If you’re looking to cut back on harsh chemicals at home, you’re not alone. More and more people are turning to homemade cleaning solutions as gentler, greener alternatives to store-bought sprays. While vinegar-based mixtures have long been a favorite, there’s another natural ingredient that deserves a spot in your cleaning caddy: borax.

Borax, or sodium borate, is a naturally occurring mineral salt composed of sodium, boron, oxygen, and water. You’ll often spot it in the laundry aisle, thanks to its stain-fighting powers, but it’s just as effective as an all-purpose cleaner. When mixed with warm water, borax becomes a powerful solution for cleaning countertops, appliances, and even floors.

Why borax works so well

Borax stands out because of its alkaline nature. It has a pH of 9.5, which helps it break down fats, oils, and acidic residues with ease. But it doesn’t stop there. Borax also has natural antibacterial and antifungal properties, making it great for tackling mold, mildew, and surface germs.

In addition to cleaning, borax is an excellent deodorizer. It neutralizes acidic smells like pet urine, old food, smoke, or that musty odor you just can’t seem to get rid of. And while it’s powerful, borax is still gentler than many conventional cleaners. Used correctly, it won’t give off fumes and doesn’t carry a strong odor. That said, because it can still irritate the skin, eyes, or throat with extended exposure, it’s best to wear gloves and ensure the space is well-ventilated while you clean.

One important caution: borax should never be ingested, and it can be harmful to kids or pets if consumed. Make sure to store it safely out of reach when not in use.

How to make your own borax cleaning spray

Creating a borax-based spray is simple and cost-effective. Start with this basic recipe:

• 2 tablespoons of borax
• 2 cups of hot water

Add both ingredients to a spray bottle and shake until the powder dissolves completely. The hot water helps break down the borax more easily.

For a bit of extra grease-fighting power, you can enhance the formula by adding:

• 1/4 cup white vinegar
• A few drops of your favorite essential oil (optional, for scent)

Shake again to combine. Once mixed, this spray is ready to use on most non-porous surfaces in your kitchen and beyond.

Where to use (and where to avoid) your borax spray

This DIY cleaner is a great go-to for:

• Kitchen and bathroom countertops
• Appliance surfaces
• Tile or linoleum flooring
• Wall marks from pens or pencils

Just be mindful that borax isn’t suited for every material.

Surfaces and materials you should never clean with borax

Despite its many perks, borax isn’t suitable for every cleaning task. In fact, it can damage some common household items. Here are nine things you should avoid cleaning with borax:

1. Azo-dyed rugs, curtains, and upholstery

Borax’s high pH level can break down azo dyes, causing irreversible fading and discoloration. If your fabrics are brightly colored or don’t list borax-safe materials like olefin, skip it.

2. Silk, wool, and other protein-based fabrics

While borax is often used as a laundry booster, it can degrade delicate natural fibers like silk and wool. Always check care labels before using any high-alkaline cleaner.

3. Dishes and cookware

Borax is toxic when ingested, even in small amounts; just 5 grams can be harmful to children. If any residue is left behind, it could contaminate your food. Opt for safer alternatives like baking soda instead.

4. Baby and children’s toys

Young kids often put toys in their mouths, making borax a poor choice for cleaning them. Its toxicity and lack of disinfecting power make diluted bleach or unscented detergent better options.

5. Pet bowls and toys

Pets are just as vulnerable to borax poisoning as humans. Ingesting even small amounts can cause gastrointestinal distress or worse. Wash their dishes with hot, soapy water instead.

6. Houseplants and foliage

While borax can kill mold, it can also kill your plants. It’s a natural herbicide and desiccant, so steer clear of using it near anything green and growing.

7. Stone countertops

Marble, granite, and other natural stones can be damaged by borax’s alkalinity. It can dull their finish, cause etching, and compromise the sealant over time.

8. Luxury flooring materials

Like countertops, natural stone flooring doesn’t respond well to alkaline or acidic cleaners. Regular sweeping and stone-safe commercial products are better long-term solutions.

9. Pest control in pet-occupied areas

Borax is often used in DIY pest control, but if pets roam the area, it’s risky. Even small amounts can be toxic if ingested or inhaled. Try food-grade diatomaceous earth instead.

A careful clean

Borax may not have the same trendy reputation as vinegar or baking soda, but it’s a cleaning powerhouse that, when used correctly, can be a great addition to your cleaning toolkit. Its odor-neutralizing, degreasing, and antibacterial properties make it a reliable all-purpose spray for many surfaces. Safe (when used wisely), versatile, and affordable, this natural mineral can elevate your everyday cleaning routine. So grab your gloves, mix up a bottle, and let borax do its thing.
