Does borax sanitize laundry? The ultimate cleaning solution

Borax has been used for decades as a powerful cleaning agent for laundry. It’s a potent, all-natural mineral that can handle almost any stain or odor. But what about sanitizing? Can borax actually sanitize laundry? In this article, we will take a closer look at borax and its properties to see if it’s a viable solution for sanitizing laundry.

What is Borax?

Borax, also known as sodium borate, is a naturally occurring mineral that has been used for cleaning and laundry purposes for many years. It is composed of boron, sodium, oxygen, and water, and it has a white, powdery appearance. Borax is commonly used as a laundry booster, stain remover, and household cleaner because of its incredible cleaning and deodorizing properties.

How Does Borax Work?

Borax works by changing the pH level of water, making it more alkaline. This change in pH level helps to break down stains and dirt, making it easier to remove them from fabric. It also has a mild disinfectant effect, which can help to kill bacteria, fungus, and other microorganisms that may be present in your laundry.

Can Borax Sanitize Laundry?

The short answer is yes, borax can help to sanitize laundry. As mentioned earlier, borax has a mild disinfectant effect that can help to kill bacteria and other microorganisms. However, it’s important to note that borax isn’t a sterilizing agent, which means it won’t kill all types of bacteria and viruses.

If you’re looking for a more potent sanitizing solution, you may want to consider adding bleach or hydrogen peroxide to your laundry. These substances are much more effective at killing germs and can be used alongside borax for even better results.

How to Use Borax for Sanitizing Laundry?

If you decide to use borax to sanitize your laundry, it’s important to use it correctly to get the best results. Here’s a step-by-step guide:

  • Start by filling your washing machine with warm water.
  • Add your normal laundry detergent along with 1/2 cup of borax.
  • For heavily soiled or smelly laundry, use 1 cup of borax instead.
  • Place your laundry in the washing machine and run a cycle as you normally would.
  • For even more sanitizing power, consider using a hot water cycle instead of warm.

Borax vs Other Sanitizing Agents

While borax can help to sanitize your laundry, it’s not the only solution out there. Let’s take a look at how borax compares to other common sanitizing agents:

Sanitizing Agent Pros Cons
Borax Effective at killing bacteria and other microorganisms, all-natural, inexpensive Not a sterilizing agent, not as effective as bleach or hydrogen peroxide
Bleach Fast-acting, potent, kills a wide range of germs and bacteria Can be damaging to some fabrics, must be used carefully to avoid discoloration, strong odor
Hydrogen Peroxide Effective at killing bacteria and viruses, natural alternative to bleach, no harsh fumes May not be as effective as bleach for certain types of germs, can be damaging to some fabrics


Borax can be a helpful and cost-effective solution for sanitizing your laundry. While it may not be as powerful as other sanitizing agents like bleach or hydrogen peroxide, it is a natural and versatile option that can get the job done in most cases. If you’re looking for a more potent sanitizing solution, consider using borax alongside bleach or hydrogen peroxide for even better results.
