Here is the recipe that I follow for my Snot Laundry Detergent...I'm still thinking up names for it right now, but for now, I call it Snot.
Homemade Laundry Soap
1/3 bar Fels Naptha
½ cup washing soda
½ cup borax powder
~You will also need a small bucket, about 2 gallon size~
Grate the soap and put it in a sauce pan. Add 6 cups water and heat it until the soap melts. Add the washing soda and the borax and stir until it is dissolved. Remove from heat. Pour 4 cups hot water into the bucket. Now add your soap mixture and stir. Now add 1 gallon plus 6 cups of water and stir. Let the soap sit for about 24 hours and it will gel. You use ½ cup per load.
Optional: If you want your soap to have some sort of scent you can scent this with ½ to 1 oz. of essential oil or fragrance oil of your choice. Note: I don't add any scent. I think it smells great without it. Also, there is no scent when the clothes come out of the dryer.
Just some notes:
The finished product will look like snot. Seriously.
There will be practically no suds. None. Nada. Zilch. Totally normal. The ingredients are what does the cleaning anyway. Not the suds.
