Yesterday I read all 21 pages of this thread and was just tickled to death to find it. I made a shopping list and off I went for the laundry supplies.
Unfortunately, what I DIDN'T read was the clickable links. I should have. First, I went to Wal mart. I found the borax. Next to it on the shelf was the big orange box of A&H with a picture of laundry on the front. But it said baking soda, even though it was sitting there, in its big old box, right there with the laundry stuff. I bought it and went on to the dollar store, where I had no luck finding any of it. Then I went to Kroger and they had all three ingredients. I went ahead and bought the fels naptha and washing soda and went home to find out the difference between washing soda and baking soda. (This is where the clickable links would have saved me a couple bucks since someone posted the difference in the two earlier)
Baking soda is sodium bicarbonate and washing soda is sodium carbonate. You might be able to use baking soda in your wash but you sure can't use washing soda in your baking.
Now I have a BIG box of baking soda...mmmmm, what to do with it?
Also, I noticed people praising Dawn dish liquid. Years ago I had a job in plant maintenance. Tropicals mostly. And we used dawn for a couple of things. If your houseplants have spider mite, put a couple of drops of dawn (for some reason, it has to be the original blue stuff) in a spray bottle, fill with water and spray your plants. This will also work on those pesky gnats that sometimes live in the soil of your houseplants.
