If you’re like me, you have probably wondered at one time or another if it’s safe to mix bleach and Borax together.

I mean, they are both cleaning products, so it seems like they would work well together, right?

You can definitely mix bleach and borax together. When these two substances are combined, they can work even harder to remove the odors and stains on your clothes while deeply whitening them. Since both substances are alkaline, they won’t produce noxious fumes.

It’s important to keep in mind that this doesn’t mean that you should start mixing these two products together willy-nilly.

You should always take care when using bleach, and be sure to follow the instructions on the label.

Read on to learn more about these two substances, and how to safely mix them together.

What Happens When You Mix Borax and Bleach?

When borax is added to bleach, it intensifies the bleach’s effects. This is because borax is an alkaline substance, and it raises the pH level of bleach.

The increased pH level makes chlorine bleach more effective at removing stains and whitening clothes.

In addition, when you mix Borax with bleach, it produces oxygen. This oxygen helps to break down the stains on your clothing, making them much easier to remove.

Now that you know it’s safe to mix these two substances together, you’re probably wondering how to go about doing it. It’s very easy to combine these two products!

The good news is that it’s actually pretty simple. All you need to do is add ½ cup of Borax to your wash cycle along with your regular detergent and bleach.

You can also make a paste out of Borax and bleach, which can be used to pre-treat particularly stubborn stains.

To do this, simply mix together equal parts of Borax and bleach, and apply the paste to the stain. Let it sit for a few minutes before washing as usual.

As always, be sure to exercise caution when using chlorine bleach. Never mix it with other chemicals, and always follow the instructions on the label.

Keep pets and small children away from the area where you’re mixing borax and bleach.

The Benefits of Using Borax and Bleach in Your Laundry

If you’re thinking about adding Borax to your laundry routine, you’re on the right track. This simple change can make a big difference in the way your clothes look and smell.

Here are some of the top benefits of using these two household products:

It Removes Soap Residue From Laundry

If you’ve ever noticed that your clothes don’t seem to be getting as clean as they should be, it might be because of soap residue.

This can happen if you don’t use a good quality detergent, or if you have hard water.

Borax can help to remove this soap residue, leaving your clothes feeling less stiff, softer, and overall cleaner.

It Removes Tough Mold Stains and Odors

Mold stains and odors can be tough to get rid of, but they’re no match for Borax paired with Bleach. These substances are great at eliminating pests, fungi, bacteria, and mold.

Simply add ½ cup of Borax alongside chlorine bleach to your wash cycle, and you’ll notice a big difference.

It Helps With Stain Removal

As you know, bleach is meant for stain removal. However, it’s not always as effective as we would like it to be. This is where Borax comes in.

When you add Borax to your wash cycle, it helps to break down the stains on your clothes, making them much easier to remove.

Just make sure to keep any dark or delicate items out of the wash when you’re using Borax, as it can cause them to fade.

It Makes Your Hard Water Softer

Water is hard because of the minerals that are dissolved in it, such as calcium and magnesium. These minerals can build up on your clothes over time, making them feel stiff and rough.

Borax can help to break down these minerals, making your water softer and your clothes cleaner. This is because it’s a water softener.

You can add it to your laundry routine, or you can use it to pre-treat clothing so that it’s a bit more resistant to hard water.

What Else Can I Safely Mix Chlorine Bleach With?

When it comes to laundry, there are a few other household products that you can mix chlorine bleach with:

Baking Soda

Baking soda is made of sodium bicarbonate, which is a mild alkaline substance. When you mix baking soda with bleach, it produces oxygen.

This oxygen helps to break down the stains on your clothing, making them much easier to remove. Oxygen bleach solutions are also great at removing mold and mildew.


If you’re looking to dilute the strength of your bleach solution, adding water is a great choice. This can help to reduce toxic fumes and make the solution less harsh on your clothing.

This makes it safer to use this powerful cleaning agent around children and pets and can also help to prolong the life of your clothing.

Laundry Detergent

Washing detergent can help to boost the cleaning power of your bleach solution. This is because it contains surfactants, which are chemicals that help to break down dirt and grime.

Simply add a cup of laundry detergent to your bleach solution, and you’ll notice a difference in the way your clothes come out of the wash load.

What is Borax Made Of?

  1. Borax, an alkaline mineral is a sodium salt of boric acid, a separate natural mineral.

    Boric acid can be made from borax by addition of hydrogen.

    Made FROM and made OF are very different statements. They are related but so are water and hydrogen peroxide or baking soda and washing soda.

    Where you’re discussing combining household chemicals for the benefit of non-chemist consumers, generalizations can be unintentionally misleading.
