Where to Buy Borax: Best Places to Find It Online and In Store
Borax costs about five dollars a box and replaces three or four separate cleaning products. It lives in the laundry aisle at most stores, low on the shelf, next to the stain removers and boxed cleaners. Finding it is usually easy. Knowing which box to buy, and how to avoid grabbing boric acid by mistake, is the part that trips people up. This guide covers where to buy borax in person, which online sellers give the best price per pound, what the mineral actually does, and the safety limits worth respecting.

What Borax Does and Who Should Buy It
Borax is a naturally occurring mineral salt, also known as sodium borate, that softens hard water, works as a laundry booster, and cleans surfaces without the fumes of bleach. Its full chemical name is sodium tetraborate decahydrate. Most supply is scraped from dry lake deposits and open-pit mines, including the ones around Death Valley, California, that made the 20 Mule Team name famous in the 1880s when Francis Marion Smith’s Pacific Coast Borax Company hauled it out by wagon.
In a wash cycle it raises pH and binds the calcium and magnesium in hard water, so laundry detergent can lather instead of fighting the minerals. That water softening effect is what people notice first: less dinginess, fewer soap deposits on dark fabrics. It also lifts stains, deodorizes drains, and knocks back mold and fungus on grout. Outside the laundry room the same compound serves as a mild preservative, a flux for soldering and metalwork, and a flame retardant in insulation.
Buy it if you have hard water, want one product covering several household uses, or need a cheap ant treatment for a kitchen trail. Skip it if small children or pets can reach your cleaning cabinet. Boron compounds are not something anyone should swallow.
Features Worth Paying For in Borax
Only three things genuinely differ from one box to the next: purity, granule size, and price per ounce. Everything else on the carton is marketing.
Single-ingredient purity. Pure borax lists sodium tetraborate decahydrate and nothing else. No fragrance, no dye, no surfactant. Blended formulations cannot be used for slime, insect bait, or ceramic glaze work, only for washing.
Granule size. Fine white powder dissolves in warm water in under a minute. Coarse crystals can survive an entire cold cycle intact, which is the complaint buyers raise most often. If you wash cold, dissolve a half cup in hot tap water and pour the borax solution into the drum.
Package size and unit price. The grocery box is cheaper per ounce than the bulk bag, which surprises most people. Pure grade costs more to produce than the retail detergent additive, so buying bigger does not automatically buy cheaper.
| Package | Typical price | Per ounce | Best for |
|---|---|---|---|
| 20 oz box | $3 to $4 | about $0.18 | Occasional stain treatment |
| 65 oz box | $5 to $7 | about $0.09 | Regular household washing |
| 5 lb resealable bag | $12 to $16 | about $0.17 | Slime, crafts, pest work |
| 25 lb sack | $45 to $70 | about $0.14 | Cleaning businesses |
Resealable packaging. This compound pulls moisture from the air and sets into a brick. Cardboard cartons with a tuck flap are the worst offenders. A zip-top bag or screw-lid tub earns its small premium past a couple of pounds.
Label intent. A carton labeled for laundry and a sack labeled as a technical-grade chemical substance hold the same compound. Technical grade often costs less per pound and sits with soap-making supplies, not in a grocery aisle.
What Not to Buy: Common Borax Pitfalls
The most common error is buying the wrong boron compound entirely, and the two products often sit one aisle apart.
Grabbing boric acid instead. Borax and boric acid are related but not interchangeable. Boric acid is a stronger acid registered with the EPA for pesticide uses, sold as roach powder and as an antiseptic. If pests are the goal, read our guide on where to buy boric acid instead.
Trusting the “borax water” trend. Drinking dissolved borax is not an approved internal use and is not a treatment for arthritis or anything else. The National Capital Poison Center has published a plain warning about it, so read their guidance on the claim before believing a video. Exposure to borax matters most for children and pregnant women. Prolonged contact with a concentrated solution can also irritate skin, so wear gloves for long cleaning sessions.
Assuming it is unregulated everywhere. It is not approved as a food additive in the United States or the European Union, and EU chemical rules restrict consumer sale, which is why it is harder to buy in Europe than in the U.S. That is a regulatory difference, not proof the box on the shelf is unsafe used as directed.
Buying a clumped clearance box. Squeeze the carton. If it feels solid rather than shifting like sand, it has absorbed water and you will spend ten minutes breaking it up.
Paying extra for a scented blend. Fragranced formulations cost more per ounce and lock you out of every use except laundry.
Finding Borax Near You: In-Store Options
Walmart
Walmart is the most reliable shelf in the country for this product and usually the cheapest. Check the laundry aisle near the stain removers, on a lower shelf, since the brand rarely pays for eye-level placement. The 65-ounce carton typically runs four to six dollars, with store pickup available if the shelf is bare.
Target
Target shelves it with cleaning supplies rather than liquid laundry products at many stores, so check both aisles. Selection is thinner than Walmart’s and small-format stores frequently skip it. Confirm stock in the app first, then use Drive Up.
Walgreens
Walgreens carries it as a household cleaner, near the dish soaps and multipurpose sprays. Pharmacy chains stock the smallest range at the highest unit price, so treat this as convenience rather than value. The site ships to home when the local store is empty.
Grocery Chains and Warehouse Clubs
Kroger, Price Chopper, and Hannaford shelve it with boxed cleaning products, sometimes in a natural cleaning bay. Costco and Sam’s Club stock it inconsistently, but a club multi-pack beats every other per-ounce price. Independent grocers are the least dependable source.
- Check the laundry aisle first, low shelf, beside stain removers.
- Check the general cleaning aisle second, near the dry cleansers.
- Ask an associate to scan the shelf tag for backroom inventory.
- If the count reads zero, check the chain app for a sister store nearby.
Ordering Borax Online: Where and Why
Amazon
Amazon has the widest range, from the classic carton to resealable bags of pure sodium borate. Prime orders typically land in two days. Read the listing to confirm the grade, and check who ships it, because third-party sellers set their own return rules and powdered chemical substances are often non-returnable once opened.
Retailer and Supplier Websites
Walmart.com, Target.com, and Walgreens.com all sell it with pickup or delivery, and adding it to a larger order is the easiest way to clear a free-shipping threshold on a five-dollar item. Soap and candle suppliers such as Wholesale Supplies Plus list technical-grade sodium borate by the pound. Shipping weight is the hidden cost: freight on a 25-pound sack often exceeds the product’s value.
Alternatives to Borax
Three substitutes cover most of what this mineral does, and one is genuinely better for a specific job.
- Soda ash (washing soda). Sodium carbonate, not a boron compound. It softens water more aggressively and cuts grease better, but it is harsher on wool and silk. For pure hard-water problems, soda ash is the better buy.
- Baking soda. Sodium bicarbonate deodorizes and scrubs, and it is food-safe, which borax is not. It does nothing for water hardness.
- Oxygen bleach. Sodium percarbonate lifts stains and whitens better than a borate does, with no boron in the wastewater.
- Boric acid. The right pick when pests, not laundry, are the actual problem.
Skip the category entirely if you have soft water, since the softening benefit is what justifies the extra scoop. For scale on fixtures and kettles, citric acid works faster, and for oil absorption bentonite clay is the mineral you want.
Borax Products Worth Buying
Picks below are chosen on price per ounce, purity, and how easy each one is to find in stock.
Best overall: 20 Mule Team Borax Natural Laundry Booster, 65 oz. The default American box, made by Henkel, sold nearly everywhere, and the cheapest per ounce of any retail option. Roughly $5 to $7. Check price on Amazon
Best for crafts and slime: Pure Original Ingredients Borax Powder, 5 lb. A resealable bag of single-ingredient powder with no fillers, which is what slime and glaze projects need. Buy it for purity, not savings. Around $12 to $16. See it on Amazon
Best for pest control: Harris Boric Acid Roach Powder with Lure, 16 oz. Named here because shoppers reach for the wrong jar constantly. This is boric acid, not the laundry mineral, and it ships with a built-in bait lure. Around $6 to $10. Check price on Amazon
Best budget: store-brand or technical-grade sodium borate. Grocery private labels and chemical suppliers sell the identical compound for less. Confirm the label reads decahydrate and nothing else. Browse the listings
Start at Walmart, which carries the lowest unit price and the best odds of stock. If that shelf is empty, check Target’s cleaning aisle before ordering, then fall back to Amazon for bulk or pure borax. Buy the 65-ounce carton unless a craft project needs single-ingredient grade, store it sealed and dry, and keep it away from food.
FAQ: Buying Borax
Is borax the same as boric acid?
No. Borax is sodium tetraborate, a salt with the anhydrous formula Na2B4O7, while boric acid is H3BO3. Both contain boron, which is why they turn up in similar product categories, but boric acid is registered as a pesticide with the EPA and this one is sold as a cleaner. They do not substitute one for one in any recipe.
Has borax been banned?
Not in the United States, where it stays on grocery shelves as a laundry and cleaning product. The confusion comes from Europe, where it is classified as a substance of very high concern and restricted for consumer sale, and from the fact that no major regulator approves it as a food additive.
Is borax the same as washing soda or baking soda?
No, and the three get mixed up because all are white powders sold near each other. Washing soda is sodium carbonate, baking soda is sodium bicarbonate, and neither contains boron. Only the borate softens water and inhibits mold at the same time, which is why some homemade recipes call for all three.
Why is it hard to find in some stores now?
Powdered laundry products lost shelf space to liquids and pods over the past decade, so many chains cut the category to one or two facings. Stock gaps are usually distribution, not discontinuation. Supercenters and warehouse clubs hold inventory more consistently than small-format urban stores do.
