cleaners available, each suited for different cleaning tasks:

1. Handheld Steam Cleaners: Portable and lightweight, these are ideal for smaller tasks such as cleaning countertops, bathroom tiles, or car interiors.
2. Steam Mops: Primarily designed for cleaning hard floors, steam mops use the power of steam to sanitize and remove grime from surfaces like tile, linoleum, and hardwood.
3. Cylinder Steam Cleaners: These are larger and more powerful, capable of handling multiple surfaces and providing a deeper clean than handheld models.
4. Vapor Steam Cleaners: These models heat water to very high temperatures and produce dry steam, which contains less moisture, making them ideal for delicate surfaces or areas that should not be soaked with water.

How Does Steam Cleaning Work?

Steam cleaners work by producing water vapor that reaches temperatures of up to 200?F (93?C) or higher. This high-temperature steam is effective in cleaning by:

1. Loosening Dirt and Grime: The heat breaks down grease, stains, and dirt from surfaces, making them easier to wipe away.
2. Killing Germs and Bacteria: The heat from the steam can kill many types of harmful microorganisms, including bacteria and viruses, due to the extreme temperature.
3. Disinfecting Surfaces: Steam not only cleans but also disinfects by neutralizing pathogens like mold, bacteria, and potentially viruses.

Can Steam Cleaners Kill Viruses?

The simple answer is yes, steam cleaners can kill many types of viruses. This is because most viruses are not resistant to high temperatures, and the steam produced by a steam cleaner is typically hot enough to inactivate or kill them. However, there are a few important considerations to take into account.

Temperature Is Key

For a steam cleaner to effectively kill viruses, it must produce steam at a high enough temperature. According to health and safety guidelines, most viruses, including the ones responsible for common illnesses like influenza, the common cold, and even certain strains of coronaviruses, can be inactivated at temperatures around 160?F to 212?F (70?C to 100?C).

Steam cleaners typically produce steam that reaches at least 200?F (93?C), which is sufficient to kill or inactivate most viruses. For example, SARS-CoV-2, the virus responsible for COVID-19, is known to be sensitive to heat, and temperatures over 158?F (70?C) can destroy the virus.

Contact Time

The effectiveness of a steam cleaner also depends on the amount of time the steam is in contact with the surface being cleaned. For the steam to kill viruses, it needs to be applied for a sufficient duration. Generally, you need to hold the steam over a surface for 10 to 15 seconds to ensure that the heat has penetrated deeply enough to neutralize the virus.

Surface Material

Not all surfaces respond equally to steam cleaning. Some surfaces, especially porous ones, may trap viruses and make them more difficult to eliminate with steam alone. On hard, non-porous surfaces like countertops, glass, and metal, steam cleaning can be highly effective at killing viruses.

On the other hand, soft materials like upholstery and carpets may require repeated steaming to ensure that viruses are fully neutralized.

Which Viruses Can Steam Cleaning Kill?

Steam cleaning has been found to be effective against many types of viruses, including:

• Influenza (Flu) Viruses: Steam cleaning can kill flu viruses on surfaces by exposing them to high temperatures.
• Common Cold Viruses (Rhinoviruses): Steam is hot enough to kill the rhinovirus, which causes the common cold.
• Norovirus: This virus is known for causing stomach-related illnesses, and steam cleaning can eliminate it from contaminated surfaces.
• Coronavirus: As mentioned earlier, steam cleaning can inactivate coronaviruses, including SARS-CoV-2, by applying steam at temperatures of over 158?F (70?C).

While steam cleaning can kill these and other viruses, its important to follow proper cleaning techniques and use a steam cleaner with a high enough temperature to ensure effective disinfection.
