You can save a ton of money on laundry
soap. At Sam's Club we could pay $25 for 180 loads worth of Tide but
making this recipe only costs about $3 for 5 gallons! Making it takes
about 10 - 15 minutes and it's not complicated. HERE is a video of the Duggars making their laundry soap and saving lots of money in other ways. HERE is a thorough video of the process.
You will need these three ingredients and a 5 gallon bucket, a long stirring stick or spoon, a pot, a whisk and a measuring cup. At Walmart each bar of Fels is $1 and the Soda and Borax might be $3 - $4 each, but you only use a little for every 5 gallon bucket. Because the Fels is only $1, I buy a few bars so that I never run out of detergent at the last minute.
Grate the bar of soap. From what I understand, you can use any bar of soap.
Melt down the soap in hot water on the stove over medium heat stirring constantly until no chunks remain. If the temp is too high or you neglect to stir, then the soap will boil over.
Add diluted soap, 1/2 cup of borax & 1 cup of washing soda to a 5 gallon bucket. Some recipes use different amounts of borax & washing soda but all are fine and good. Fill the remainder of the bucket with hot water. If you like to add scented oils, now is probably the time to do it.
Stir. Place the lid on top and allow to rest overnight.
