Making your own laundry detergent is a super simple way to get clean clothes at a fraction of the price as storebought. Even better, you’re cutting down on packaging waste by not purchasing new bottles/boxes every few months.

Does Homemade Laundry Detergent Really Work?

Yes! It works great and it is effective and super affordable. We have used this in traditional top loader washers as well as a HE washer. I will say that it works best in warm water, especially if using a HE washing machine.

Homemade Laundry Soap Supplies

You’ll need:

  • Super Washing Soda
  • Baking Soda
  • Borax (only about $5 in the laundry aisle of major stores)
  • Bar soap
  • {optional} essential oils
  • Mixing bowl
  • Measuring cups
  • Cheese grater
  • Spoon
  • Storage container

Various recipes suggest using Fels Nelpha soap, but I cannot stand the smell of it! We use whatever bar soap we have hanging around. Use a brand that you already know is sensitive enough for your family’s skin.

The dryer is often the number two user of electricity in American homes. For extra money and energy savings, we love to line dry our laundry outside whenever possible (we have this great retractable clothesline) and use these drying racks when the weather does not cooperate. Check out all my tips for line-drying laundry.

Pro Tips

  • If you want to make a bulk batch, I find using the grating attachment on my food processor makes super quick work of it.
  • Using warm water is best to help dissolve the grated soap.
  • If you want to use essential oils, use 30 drops of your favorite scent.

  1. Mommy of monkeys, yes, I just throw it in a big plastic container and shake it up. No water, no boiling. There are recipes out there for liquid detergent, but they take too long to satisfy my instant gratification personality.

  2. Do you just mix all the ingredients together? No water, no boiling? Just mix and add to laundry?5 stars

  3. Cookie, yes I’m very happy with the Dr.B’s! I also used to use Fels Nelpha, but my husband complained that it smelled like an “old folks home”. LOL

    We wash all our clothes in cold, so this hasn’t been an issue.

  4. I have made homemade laundry detergent for some time now. I was using Fels-Naptha for my soap component originally but switched to Zote when I accidentally let myself run out of the other. I noticed that the Zote soap absolutely would not dissolve in cold water. It ruined three of my good sweaters as I had soap stick to them and not wash out, even after three more trips through the washer without detergent. I say all of this to ask if you are happy with the Dr. Bronner soap dissolving in cold water? Thanks!

  5. I love making homemade laundry detergent! We switched over about a year ago and I will never go back!5 stars

  6. thanks for linking up to the frugal tuesday tip!

  7. I have the ingredients for a very similar recipe, but because I have hard water I have to use a liquid recipe. So its the same ingredients plus lots of hot water and it actually decreases the cost. For dirty, dirty loads I am told I can throw in about 1 c of Borax.
    I am off to try this this weekend (while out camping – what better time to grate a 4 oz bar of soap) and then boil it up on return and use it to do the laundry ๐Ÿ™‚
    Glad I found your blog, your funny and remind me a little of me… with a better sense of humor ๐Ÿ™‚5 stars

  8. I’ve been thinking about this but didn’t know how. The cost info is really interesting.5 stars

  9. Thanks for the monetary breakdown! This is the recipe I use but it’s much more persuasive when you include just how much money we’re saving. I love never having those giant containers around! THank you for contributing to Simple Lives Thursday!5 stars

  10. Thanks for the recipe! I will have to give this a try.
    Also, creepy doomsday soap made me laugh so hard (and I’m at work, oops!) because it sounds like something my mom would totally do too.
    I’m glad I found your blog!5 stars
