I think I've jumped on that band wagon and will not return. Actually, I don't know if that's true or not! I've been wanting to make my own soap for while, however I've not been sure on which directions to follow. They all pretty much use the same items, but the water to detergent ratios are different in each recipe I found. Sometimes it's 2 gallons, sometimes 5 gallons, or somewhere in between. So I settled on doing a dry powder mix.
The one I really wanted to try the most was just a very big patch to try. The est. cost would have been around $20 and would have last 9 months to a year. However, I just didn't want to spend money making such a large batch in fear I would not like it.
So I found a similar recipe to try. The one I went with only used 1/2 cup of borax, 1/2 cup of washing soda, and one bar of soap. I had the borax, washing soda, and 1 bar of fels naptha on hand, because when I mention to my friends I wanted to try making my own soap, one of them stepped up and gave me the ingredients for free. (She tried making soap, but didn't like the results so she gave me what she didn't used).
I made the small batched and have washed just one load. So far okay, but over time I'll know for sure. If this seems to work out well, then I might step it up and do the larger batch seeing it has other items added to help fight of stains. Right now I'm using the the stain fighters I normally use.
