    • Dude, this stuff is good!!
Color: Multi Size: 55 Ounce (Pack of 1)
I’ve been using ARM & HAMMER Super Washing Soda for a while now, and it’s honestly become a staple in my home, especially for making my own DIY laundry detergent. If you’re trying to cut down on chemicals, save money, or just have more control over what goes into your laundry, this stuff is a game changer. My go-to recipe is super simple: 2 cups washing soda, 1 cup baking soda, 1 cup grated Zote soap, and 1/4 cup borax. The washing soda is really the powerhouse in this mix. It boosts cleaning performance, helps break down tough odors and leaves clothes feeling genuinely clean, not just “fragrance covered.” I’ve used this blend on everything from everyday clothes to gym wear, and even heavily used household items like towels and bedding, and it handles all of it really well. One thing I really appreciate is how well it softens the water. Living in an area with harder water, I’ve noticed a big difference in how effectively my detergent works when I include this. Clothes come out brighter, fresher, and without that dull residue you sometimes get with store-bought detergents. It’s also super versatile. Beyond laundry, I’ve used it for deep cleaning around the house—like cleaning the kitchen sink and bath tub—and it always delivers. The box lasts a long time too, especially when you’re using it as part of a mix, so it’s very cost-effective. Overall, I highly recommend ARM & HAMMER Super Washing Soda if you’re into DIY cleaning solutions or just want something that actually works without all the extra additives. It’s simple, powerful, and dependable—exactly what you want in a laundry essential. ... 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

    • Good Value And Quality
Color: Multi Size: 55 Ounce (Pack of 1)
I bought this to make DIY powdered laundry detergent. I use equal parts of Epsom salts, baking soda, borax, & washing soda. Can add in a cup of sea salt as well. I use about a quarter cup per extra large load of heavily soiled laundry and it is really good for cleaning and leaving everything free of residue. Also cheaper than purchasing laundry detergent and free from chemicals, fragrance and dyes. No plastic bottles in the land fill. Just my 2 cents! ... 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

    • Versatile Washing Soda Great for Ceramics and Household Use
Color: Multi Size: 55 Ounce (Pack of 1)
I used ARM and HAMMER Super Washing Soda to make magic water for ceramics, and it worked very well for that purpose. It dissolved easily and performed consistently, making it a reliable and affordable material for studio use. I love using magic water instead of slip, seems stronger and way less messy. For ceramics, a simple magic water recipe: Original Magic Water Recipe by Lana Wilson 1 gallon water (Amazon) 3 Tablespoons liquid sodium silicate (Amazon) 1 1/2 teaspoon soda ash (Amazon) This creates a solution that helps join clay pieces and repair cracks effectively. Beyond ceramics, this washing soda is also useful as a household cleaner and laundry booster, which makes it a versatile product to keep on hand. A solid value and dependable quality for both art and home use. ... show more
