What Is Washing Soda?

Washing soda, also known as sodium carbonate or soda ash, is a powerful natural cleaner. It’s different from baking soda (sodium bicarbonate), even though they start out closely related.

When baking soda is heated, it goes through a chemical reaction that releases carbon dioxide and water molecules. What’s left behind is sodium carbonate, a stronger cleaning agent that works as a water softener and stain fighter.

This chemical compound is often used in:

• Homemade laundry soap
• Dishwasher detergent
• DIY cleaning solutions

It’s a key ingredient in many natural cleaner recipes because it helps break down grease, lift tough stains, and soften hard water.

Why Make Your Own Washing Soda?

There are a few good reasons to make your own washing soda instead of buying it:

• It’s cheaper than store-bought detergents
• It is easier to find baking soda in small town grocery stores
• You control the ingredients in your homemade cleaners
• Helps reduce skin irritations from commercial laundry detergents
• Perfect for sensitive skin households

If you already enjoy making diy recipes like homemade cleaner recipes or your own laundry soap, this is a great next step.

How to Make Homemade Washing Soda

Preheat Your Oven

Set your oven to 400°F. This high heat is necessary to trigger the chemical reaction that turns baking soda into sodium carbonate.

Spread the Baking Soda

Pour your baking soda onto a cookie sheet or baking dish. Spread it into a thin layer so it heats evenly.

Bake

Place the baking sheet in the oven and bake for about 1 hour.

Every 15–20 minutes, use a wooden spoon to stir it around. This helps all the baking soda convert evenly.

Let It Cook

Once done, remove it from the oven and let it cool completely. You’ll notice the texture is slightly different—more grainy and dull.

That means your sodium bicarbonate has transformed into sodium carbonate.

Store Properly

Transfer your homemade washing soda into an airtight container or gallon jar. Store it in a dry place in your laundry room.

How to Use Washing Soda

Now that you have your own washing soda, here are some easy ways to use it.

In Homemade Laundry Detergent

Washing soda is a main ingredient in most homemade laundry soap recipes. It helps clean clothes and soften water.

For a Load of Laundry

Add 1/2 cup of washing soda directly to your washing machine along with your regular detergent.

This boosts cleaning power, especially in hard water.

Homemade Stain Remover

Mix:

• Washing soda
• Hydrogen peroxide
• A little bit of dish soap

Apply to a tough stain before washing.

---

Household Cleaning

Washing soda works great for:

• Soap scum in bathrooms
• Greasy surfaces
• DIY cleaners and purpose cleaners

Just mix with hot water for a strong natural cleaner.

Tips for Best Results

• Always store in an airtight container to keep moisture out
• Use gloves if you have sensitive skin
• Don’t confuse it with baking soda once it’s finished
• Label your container clearly for next time

Washing Soda vs Baking Soda

Even though they start the same, they serve different purposes:

• Baking soda (sodium bicarbonate) is gentle and often used in food or mild cleaning
• Washing soda (sodium carbonate) is stronger and best for laundry and deep cleaning

Both are useful, but washing soda is the better option for heavy-duty cleaning jobs.

Safety and Skin Considerations

Washing soda is safe when used properly, but it is stronger than baking soda. It can cause dryness or irritation for some people.

If you have sensitive skin, consider:

• Using less per load
• Pairing with white vinegar as a fabric softener
