Homemade Laundry Soap

I’ve been making laundry soap for about a year now and am still loving it! It is so easy and quick to make- and the best part is IT’S CHEAP! You will need:
Washing Soda
Baking Soda
Fels Naptha soap bars

I found all of the ingredients at WalMart in the Laundry section.  I don’t remember the prices of everything since I bought it a year ago, but I know I didn’t spend more than $15 on everything.

The recipe that I have been using is as follows:

2 Cups Borax
2 Cups Washing Soda
1 bar finely grated Fels Naptha
1/2 Cup Baking Soda

Cut the soap bar into pieces and add to your food processor along with some of the borax (it helps grate the soap bar). It takes a couple minutes to get the particle size you need. You want it to be grated very finely especially if you wash your clothes in cold water, since it will take longer to dissolve.


If you don’t have a food processor you can use a hand grater (this takes forever though) or you can put the bar of soap in the microwave. It will expand in the microwave and bubble, it usually takes a couple minutes. Once the bar has cooled again it essentially just falls apart when you handle it. This is how I did it before I got a food processor and it works very well but your microwave will smell like the soap for a while….

So back to the food processor method. This is what it will look like when it’s all grated nice and finely:


Pour this mixture along with the remaining ingredients into a large container with a lid. Shake it all up and you’re done! I use one of those plastic containers that is meant for cereal and an old protein powder scooper to measure how much I need.


You only need a tablespoon or two for a load of laundry.

Like I said I have been using this for about a year now and it cleans laundry just like the store bought stuff. I have heard people having problems with it who have a front load washer, they say it left residue somewhere… I have a normal old washing machine and I haven’t noticed any residue on my clothes or in my machine.

Before the baby comes I plan to make a whole bunch of this stuff!

      It’s a Hamilton beach one. From Target. I haven’t used it all that often besides to make the soap, but it has the chopping and slicing blade things along with the beater things (lol I don’t know the proper terms) my husband got me a kitchenaid with a food processor attachment so I use that mostly for cooking cause the clean up is easier 💁
