Dive deeper into this topic for a thorough understanding.

What If We Are Out of Soap?

It is muscle memory to put soap in the dispenser whenever we use a dishwasher. You cannot even imagine using a dishwasher without a soap. But what if you run out of dishwasher soap? Will your dishwasher clean the utensils effectively?

The use of soap to clean dishes became widespread in the 20th century. Without a doubt, previous generations survived without using soap. Instead, they improvised their way of cleaning.

But can traditional methods be used in a dishwasher? Stick around to find out.

Can You Run a Dishwasher Without Soap?

Soap acts as a solvent that makes the cleaning process more manageable. Although almost everyone uses soap in a dishwasher, it does not mean cleaning cannot go on if there is no soap.

Hot water alone has proven clean efficiently. You will, however, need to use a rinsing aid so that your utensils are spotless. But what do I do about greasy dishes?

Well, to ensure that the cleaning cycle is completed effectively, you will need to take a few more steps before loading your dishes into a dishwasher.

  • A scrap of the food remains, and rinse the dishes.
  • Soak greasy utensils in hot water for a few minutes. 
  • Use other alternatives, such as liquid or powdered soap, in the dishwasher’s soap cup. 
  • Use a rinsing aid during the rinse cycle.

It is normal to be sceptical about not using soap in your dishwasher. I felt the same way the first time I did my dishes without soap, only to discover that I had been wasting money buying dishwasher detergent.

Is Dishwasher Detergent Necessary?

We are inclined to think that dishwasher detergent is necessary when cleaning detergents. Furthermore, a dishwasher has a dispenser where you put your soap. The truth is that you don’t have to use soap in your dishwasher.

Most foods we consume are soluble. For example, carbohydrates, including starch and sugar, can dissolve in hot water. Emulsified fats are also water-soluble. Cleaning off these foods from your dishes requires only hot water. 

Proteins and animal fats, on the other hand, are not soluble in water. You will need to take extra steps while cleaning such dishes. These other alternatives will be discussed as we go on. 

What Happens If You Don’t Put Soap in the Dishwasher?

Starting the cleaning cycle without soap in the dispenser might seem like a crime. However, cleaning will happen as usual, depending on the state of your utensils. Did you get rid of fats on the plates? Is the water temperature ideal for cleaning? All this will determine if the utensils will be cleaned properly. 

Since you are not using soap, you should ensure you have scrapped all the food particles from the dishes. You can skip this step if your dishwasher has a prewash cycle.

Check the temperature of the water. Since you are not using soap, ensure the dishwasher runs at 150°C. Remember, not all dishes can be used under these high temperatures. Use hand cleaning for the dishes with low-temperature resistance. 

Running a dishwasher without soap will take longer than when soap is included. 

Does Dishwasher Kill Germs Without Soap?

Soap does not kill pathogens or bacteria even when used in plenty. Soap only acts as a solvent for stubborn stains. 

Luckily all modern dishwashers have a sanitization cycle. In this cycle, you must raise the dishwasher’s temperature to 150°C. By the end of the process, I can assure you no pathogen will remain breathing if they do breathe. 

What Can I Use If I Run Out of Dishwasher Soap?

Like in ancient times, people used all sorts of natural ingredients to clean their dishes, as soap was not yet that famous. Lucky for us, there are other cheaper alternatives for soap.

And in the spirit of DIY, you can make your dishwasher soap at home using the many available tutorials. However, for the sake of this guide, I will give you a few alternatives that have been proven to work efficiently. 

A simple recipe to make your DIY dishwasher soap

White Vinegar

Scrap off all the food remains from your dishes before loading them into the dishwasher. Put one cup of vinegar in the soap dispenser and set the dishwasher into the rinse cycle. Ensure the dishwasher has a rinse aid solution in the rinsing cup. Start the dishwasher, and your dishes will be good as new. 

Baking Soda

This is the most affordable alternative for dishwasher detergent. Fill the soap dispenser with baking soda and run the dishwasher normally. 

Citric Acid

Citric acid has proven to work efficiently when cleaning and disinfecting utensils. Fill one of the soap dispensers with citric acid and run the dishwasher in the regular cleaning cycle. 

Liquid Detergent

As a DIY enthusiast, I can’t punt how many times I have made my dishwasher liquid detergent. You require very few readily available ingredients and the no-how. Instead of soap, pour the liquid detergent and run the dishwasher as usual.

What Can You Use Instead of Dishwasher Detergent?

Other than the discussed alternative, you use;

  • Powdered dishwasher detergent
  • Washing soda
  • Or any oxygen boost products.

You should avoid shampoos, body wash, washing machine liquids and all-purpose cleaning agents.

Homemade Dishwasher Detergent

DIY projects can be either good or bad. If you don’t research the type of products you are using to do your project, you might end up causing harm to your family members. To avoid this instance. I will mention the best natural ingredients to make your dishwasher detergent. You will follow this tutorial to create your perfect non-toxic dishwasher detergent.

  • Baking soda
  • Washing soda
  • Citric acid
  • Essential oils. 

Ensure the dishwasher detergent cures for 72 hours before using it in your dishwasher.

Can All Dishwashers Use Liquid Detergent?

All dishwashers can use liquid detergent. However, the detergent must have all the requirements to fit dishwasher use. If a liquid detergent forms studs, the studs can fill the dishwasher and start overflowing. 


As much as we have been made to think we need to use soap in our dishwasher, other alternatives have proven to work over time. 

Ensure that you are using the right ingredients for your family’s safety.
