Mix together:
- 1 cup Arm & Hammer (or other brand) washing soda –not baking soda
- 1 cup borax
- 2 cups (or approximately 1 bar) very finely grated Fels Naptha laundry bar — some people prefer Zote brand soap
Use two tablespoons for a large load (adjust for smaller or less soiled loads of clothes).
I found all these products at the end of the laundry area in the grocery store. They are also available in Walmart. My parents are giving this a try too, and they found these products at Ace Hardware.
Update: I have been using this detergent for years, which tells you I’m very pleased with it.
I hope you’ll consider giving this DIY laundry detergent recipe a try. It’s so easy to make a part of your routine, and you’ll feel great when you get to walk past those expensive detergents in the laundry aisle.
