here it is...i always double it:
1 qt. boiling water (4 c)
2 c bar soap grated (1/2 bar)
2 c borax
2 c washing soda
here are my main ingredients:
boil the 4 cups of water in a big pot. while it's starting to boil, grate the bar of soap. (i've found that if you use a finer grater, it melts more easily)
add to boiling water.
and keep stirring until melted (if you keep the temp on med/high, i've found it melts more easily)
after completely melted, transfer to a large clean pail. (i use a 12 L rubbermaid container from the container store)
then add washing soda...
and stir until dissolved. i like to use a wisk :)
next add 2 gallons of water (4 quarts)
stir until mixed
it tends to separate after the initial stir...
so, you might need to wisk it a couple more times. then it looks like this and is ready to use!
the doubled batch that i make ends up being 4 gallons of laundry soap! you use 1 cup for each load of laundry at a time. i hope this comes in handy and saves you some $$ too!
