Can You Use Borax in the Dishwasher?

March 1, 2024

Borax has exceptional cleaning powder and is often used to disinfect, clean, and neutralize odors. It can even be used to soften hard water!

Given that, it’s not surprising to know that it’s great for the kitchen. For example, you can use it to clean the sink, countertops, and floors.

But what about kitchen appliances such as the dishwasher? Can you use Borax to clean those? Let’s find out.

What Is Powdered Borax?

Borax, also known as sodium borate, is an alkaline mineral salt that’s composed of boric oxide, sodium oxide, and water. Appearance-wise, it’s a white powder and dissolves easily in water.

For many decades, it has been used as a household cleaner and has been included in various pesticide products. For example, it can be used to kill ants, mites, spiders, and other insects.


Borax Powder vs Boric Acid

Borax is often confused with boric acid, though the two share many similarities. For one thing, they both contain boron and can be used as a cleaner.

The latter, however, is more processed and refined, making it more powder-like. Borax, on the other hand, is a naturally occurring mineral that’s taken from the earth.

Both chemical substances, however, are toxic to humans and animals and should never be ingested. Contact with human skin can also cause adverse reactions.
