Borax may be a natural mineral, but it doesn't mean it's green. Borax is sold as a powder in a box, and it is still commonly used for commercial laundry, household cleaning, and as a pest repellant, although not always listed on the label. Borax is toxic to humans. It's also toxic to pets.

What Is Borax?

Borax is a white mineral called sodium borate, sodium tetraborate, or disodium tetraborate. It is a hydrate salt of boric acid. Borax was believed to be the component called "flux" used in ancient Rome to make unbreakable glass in the 1st century AD. Today, most of the world's supply comes from a gigantic open-pit mine in California near a town appropriately named Boron. 

If you're hesitant about using borax for your green cleaning due to health and safety concerns, read on to find safer, greener, and more effective substitutes. Ahead, 12 ways you can switch out borax for another toxic-free ingredient.

    Borax is a laundry booster used to soften hard water, deodorize laundry, and boost the stain-removal abilities of your detergent. But you can do the same by using baking soda as a substitute for borax. Baking soda can brighten and soften clothing and lower the pH of hard water just as borax does, but it's risk-free and non-toxic.

    Want sparkling clean porcelain surfaces? Baking soda (and borax) are mildly abrasive, so go gentle and use a non-abrasive cloth or sponge on porcelain tubs, tiles, and countertops if you want the glossy finish but not the hairline scratches. Make a non-toxic DIY scouring powder or paste of baking soda and water that works just as well or even better than borax.

    Considering that borax is something you don't want touching your food (it can potentially cause vomiting and nausea when ingested), the last place you would want to use it would be to clean the inside of your refrigerator.

    Instead of borax, use a paste of baking soda and water to clean the fridge, and then use a rag or sponge to rinse it off well with water. A multipurpose lemon and lime spray is another recommendation; this mixture uses fresh citrus juices and vinegar.

    Get fiberglass surfaces to gleam by using a simple paste of baking soda and water instead of borax. Let the paste sit on any stains on the fiberglass surface for about 10 to 12 hours, then scrub it with some water and a few drops of sudsy liquid dish detergent. If you want more cleaning power, pour or spray some undiluted white vinegar onto the surface and wipe it around with a soft sponge. Then rinse the entire paste, suds, and vinegar with clean water. The result should be a glossy shine.

    Borax for dinner, anyone? The answer should be a resounding "no," so skip cleaning your dishes and dishwasher with this mineral. Many DIY dishwashing detergent recipes include borax, but stay safer by just using environmentally-friendly dishwashing detergent. To clean your dishwasher, use white vinegar and baking soda to remove mineral deposits and dish detergent residues without the worry of leaving behind any borax residue on your plates, utensils, or cups.

    Cleaning a humidifier is tricky because whatever you use to clean the tank will inevitably make its way out into the air that you breathe. But if you don't clean it, you run the risk of mold and mildew growth. Use hydrogen peroxide or vinegar to clean and deodorize the tank, base, and wick (if it has one) instead of borax.

    The Spruce / Meg MacDonald

    In the UK and EU, borax is no longer sold for household use. Sodium sesquicarbonate, marketed under the name "Borax Substitute," is a non-toxic mineral compound with similar pH to borax, making it ideal for cleaning and laundry. It is more potent than baking soda. You can find it sold online as sodium sesquicarbonate or alkali washing soda in the US. It is also used to make bath salts, shampoos, and soaps.
