About a month ago I decided to try doing homemade laundry cleaner rather than continuing to buy conventional detergents or their eco-friendly counterparts. So I did a little research online, and settled on a recipe that called for 2 tbsp castile soap, 1 c washing soda, 1 c baking soda, and 1 c vinegar.
First obstacle, can't find washing soda anywhere. No one sells it. Did a little more online research, found out it's sodium carbonate, and can be found sold as the pool chemical PhPlus. I did find that, paid $10 for it, and it's almost gone now.
Next, I found out just how tough it is to keep enough baking soda in the house to put 1 cup in every load of laundry! I've probably bought another $6 or $7 worth of baking soda in the past month.
I paid $15 for the bottle of castile soap, and I've used about 1/4 of it, and almost exclusively on the laundry. So that's about $4.
The vinegar was the cheapest; I think I paid $2 for the gallon and I do use that for other things, but I would estimate that about half of it has been on the laundry, so that's another $1.
So in total, I have spent over $20 to wash my clothes for a month. I could order the washing soda online, but once you factor in shipping, it's not going to be that much less money. I thought making your own was supposed to be LESS expensive??
