Unbeatable Cleaning Power and Essential Household Booster!
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.
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

Versatile Washing Soda Great for Ceramics and Household Use
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.

Great laundry booster
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!

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

It's so worth it!
When I use this..this, STUFF! Along with, Borax and dish detergent, I get the best Grease cutter that I have had the pleasure of ever using in my entire life, and at Sixty-two, that's saying a lot. I have always been a tidy person who's always cleaning and wiping something down. Honestly I don't know why this stuff is not a big deal, I've never come across anything like it, and it's been around for over a hundred and twenty years. It can be used in nearly any cleaning application you can think of and I've never used a half of a cup that you're instructed to use. I have not seen any need for that. When I wash dishes and that's every day I use One TBSP of this stuff, and one TBSP of Borax and a generous squirt of dish soap. This combination leaves your dishes squeaky clean, and grease free with a beautiful shine and rinsing is a breeze, and if you wanted to you could even rinse in cold water it doesn't matter because this stuff obliterates Grease, it literally obliterates it. There 8was grease on the side of the sink one time and I took hot water and I sprayed it, it was still there. So I took a handful of my dish water and I just threw it on the grease, it was gone, I mean it just obliterated it, it's amazing. This is not hype, I'm not lying, and I'm not getting paid or compensated in any way shape or form. This is my experience, and I'm always impressed and saying Wow. I never wear gloves and my hands don't get dried out. But that could be because of the amount I use. I've never used the suggested amount as I've said before there's no need for it. I highly and profusely recommend this product and at five and a half bucks, so worth it. FYI The only reason I didn't give this, Stuff, Super soda washing powder, a five star rating is because giving it a five star would mean it's perfect and there's nothing perfect on this earth even though it does really deserve it.

Arm & Hammer Washing soda
I've been buying this product for years it makes my laundry even whiter it helps my detergent go further it makes it so everything that I'm allergic to it helps me. It doesn't really have much of a scent it's its own natural scent it's not really something I can describe too well it does not hurt my skin as I said I suffer from severe allergies so laundry soaps and just soaps. In general anything touching my skin dies from fabrics so normally I can only wear white with the washing soda it helps me I don't know somehow protective barrier so I'm able to wear certain other fabrics with color in them so it's always a treat. I'm a hammer super Washing soda you can put it also a little scoop of it and if you wash your dishes by hand it helps your dishes be more clean at least that I noticed it's almost like putting them in the dishwasher so there's so many different ways I found using this cleaning my floors it helps my floors even cleaner just so many different things so absolutely I think everybody should be purchasing the stuff I've been doing it for years I was something my grandmother showed me.

Definitely Boosts Laundry Cleaning Power, Has Many Uses Around the House
I was skeptical that this was any better than using regular detergent alone, but it really does boost cleaning of laundry. I washed my workout clothes in the washing machine as always, then I put them in the bathtub with the recommended amount of this washing soda and regular laundry soap, and wow - I wish I had recorded the water - it was gross. So much more dirt came out of my clothes with this added. My clothes felt super soft and the powder has very little scent. I have used it to clean pots and pans as well. I like that it only has natural ingredients, so it is more environmentally friendly than most detergents. It is super easy to use and seems safe on all fabric.
