Best homemade laundry soap

My mom told me about this laundry soap she found on Pinterest. She sent me over some samples and I was in love. I made up my own batch for less than $15. I use 1 tablespoon. This stuff gets out blood, stains and puppy messes. I'm in love with it. My husband is allergic to some brands and so far we haven't had a problem. Warning this makes a large batch. I mixed mine up outside in a 5 gallon container with lid. I do a lot of laundry, 3-4 loads a day and I predict this batch will last us 3-4 months. That's a lot of savings!

We purchased a box of:
Baking Soda
Baking soda wash
20 Borax Mule
3 bars of Fels-Naptha soap- I put mine in the food processor, worked perfectly. Much faster/easier than grinding it.

This summer I've been mama to newborn puppies and kittens, bottlefeeding, changing, washing, bathing towels, rangs and more towels. This laundry soap has been wonderful for this. Highly recommended. We love it!
