Do Steam Cleaners Disinfect? Sanitize, Kill Germs & Viruses

One of the oldest known way to kill virus and microbial pathogens is the use of heat.

Early humans discovered this and used fire to make meat edible that would otherwise be spoiled.

Every time we cook in our kitchens, we are using this same principle to keep our food safe for our families.

Is steam cleaning effective for killing viruses and other microbes?

Yes, steam is very effective at killing viruses and other germs and can be used to sanitize your home.

In fact, the Center Of Disease Control And Prevention recommend steam as the preferred method for sterilizing critical medical and surgical instruments that are not damaged by heat [1], and new research from Stanford AIM Lab has highlighted that heat and steam is an effective sanitization method for COVID-19.

If you’re sanitizing to prevent the spread of viruses like COVID-19, follow guidance from the Centers of Disease Control and Prevention (CDC) and your physician, as it overrides any information in this guide –  Make sure that you follow their instructions on how to protect yourself against COVID-19 on their Coronavirus (COVID-19) page but also be aware that steam is a well known and viable way to sanitize.

Moist heat destroys microorganisms by transferring heat through the cell wall causing irreversible denaturation of enzymes and structural proteins [2]. This makes, steam cleaning is an extremely effective but often overlooked proven way [3] to sanitize and disinfect surfaces from viruses.

In fact, industrial steam cleaners exist for cleaning hospitals which are effective alternatives for sanitization in hospitals. They have high efficacy against multi resistant superbugs that have become resistant to all other treatments. We believe that steam cleaning will eventually become more well known as the last remaining weapon against superbugs.

Steam is actually so good that it has even been proven to be just as effective a stopping an outbreak of extremely contagious gastroenteritis as traditional hospital cleaning chemicals in a hospital ward [4].

Do Steam Cleaners Disinfect?

Steam cleaners disinfect and kill 99.9% of germs at a temperature between 175 °F and 212 °F. To kill the most germs, keep them in contact with steam for at least 3 minutes. That’s long enough to get rid of germs, dust mites, mold, and viruses without using chemical sanitizers.

With the dangerous coronavirus COVID-19 spreading rapidly in our community, it is now extremely important to ensure your home is regularly sanitised and disinfected.

Preliminary reports suggest that COVID-19 can survive for up to 2-3 days on some surface

How To Use Steam Mops To Sanitizing Floors

How To Sanitize Benches, Handles, Door Knobs And Other High Touch Areas

Steam must be dry superheated vapor phase steam to kill bugs effectively. It is essential that you do not use steam that is below 212 °F (100°C)

If your steam cleaner is spraying water and not gas like steam, this spray is below 212 °F and you are in danger of spreading the virus, or worse, aerosolizing it into the air around you.

For this reason do not use a small handheld steam cleaner as they often do not meet this requirement. You need a high capacity steam cleaner that emits superheated steam vapor like a canister steam cleaner.

We recommend only using a high quality steam cleaner that is capable of consistently putting out lots of high quality vapor steam above 212 °F.

Only canister style steam cleaners are capable of this because they have larger tanks than handheld steam cleaners and are often designed to emit higher pressure steam for longer durations. The higher the pressure, the hotter the superheated steam will be from the unit.

Be careful to not let the steam pressure decrease too much by steaming for too long. Keep the Steam hot and strong but pausing and letting the pressure build up as you go.

The Benefit Of Using Steam To Clean, Disinfect And Sanitize

There are many reasons why you should steam instead of chemicals. The following are some of the benefits you will enjoy:

  • You can clean almost anything using steam. This includes your bathroom, toilets, floors, carpets, microwaves laundry etc.
  • Steam cleaning doubles up as a way of sanitizing as well as getting rid of bedbugs and fleas.
  • Some chemicals that are used for disinfecting services may be harmful to people who suffer from allergies. Steam cleaning is friendly to people with asthma because it gets rid of dust mites and other allergens on the surface.
  • Cleaning with steam is safe for children and pets.
  • Cleaning with steam is 100% natural. This means that it is also environmentally friendly.
  • Chemical disinfectants an additional budget. Steam canisters use only water which means they are way cheaper than using chemicals.

You can read more about the benefits of using steam mops in an interesting article I recently wrote.

Chemical methods of disinfection and sanitization kill 99.9% of germs just the way a steam mop does. However, why would you use a chemical method when a more natural method is available and can get the same result?

Precautions

You should take some precautions when you want to sanitize your floor using a steam mop. Some people prefer adding chemicals to their steam mops in order to get rid of germs more effectively. In fact, I have seen people adding vinegar in steam mops to get a more powerful cleaning solution.

There are a few problems you’ll encounter when you use this option.

  • Some chemicals will not be friendly to the material of your floor.
  • Adding some chemicals can going clog your machine and cause damage to its parts. Be especially careful not to add corrosive disinfectants in your steam mop.
  • Do not be tempted to overheat the water in the tank in order to kill germs more effectively. This can damage floorings such as those made of hardwood, bamboo, and laminate.

It is recommended that you use the right temperature as indicated by the manufacturer of the steam mop you are using. This is the right way to get the best out of the machine.

Something you should remember is that not all steam cleaners are made the same. Some of them will do a better job of killing germs than others. So, what is the best steam cleaner for disinfecting?

 

FAQ

How do I disinfect with steam?

Most germs are very resilient. Applying steam for a short period may not get rid of them. For this reason, you must plug in your steam mop and allow it enough time to heat up to the right temperature that can kill germs and disinfect your house.

Heat up to the right temperature. Most top-rated steam cleaners produce steam at the temperature of up to 245℉ (118.333 ℃). This is hot enough to kill 99.9% of viruses, germs, dust mites, and even allergens.

Expose germs to hot water vapor for 3 minutes. This ensures even the toughest of the germs get denatured by the high temperatures. This way, you’ll disinfect the floor and get rid of most germs, allergens, mildew, and viruses. Steam also kills fleas and bedbugs on carpets and floors.

How hot should steam be to disinfect?

In order to get the best out of your steam mop or cleaner, you have to ensure that you heat water to boiling point before you start sanitizing your house.

Try to achieve a minimum of 212 °F for the most effective cleaning and sanitization. Most residential steam mops such as Shark, Bissell and HAAN models will heat water up to the temperature of up to 300 degrees Fahrenheit.

Ensure that you are getting enough heat of at least 212 degrees Fahrenheit (100 ℃). This way, you will kill microbes such as Staph, salmonella, and E. coli that are very notorious at causing diseases.

High temperatures will be capable of loosening in grime, most types of dirt and oils that are stuck on the surface. The cleaning process will get rid of mold, mildew, germs, and allergens to leave your floor disinfected.

Note that for you to get the best results, you have to use a steam mop at the right temperature. Just because you’re getting steam out of the jet doesn’t mean it will disinfect your floor. You have to heat the water to a recommended temperature so that it can kill germs and bacteria effectively.

Steam Mop vs Chemicals for Sanitization

Perhaps you’re wondering whether to choose steam cleaning or just go with chemicals to kill germs and disinfect your floor. Harsh chemicals are exactly what they are – harsh – but they still get the job done.

The problem today is that cleaning gets rid of germs but if you use chemicals you introduce another problem on the surface. For us who have kids and pets especially crawling ones, you’ll likely harm them when you use chemicals to sanitize and disinfect your floor.
