My math on the cost wasn't entirely correct. $20 is NOT the cost per year. $20 is
the cost of the initial investment of one box of borax, one box of washing soda and
one bar of Fels Naptha soap. However, the boxes of Borax and soda go a long long
way and probably make a couple hundred gallons of laundry detergent with the additional
cost of a bar of the Fels for every 10 gallons.
In short 1.32 gallons of the brand name I was buying at Sam's Club cost about $19-20,
but 1.32 gallons of this homemade soap costs me $0.66 and less than a half hour to
make 10 gallons of the stuff. So I'm saving $19 per jug of laundry soap.
The formula is
1 bar of Fels Naptha Soap
1 Cup of Washing Soda
1/2 Cup Borax
Other items you will need:
Safety goggles protect your eyes from the soapy mix during the process
Oven mitts to safely handle hot pans etc
Cheese grater or a food processor
Big spoons, wisps or a cordless drill with a clean paint mixer attachment (NOTE:
If you use a corded drill with a paint mixer, do yourself a favor and make sure to
plug the drill into a GFI outlet to help protect you from electric shock!)
One clean 5-gallon bucket with available lid
Empty jugs to put the final mixed laundry detergent in
A funnel and a quart size container to make transferring the laundry detergent easier
Common sense don't do anything stupid, don't goof around the soap and get it in your
eyes or someone else's eyes.
Grate 1 bar of Fels Naptha Soap into small particles.
Slowly mix the grated soap into 4-8 cups warm water in a sauce pan over medium heat
until all of the soap is completely dissolved.
Mix the washing soda and Borax into about a gallon of warm to hot water in a 5 gallon
Mix the melted Fels Naptha Soap into the 5 gallon bucket.
Slowly add hot tap water to the 5 gallon bucket and mix it as it fills to the 5 gallon
Put the lid on the 5 gallon bucket and let it sit overnight.
Uncover the 5 gallon bucket. The soapy mix may have gelled over night.
Stir this soapy mix until the gel becomes liquid (a drill and paint mixer work really
Transfer the soapy mix into secondary jugs (old laundry detergent jugs, used milk
jugs whatever you want).
When transferring use a funnel and mix the soapy mix 50/50 with water.
Makes 10 Gallons of laundry detergent
Suggested Use Instructions:
Top loading machine = 1/2 cup per load
Front loading machine = 1/4 cup per load
I've heard that some people will add a 10-15 drops of essential or other things to
add a desired odor to the soap.
I kind of erred in my math in the video regarding the cost.
About $20 will buy one box of Borax, one box of washing soda and one bar of Fels
The boxes of Borax and washing soda will provide enough to make several 10 gallon
batches of laundry soap.
However, you will need to buy a bar of the Fels Naptha soap for each batch of 10
But that's only about $4.00.
Currently I am on my 3rd or 4th 10 gallon batch and I still have plenty of the Borax
and washing soda left.
So after buying a total of four bars of Fels Naptha Soap, plus a box of Borax and
and a box of washing soda, my cost is about $32 for 40 gallons of laundry detergent.
That's less than what 2-3 gallons of name brand laundry soap would have cost me!
