I have FINALLY used up the bottle of laundry detergent I bought at at beginning of June when we moved in to the hotel for 9 weeks. Time to make a batch of homemade stuff! When we lived in IL, I made a very large liquid batch that I had to store in a 5 gallon bucket. This time, I knew I wanted to try powder.
There are tons of recipes on the internet, but they all use the same basic ingredients... a bar of castile soap, washing soda, and Borax.
Using a grater (or food processor if you want), shred half the bar of soap (which will give you about a cups worth of shavings).
Mix together with 1 cup of Borax and 1 cup of washing soda (NOT baking soda). Shake it up good. You want it to be well blended.
Use 1 Tbl per load. It will NOT suds up, so is safe to use in front-loaders.
