I grated a bar of Fels-Naptha and set aside 1 1/3 cup for another batch. I used my food processor for this. I add this to a kettle on the stove to 4 cups water. Heat to dissolve the soap. Meanwhile, measure out 1/2 cup each of soda and borax.
Add 4 cups hot water to a storage container. Add melted mixture to the storage container plus 1 gallon and 6 cups water. Mix.
This container is huge. I will more than likely put it in a smaller container plus I have a milk jug I will put some into for daily use.
The information below I got from another blog. She also had a video tutorial, if anyone is interested. I didn't keep tract of my prices. Next time I will and give you an update.
All calculations are based on the national avg. of 400 loads of laundry per family per year, or 7.69 loads per week
Tide $12.99/64 loads .20/load=$80/yr
Gain $5.99/32 loads .19/load=$76/yr
All $4.29/32 loads .13/load=$52/yr
Trend $2.49/38 loads .7/load=$28/yr
(generic brand)
Fels Naptha soap $1.19/bar
Arm&Hammer Super Washing Soda $2.99/55oz box
20 Mule Team Borax $4.49/76 oz box
One box of the washing soda will make just under 7 batches of soap, and the borax will make exactly 19 batches.
One batch of soap calculates out to:
$1.19/Fels Naptha
.49/Washing soda
.24/Borax
$1.92 per 10 gallons
10 gal (64oz) divided by 2 oz./load=320 loads/batch=.006/load
Final cost per year=$2.40!!!!!!!!!!
Now that's a great bottom line! Please post a comment and let me know if you try this and what you think.
