  • Unbeatable Cleaning Power and Essential Household Booster!
Color: Multi Size: 55 Ounce (Pack of 1)
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! ... show more

  • A Laundry Essential I Always Keep Stocked
Color: Multi Size: 55 Ounce (Pack of 1)
I've been using ARM & HAMMER Super Washing Soda for quite a while now, and it's become a staple in my laundry routine. I add it to every single load, and I'm consistently impressed with the results. It boosts my detergent's cleaning power and helps tackle tough stains and odors that regular detergent alone might miss. The fact that I keep reordering says it all - this product delivers. It's especially great for freshening up towels, workout clothes, and anything that needs a little extra cleaning power. The box lasts a good while even with regular use, making it a solid value. If you're looking for something to enhance your laundry routine, I definitely recommend giving this a try. ... show more

  • Wow. Just wow.
Color: Multi Size: 55 Ounce (Pack of 1)
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 ... show more

  • Powerful Cleaner That Saved My Washer and Clothes — Huge Value
Color: Multi Size: 55 Ounce (Pack of 1)
I bought this big box of ARM & HAMMER Super Washing Soda to deep clean my washer, and I’m honestly impressed. I used about 1 cup in an empty hot cycle, and it completely removed the built-up grease and residue that had been getting on my clothes. Since then, no more oily spots or mystery stains — everything comes out fresh and clean again. The box is large and lasts a long time, so it’s a great value for the price. It’s also super versatile for household cleaning, not just laundry. If your washer smells, leaves residue, or your clothes aren’t coming out clean, this stuff works. Highly recommend — simple, effective, and affordable. ... show more
