Unbeatable Cleaning Power and Essential Household Booster!

Tugba OncuDecember 2, 2025

ARM & HAMMER Super Washing Soda is an absolute powerhouse and an essential product that every household needs. I use it constantly, primarily as a Laundry Booster to tackle tough stains and improve the performance of my detergent, especially with towels and heavily soiled clothes—it works wonders to brighten and remove lingering odors! But its versatility is what makes it a five-star champion. I also use it to make my own powerful, non-toxic household cleaners, to cut through grease on stove tops, and to clear clogged drains. A little bit goes a very long way, so this large 55oz box lasts forever, making the value for money exceptional. It is pure, natural, and super effective. If you need a reliable, industrial-strength cleaner that’s still safe for laundry and household chores, this is the gold standard. I highly recommend keeping a box of this on hand at all times!

Wow. Just wow.

Pvt I SpyNovember 2, 2025

Texas. Hard water. So hard. Adding this to my laundry routine was insanity. Difference like night and day. I'm not sure how much I'm suppose to be using... But this is the mixture that made my towels and clothes the softest and cleanest they've ever been. 2 boxes borax and 2 boxes super wash soda, mix in a 5 gallon bucket, add lid. Three pumps of Sal Suds, 1/2c to 1 cup scoop of this for my mini washer, 2x2 floor space and 4 foot high, clothes come out soft, less wrinkles and smelling deeply cleaned. Even my decades old favorite shirt finally doesn't smell like me even after one wash. Never going back to detergent. Always used natural things, but no powders in decades due to the residue. This is so different. I even made a paste with the powder and scrubbed the shower doors of the lime scale. Great stuff. Update.. been a few weeks. This stuff is bananas! My kitchen towels are no longer folding like I've added starch right off the line. They've softened. I have maybe 40 flour sack your kitchen towels and 20ish kitchen hand towels, I don't use paper towels, not for decades upon decades, these towels have seen it. But washing them week by week in this stuff, as they rotate they are folding nicer and less 'kitchen' smell? The pasta stains are fading but IDC about stains, just clean and ready to absorb. I'd like to try this mix with vinegar for a few loads, see if that improves anything. If you let the clothes soak in this, but just enough water to cover, for greasy work things, etc.. then wash with the full amount of water, you'll be surprised how clean and supple the clothes come out. I'm gonna wash all my summer bathing wear in this and see if they feel better next summer. I'll update when there's anything now amazing to share Read more

A Must-Have for Every Home!

AndreaAugust 29, 2025

Washing Soda has quickly become one of my favorite cleaning staples. This powerful product is a true workhorse, excelling as both a laundry booster and an all-around household cleaner.In the laundry, it's a game-changer. Adding just half a cup to my loads makes whites brighter, colors more vibrant, and effectively tackles tough stains and odors. It helps my detergent perform better, leaving clothes noticeably cleaner and fresher.But its utility doesn't stop there! I regularly use Washing Soda for:Sparkling Floors: A great solution for cutting through grime on tile and linoleum.Degreasing Kitchens: Perfect for stubborn stovetop grease.Refreshing Outdoor Furniture: Tackles dirt and mildew with ease.What I love most is its natural, phosphate-free formula, making it an eco-conscious choice. Plus, it's incredibly economical – a single box lasts a long time, delivering excellent value.Just remember to dissolve it in warm water first and wear gloves if you have sensitive skin.The Verdict: ARM & HAMMER Super Washing Soda is an indispensable, affordable, and highly effective solution for countless cleaning tasks. If you want brighter laundry and a cleaner home, you absolutely need this in your arsenal. Highly recommended! Read more

Great laundry booster

HelenaDecember 27, 2025

Bought on a recommendation from a friend. Spend a lot of time fishing and trying to get fish and bait smell out of clothes was very difficult. Was told to use this as a booster in the wash; it worked great! Fish smells gone! I use it in every load now. No more leftover smells! Read more

Arm & Hammer Washing Soda is an old product that works better than some new laundry additives.

TrishDecember 26, 2025

Arm & Hammer Super Washing Soap is actually getting my clothes cleaner. It leaves no scent or any soapy buildup on fabrics. I think my sheets are softer. My towels are softer and more absorbent, too. My whites ARE whiter, and the colors aren’t fading. I’ve noticed that oily stains are coming out with no extra scrubbing needed. Who would’ve thought that my grandmother was right?! Read more
