DIY Laundry Soap

Looking at Pinterest makes me want to make things.  And since my beloved Purex 3-in-1 complete laundry sheets are going the way of the Dodo, I decided to try my hand at making some laundry powder.  

The most popular recipe around Pinterest is an old-timey one.  Just three ingredients, bar laundry soap, a box of borax and a box of washing soda (not baking soda.) I used three bars of Fels-Naptha, but I already had one grated into the bucket.

This was ridiculously easy and really inexpensive.  It took all of 20 minutes including clean up.  I tossed the bars of soap in the blender with some of the washing soda then tipped all of into a bucket.  Mixed it all together with an old wooden spoon and then transferred it into containers.

The cost for the items to make this laundry soap was $17.14 at my local Kroger and based on volume it made up 156 ounces of powder. Two tablespoons per load of laundry and the per load cost breaks down to just over 11cents per load.  That's half the cost over my Purex sheets when I could get them on a good sale, half the cost of Seventh Generation eco-friendly powder, and a third of the cost of Tide powder.

How does it work?  Really well!  It has a bit of a clean, citrus scent from the Fels-Naptha but no heavy perfumes. It made even Rob's stinky socks and Tally's muddy towels clean and fresh.  The small time investment was definitely worth it.  Another successful Pinterest project completed!


  1. Interesting - have been wanting to try this for awhile. I add borax to my laundry sometimes (stinky teen running clothes) but always with some Tide. I am such a scent-hound that I thought homemade wouldn't have any kind of a clean, fresh scent, so it's good to hear the Fels Naptha adds a little bit. For some reason, totally unscented is disappointing, although more natural.

  2. Interesting…what kind of washer do you have. I haven't done this yet, because I have an HE and didn't know if that mattered. Love your blog BTW, so upbeat. :)

  3. Melva, I have front loading HE washer. And thanks for reading!

    Belle, if you love scent, you may need a booster. I use the Purex crystals in some loads where I want more scent. The homemade soap smells clean but not perfumed, if that makes sense.

  4. I'm so glad I found this post! I've had the makings for this same detergent on top of my fridge for a month and was wondering if it would really work. So glad you posted that it works... I have a new task for tomorrow!
