    • 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

    • Great performing laundry additive
Color: Multi Size: 55 Ounce (Pack of 1)
The product works great on my laundry. I've used it on bed sheets, blankets, comforters, and towels. I've also used it on the dogs laundry - washable pee pads, crate pads, dog bed covers & and towels for drying them after they swim. Routine mixed loads of every day clothes - jeans, t-shirts, etc have also been washed with it. I use Persil liquid laundry detergent and Bounce Mega Sheets routinely. The addition of the Arm & Hammer freshens the entire load leaving a clean fresh scent. The box is SMALL! ... show more

This is a great way to give cheaper detergent a little boost. It cleans very well and can be used for everything from laundry to household chores. You only need a couple tablespoons added to your wash and clothes come out super clean.

    • Favorite Laundry Find!
Color: Multi Size: 55 Ounce (Pack of 2)
This is hands down my favorite laundry find! It is so affordable and works just as it says it will, by boosting the efficiency of my laundry detergent. I use it for towels, bedding and clothes that are especially stinky. I have used it in cold, warm and hot water and it works well for me in all of them. There is no scent to this. I use it for every other load or as needed. It's a fantastic product and I have told many people about it! ... show more
