This is not my idea, but I’ve been using this one batch for a year. What I learned: make this in good weather, outside, on a windless day.
I got this recipe from
Home is where the Library is · A stay-at-home mom and archivist tackles life
Homemade Laundry Detergent
1 box super washing soda
1 box borax
2 bars of Felsnapath (grated finely)
1 tub Oxygenated Bleach (Oxi Clean)
1 large container Purex Crystals, aroma of choice
Method: Grate the Felsnapath soap using a food processor. Add in a scoop of oxi-lean or borax and pulse until it resembles fine crumbs (the addition of powder helps the soap from clumping). Combine the ingredients 1 cup at a time, mix together, then repeat until all components are used.
If only I had read this little detail. I used a box grater on the bar soap not the food processor. Go with the food processor.
There are other recipes on Pinterest and blogs. They call for 1 cup of this and a cup and a half of that. I only bought all this stuff to make laundry soap. The recipe that calls for a whole box of this and a whole bar of that is a better idea.
Before you start, decide what kind of container you will use for this huge amount of laundry detergent. I used a popcorn can. Then we scoop some of the laundry detergent back into the oxi-clean container to use near the wash machine.
Plus, there is a measuring scoop in the Oxi-Clean, which is handy. The big can will be stored in the closet. Only the small Oxi-Clean (home-made laundry detergent) container is exposed to the air and humidity. Good thing because this batch of laundry soap will last us for a couple of years.
