I have been making liquid laundry detergent since around 2016, possibly earlier. With six people and around 427 loads of laundry to do weekly, there had to be a less expensive way to do the laundry. After hours of research, testing out many recipes, this recipe for liquid laundry soap has been a winner for years. Now, after months of trials, I have finally found out the perfect way to add a little booster to the laundry soap. Bring in the scent crystals to help Freshen Laundry Soap.

Laundry Soap Recipe
Ingredients
1 cup each of Borax Detergent Booster
5-ounce Fels-Naptha Laundry Bar
1 cup Arm & Hammer Laundry Booster Super Washing Soda
Water
1 cup Downy Unstopables Laundry Scent Crystals
5-gallon bucket

Directions
1. Using a box shredder, shred the bar of Fels-Naptha with a box grater into a large pot on the stove.
2. Add 4 cups of water to the Fels-Naptha in the pot and set the temperature to Medium.

3. Add 1 cup of Downy Unstopables Scent Crystals to the water and soap mixture, then whisk the solution for 10-minutes or until the Fels-Naptha soap is fully dissolved in the water.


4. Fill up half of a 5-gallon bucket with hot water.

5. Add 1 cup each of Borax Laundry Detergent Booster and Arm & Hammer Super Washing Soda, then whisk well into the bucket.



6. Carefully pour the Fels-Naptha water mixture into the 5-gallon bucket, then whisk well.



7. Fill the pot that held the water mixture and make sure to get all of the soap, then pour it into the 5-gallon bucket and whisk well.


8. Fill the rest of the 5-gallon bucket with hot water, within 1-inch of the rim, then cover the bucket and let it rest for 24-hours.


9. After a day of sitting, use an emersion blender to mix the laundry detergent completely as it will be lumpy and not smooth.



10. Use a large cup or measuring bowl to scoop and pour the laundry detergent into a small bottle. I recommend saving a bottle, washing it and using it for a homemade laundry detergent bottle to refill. I have not bought a bottle of laundry detergent since 2016 or so.


11. Each load typically uses 1/3 cup of homemade Liquid Laundry Soap. As the measuring cup was used to fill the bottle, it was then used to add detergent into the washer. Pro-tip: always rinse the cup in the running water to utilize all of it for the load, then the cup stays clean as well.

12. Cover the 5-gallon bucket and then set aside for a different time.


Enjoy your freshened laundry detergent!
