Homemade Laundry Soap

So many have asked for a recipe for laundry soap. Your search is now over. I want to thank an awesome friend Leatta, for allowing me to share her perfected homemade laundry soap recipe.  It leaves a fresh clean laundry smell. Only costs $0.86 per 64 loads – and meets the h.e. requirements for energy efficient front loaders. If you prefer to use powdered laundry detergent, we have that recipe too! Stretch your money further with Valerie’s Homemade Fabric Softener.

Homemade Laundry Soap Ingredients

You will need:

1 bar of Fels-Naptha Soap (if you don’t have heavy stains, Ivory works fine)
1.5 Cups Arm & Hammer Super Washing Soda (NOT Baking Soda)
3/4 Cup Borax
Lemongrass or other Essential oil (I use Lemon and love the scent!)
(It is also VERY helpful to have a funnel and a slotted spoon)

Pre-fill (5) one-gallon jugs 1/2 full of water (distilled or pre-boiled water is recommended to prevent bacteria growth…most people use tap water). If you are going to add an essential oil, put about 5 drops in each jug with the water. Lemongrass oil offers a wonderful, clean smell and is also antimicrobial. Which means, it helps kill stuff like ringworm, athletes foot, etc.

Next grate the bar of Soap using a cheese grater. Put shavings in a pan with 8 cups of water. Warm over medium heat until completely dissolved.  Turn down the heat if it starts to boil. This is where the slotted spoon is helpful because the water gets really milky and its hard to tell when its melted.

Remove from heat and make sure it is not boiling. Stir in the Washing Soda and Borax. Add to 2 gallons of water & stir some more.

Using a funnel, top off each 1/2 filled with water container. Put the lid on & shake, shake, shake.

To Use: Shake the jug before each use. Place 1/3 cup per load.

Note: It will gel, but not always to the same thickness. Using distilled water increases the thickness of the gel.

SAFETY NOTE:  Since you may be reusing milk jugs, apple juice containers, or other already labeled containers, it is important that kids know it is NOT food.  Please label containers accordingly.

  1. Where do you find all of the ingredients at if you can’t find them at the grocery store? Thanks, Lisa

  2. Michelle C says

    I’ve been making this for close to 2 years and love it! It’s great!

  3. I found all the ingredients at WalMart.

  4. Do you know if this is hypoallergenic. I have to use fragrance free soap. I can only use tide free

  5. Is this safe for HE washers?

  6. I love this recipe, have made it three times but there is only my husband me left at home so i make a 1/2 batch. I have also learned that using a paring knife instead of a grater works better for me. If you do not apply too much pressure if creates an almost power like soap VS grater pieces, melts easier/faster. Thanks so much for sharing this recipe!
