How to Make Washing Soda

Washing soda is a versatile cleaning agent that can be used for a variety of household tasks. It’s also known as sodium carbonate, and it’s a key ingredient in many laundry detergents and cleaning products. Fortunately, making your washing soda is easy and affordable. In this article, we’ll show you how to make washing soda at home using baking soda.

What is Washing Soda?

Washing soda is a chemical compound that’s made from salt and limestone. It’s also known as soda ash, and it’s an alkaline substance that has a pH of 11. This high pH makes it an excellent cleaner and stain remover. It’s commonly used in laundry detergents, dish soaps, and other household cleaners. You can also use it as a water softener and to unclog drains.

What You’ll Need

To make washing soda, you’ll need the following:

  • Baking soda
  • Oven
  • Baking dish
  • Airtight container


Here’s how to make washing soda:

  1. Preheat your oven to 400°F.
  2. Pour a layer of baking soda into a baking dish. You’ll want to use enough baking soda to fill the dish about 1 inch deep.
  3. Bake the baking soda for about an hour, stirring every 15 minutes. During the baking process, the baking soda will begin to break down and release carbon dioxide, which will turn it into washing soda.
  4. Once the baking soda has turned into washing soda, remove it from the oven and let it cool.
  5. Transfer the washing soda to an airtight container for storage.

Safety Precautions

When making washing soda, it’s important to take the necessary safety precautions. Here are a few things to keep in mind:

  • Wear gloves and safety glasses to protect your hands and eyes from the washing soda.
  • Avoid breathing in the fumes that are released during the baking process. Make sure your kitchen is well-ventilated.
  • Don’t use aluminum baking dishes, as they can react with the washing soda and produce harmful fumes.

Uses for Washing Soda

Now that you know how to make washing soda, you can use it for a variety of household tasks. Here are a few ideas:

  • Add a scoop of washing soda to your laundry to boost the cleaning power of your detergent.
  • Mix washing soda with water to create a paste, and use it to scrub away tough stains on surfaces like countertops and sinks.
  • Use washing soda as a water softener by adding it to your dishwasher or washing machine.
  • Mix washing soda with vinegar to create a powerful drain cleaner that can unclog even the toughest clogs.
