I've used simply equal parts of borax and washing soda for laundry detergent, and have loved the results. Everything smelled fresh, but not smelly.
The only thing is the cost isn't much better than Arm and Hammer detergent, and its a hassle to find the washing soda (only place I know has it, is 45 min away where we used to live).
I see people post how cheap it is, and that they found an inexpensive source, but the only places I have seen both the washing soda and the borax, add up to a regular bottle of detergent...
So, I'm just wondering what IS a good price? And where do you get it?
