Will Dishwashers Kill COVID-19 Best Way to Wash Dishes During Crisis?

COVID-19 Coronavirus is a dangerous disease and it has impacted the lifestyle of people all around the world. This pandemic has affected the living of many people as the cases and the deaths rise each day.

Many industries along with health faced many challenges and therefore they have to take many measures to overcome them. People started using masks, sanitizers and kept themselves quarantine at home. One of the most affected industries was the restaurant industry as they had to face many challenges to provide a safe and healthy environment for their customers and employees.

One of the most asked questions by households and restaurant industry people is “Can my dishwasher kill coronavirus” now to answer this question you need to understand a lot many things but the short answer here is “probably”. Now while answering that question the word kill itself is uncertain we need to replace it with “inactive”. A virus becomes inactive when it is not able to infect, spread, and replicate itself further.

Today we are going to answer the question that is “Will Dishwasher Kill COVID-19?’’ If you have a dishwasher and you want to have properly cleaned dishes and want your dishwasher to activate the virus then read this article as it will be very important for your health and your family.

What is a Virus?

The first thing and most important thing that we need to learn is what is a virus? If you want to learn how to inactive a virus then you need to understand what a virus is.

Viruses are very complex and I am not going to explain everything in detail as I have a basic knowledge about it so I will try to explain things as easily as possible. Virus certainly has three of the most major components that are RNA, proteins, and lipids. As for the RNA, it is simply a sort of payload for the virus or we can also say that it acts as a play load for the virus.

The proteins are capable of doing some of the things like they help the virus to break into a healthy cell. It helps in the replication of the virus. The lipid layer can be explained as a layer of fat that helps to surround the whole package of virus and this is the most important component that we are going to talk about as it is the most vulnerable one too which can help the dishwasher to kill or inactive the coronavirus.

The two main weapons to fight and kill Coronavirus

As we saw earlier, the virus contains three major components and the lipid layer is the most vulnerable piece in the virus.

A lipid outer layer is nothing but another word for fat and this lipid layer(fats) can be broken down using two things: soap and heat.


Everyone has soap at home. Normal soap contains fatty substances which are also known as amphiphiles. These amphiphiles are similar to those that the lipid layer of the virus has.

Soap helps to compete with the bonds that help the virus to stick together the soap dissolves the outer coating of the virus. This helps the virus to break down and due to which all the parts of the virus get separated and this will not allow the virus to infect other cells and the virus will become inactive.


Viruses can only survive in a specific temperature range if the temperature range goes higher then the virus becomes ineffective and inactive.

There is certain evidence and studies that reveal that coronavirus can be inactivated in high heat. It was studied in France that the initial result showed that coronavirus is not great with high heat. For inactivating the low level of virus (mild virus) it is studied that 56 degree Celsius heat can be used for activation. For critical cases of the potentially high level of virus, results suggest that the higher level of heat which is up to 92 degrees Celsius is to be used for complete inactivation of the virus.

Things that you need to do to prepare your Dishwasher for killing Coronavirus

The first thing that needs to be done is to check your soaps and the chemicals that you use.

You can contact the manufacturer of your dishwasher and he will provide you with all the details and if you cannot contact that person you can get information from the internet too. information about the right soap is very necessary.

Another important factor is the water temperature you need to make sure that that water temperature is at the proper level so that your dishwasher can sanitize your dishes. The water temperature is very important and vital that helps you to make sure that your commercial dishwasher is capable of killing coronavirus or not.

The Temperature required for sanitization

If you want to sanitize all your dishes and utensils properly using your dishwasher then the water that you are going to use for the final rinse should reach 165 degrees Fahrenheit.

180 degrees Fahrenheit is the proper temperature that is required for the process of sanitization as it is determined by the National Sanitation Foundation.

There is a standard which is known as NSF / ANSI 3 that requires the commercial dishwashers to be able to eliminate 99.99% of all the microorganisms and bacteria.

The surface of the dash should be able to match 160 degrees Fahrenheit for the time of at least 10 seconds by exposing them to a final rinsing temperature that is 180 degrees Fahrenheit.

If you want your dishwasher to use the water at the highest temperature settings then you must check that the boiler is set to several the highest level, there are many cases where the boiler is set to several levels below the highest. You need to check if a water boiler is set and you need to adjust the settings if needed as you are going to need very hot water for killing the virus.

How can a dishwasher kill coronavirus?

An ordinary dishwasher is the best way to deliver detergent and chemicals that are designed to cut the lipids by using the water at high temperatures.

If you have gathered your soap and chemicals and have set the correct temperature for water then you are ready. one thing that you need to keep in mind is when it comes to moving coronavirus from services that are flat and smooth then you need to know that coronavirus doesn’t do very well on smooth surfaces and it usually prefers surfaces that have wrinkles, pits, etc.

Therefore the soap and chemicals along with hot water will easily help you to break down the outer lipid layer which is a layer of fat of the virus. The hot water will help to remove it from the smooth surfaces and then sit away so that inactivates the virus.

Some safety tips

You need to keep in mind that coronavirus can live on surfaces for up to 72 hours that is 3 days. You can try cleaning and putting all your dishes into the dishwasher and keep them clean and make sure that you put all the used items in the dishwasher after the meal.

Most of the detergents help you to break down the lipid layer but some brands of detergent are tough on grease and they will help you and provide you more assurance that your dishwasher will inactivate the virus.

if you are going to wash your dishes using your hand then make sure that you use gloves and use the hottest water possible with a dishwashing liquid that is specially designed for cutting grease.

You must let the dishes get dried in the dishwasher’s high heat. If you are going to use a cloth or towel to dry the dishes then use a couple of clothes for extra safety or you can also wear gloves and do that so that you do not make any direct contact with the dishes that are newly washed.


Coronavirus is a dangerous disease and taking necessary precautions is very important. If you have a dishwasher at home then you can use the dishwasher to clean the dishes and eliminate or inactivate the coronavirus from them.

All you need to do is take little care of some things like keeping the water temperature high using the right detergent or chemicals and you can use your household and commercial dishwasher to keep your customers, your family, and your employees safe. If you make proper use of your dishwasher it will ensure you that it is a powerful tool for fighting coronavirus. I hope this article was relevant, informative, and understandable for you.
