Liquid Laundry Detergent
1 cup Washing Soda
1/2 cup Borax
a bit of tea tree oil (to cut the mildew smell front loaders can have!)
1/4 cup or so of Dr. Bronner's Baby Castile liquid soap
4 cups hot water (first) then added about 8 more cups
**My mom pointed out that this makes a VERY concentrated soap. It does! If you use this recipe you'll only need a tablespoon or so for each load. She uses quarts instead of cups of water in her recipe (same amounts of everything else) and it makes a not-as-concentrated recipe that you'd use a capful of a normal washing bottle. I am using the quart method now myself because the other was overflowing!
I mixed it in a bowl with a whisk because the washing soda (soda ash) gets hot when it gets wet. (Luckily I knew this from my pool or I'd have probably burned my hands trying to get the clumps out.) I did put the end of it in the blender and mixed it there to try and get all the clumps out. Here are more recipes.
