How to Use Washing Soda in Laundry

Washing soda, also known as sodium carbonate, is a highly alkaline compound that can be used in laundry to boost the effectiveness of detergent and remove stubborn stains. In this article, we will discuss how to use washing soda in laundry and answer common questions related to its usage.

What is Washing Soda?

Washing soda is a white, odorless powder that is highly alkaline in nature. It is made by heating baking soda, also known as sodium bicarbonate, to high temperatures. This process removes the water and carbon dioxide from baking soda, leaving behind washing soda.

How Does Washing Soda Work in Laundry?

Washing soda works by increasing the pH level of water, making it more alkaline. This helps to break down and dissolve dirt, grease, and other stains that are typically hard to remove with regular detergent alone. Additionally, washing soda can soften hard water, which can make it easier for detergent to work effectively.

How to Use Washing Soda in Laundry

Washing soda can be used in a variety of ways in laundry. Here are some of the most common methods:

Add it to the Wash Cycle

One of the easiest ways to use washing soda is to add it directly to the wash cycle. Simply measure out the desired amount of washing soda (typically 1/2 cup for a regular load) and add it to the drum of the washing machine along with your detergent. Run the cycle as usual.

Create a Pre-Soak Solution

If you have particularly stubborn stains, you may want to create a pre-soak solution using washing soda. To do this, dissolve 1/2 cup of washing soda in a gallon of warm water. Soak your clothes in this solution for at least 30 minutes before washing as usual.

Washing soda can also be used as a booster for your regular detergent. Simply add 1/2 cup of washing soda to your detergent during the wash cycle to boost its cleaning power.

Precautions When Using Washing Soda

While washing soda can be highly effective in removing stains and boosting detergent, it is important to use it with caution. Here are some precautions to keep in mind:

Avoid Using on Delicate Fabrics

Washing soda is highly alkaline, which means it can be harsh on delicate fabrics. Avoid using it on silk, wool, or other delicate fabrics that could be damaged by the alkaline solution.

Wear Gloves

Washing soda can be irritating to the skin, so it is recommended to wear gloves when handling it.

Store it Safely

Washing soda should be stored in a cool, dry place away from children and pets. It can be harmful if ingested, so be sure to keep it out of reach.


Washing soda can be a highly effective tool for boosting the cleaning power of your laundry detergent and removing stubborn stains. By following the precautions listed above and using it correctly, you can achieve cleaner, fresher-smelling clothes with ease.
