I bought a case of six boxes of this from the manufacturer to get free shipping -- I use about 1/4 cup in my laundry with a little Borax and a TINY bit of laundry detergent. I'm surprised and pleased to find that even my oldest towels smell CLEAN and FRESH where before, even with line-drying outdoors in the sun, they smelled old and kind of sour. Where have they been hiding this stuff? It's great, worth every penny. Very highly recommended!

It's just baking soda on steroids. But unlike baking soda, this stuff is sodium carbonate, which has one atom instead of two, making it harsher than baking soda. So, don't eat it like you can do with baking soda, just clean with it. One thing I have noticed about washing soda as opposed to baking soda is it's much less powdery and dusty compared to baking soda.. That I really like.

I recently discovered the joys of making and having my own laundry soap. Having this substance is essential for that process. It's also good as a non-toxic substitute for making other cleansers and as a laundry additive. It's especially helpful for those of us that live in hard water areas, because it helps to change polarity and keep hard water from staining and causing damage.

I don't know about you guys, but I'm tired of using all those toxic cleansers. I don't even use chlorine bleach anymore.

Those of you on here griping about the price of things when you write a review on a product are off-topic.

I was having trouble with my white towels getting yellow, blotchy stains. For years, I could not figure it out. Nothing worked. Finally... using a 1 to 1 ratio, I mixed one cup of Arm & Hammer Super Washing Soda with one cup of 20 Mule Team Borax. I then added about three tablespoons of this mixture, along with a little bit of my regular detergent, per washing load, and "Voila" my towels were white. They smelled fresh and felt great! This mixture probably neutralized my water enough to release the stains. For a great price, you'll find this at all Walmarts ~~right next to the 20 Mule Team Borax. (I thank my daughter for the terrific idea...I now use it all the time.) My husband is the only one disappointed...he no longer has towels in his rag bag.

We use Washing Soda with our homemade laundry detergent. We started using this about 6 months ago to make it and we LOVE it. Gets our clothes clean, has a light, natural smell and is much cheaper than commercial brand products (depending on where you buy it).

The Washing Soda provides the "cleaning" power of the soap mix. Some people have also mentioned it works sort of like OxyClean -- a detergent booster.

Here is the recipe:

1 bar of fels naptha - grated
1 cup of 20 Mule Team Borax
1 cup of Arm & Hammer Super Washing Soda

If you buy the 55 oz. Washing Soda it will make 6 batches of the homemade detergent (for which you would need 6 bars of fels naptha & 1 76 oz. box of Borax). Making 6 batches is equivalent to about 2 gallons of detergent. We bought an 8.1 quart snap ware container to hold the soap and it works great. It takes probably 30 minutes to an hour to make 6 batches with the biggest factor depending on how long it takes to grate the fels naptha (we have two of us making it -- if you only had one you might have to take more frequent "arm" rest breaks).

We use 1 tbsp. of the mix per laundry load and feel like it does a great job. One of our friends only uses 1/2 tbsp. but we feel like that is really cutting it low.

Unfortunately the Amazon purchase of these products seems to be much higher than several other company's price points. We subsequently found the products cheaper on DrugStore.com (and found an online coupon for $5 off & free shipping!), and the other day notice our local Walmart sells them even cheaper than DrugStore.com. Using the prices at Walmart we can make the detergent for less than $0.05 a load! Using the Drugstore.com prices it was around $0.073 a load and a bit higher with Amazon prices.

Did you know you can make your own washing soda out of baking soda? Just spread it on a baking sheet and heat it up at 400 degrees for 1 hour.

The difference between baking soda and washing soda is water and carbon dioxide. Baking soda's chemical makeup is NaHCO3 (1 sodium, 1 hydrogen, one carbon, and 3 oxygen molecules). Washing soda's chemical makeup is Na2CO3 (2 sodium, 1 carbon, and 3 oxygen molecules). When baking soda is heated up to high temperatures, it breaks down to become washing soda, water steam, and carbon dioxide.

Way over priced. I wasn't finding it in the store at first, but I wasn't looking in the right place. I found it later for less than $3.50/box. After I had ordered it from Amazon. Be diligent and find this in the store you will be better off if you do.

This stuff boosts the cleaning powder of whatever abluent you're using. I use it in laundry, but i also use it in the dishwasher to soften the water, and to clean the shower. It really does a great job on the shower. We live in a hard water area, so tackling hard water is important. It's like borax actually, but it's more related to baking soda. Unlike baking soda, it doesn't have that annoying powdery residue that baking soda has.

Washing Soda is also a key ingredient to making your own laundry soap. I tried making my own laundry soap 4 months ago, and have been hooked on it ever since. Yes, I thought making your own laundry soap was stupid too, until I tried it.

The brick and mortar stores have better prices on this stuff than Amazon does.
