For about 2 years now I've been making laundry soap. It's cheaper, doesn't irritate our skin, leaves our clothes much fresher longer and doesn't build up inside the washer. This recipe makes a nice powder that dissolves easily and smells nice! It's made with all natural ingredients but I would recommend mixing it in a well ventilated area away from the kids!
1 bar Fels Naptha Soap ($1.25)
1/2 76 oz. box Borax ($1.75)
1 box Arm and Hammer Super Washing Soda ($2.25)
Grate the soap using cheese grater .. I have one I picked up a thrift store that's only used for soap! Mix all ingredients in a large container, I got a plastic cookie jar with a screw on top from a dollar store that works well .. I dump everything in and shake .. then wait a bit to let the dust settle.
To use in washer: Add 1/8 cup to washer as it's filling, swish a bit to dissolve, and add laundry. This batch usually lasts us 2-3 months, even with a 3 1/2 year old that loves to play dress up 3-4 times a day!
It works for me!
