We have been making laundry soap since 2009. I wish I would have know how simple it was to make back when I first started having kiddos. It is three ingredients: fels-naptha soap, borax, and washing soda. I use a bar of the soap grated and dissolved with six cups of water heated. I add a cup each of borax and washing soda. I dont know if it is right or not I just know it jells and cleans the clothes.
We made a video of the first time making it after watching a couple videos ourselves. It was hilarious trying to make our own video. I made something so easy look hard but we sure had fun doing it. If you watch the video you get a little glimpse into our life here.
I make soap super simple now loads easier. Maybe I will make another video to show you but the kids are grown and I am not sure how to make it as adorable.
