Economical Homemade Liquid Laundry Soap

This homemade laundry soap can really help save money, plus it seems to work as well as the store bought soap. It cost about .30 cents per gallon to make! Prep time does not include letting the mixture set for 24 hours. NOTE I still use Downy in my Downy Ball to make my clothes soft!

I use a recipe similar to this I found online. The recipe I use calls for exact measurements of water and it yields 2 gallons. Other than the water amounts the rest of ingredients are the same. Yes, it is supposed to be a gel like substance. It helps to stir or shake before each use. We have a front loader that uses conserves water and I have had no trouble using this soap on anything. At first I worried the fels naptha would be too strong for my toddler but it's fine. It gets your clothes super clean without leaving any residue behind. I have used a downy ball with white vinegar in the rinse but found it wasn't necessary. I've given this laundry soap to friends and all have raved over it and ask for the recipe. As much laundry as I do, it costs pennies a load now. I've been making my own laundry soap since spring 2009.

This is my recipe too! (I got it from The Queen of Clean.) I add about 10 drops of Sweet Orange essential oil to it. LOVELY!
