I have completed my soap and will be storing it in blue ball jars with zinc lids because it looks nice, but you can store it in anything from a zip top bag to a plastic container. I have washed my first load - towels - and did not add a drier sheet. The towels are still fresh and fluffy. Not saying I will never use drier sheets again, just wanted to see an outcome.
To Use: Add 1 to 3 teaspoons per load, depending on size of load and amount of dirt to be removed. Please note: This is not a sudsing soap. You won't see bubbles, but it is working.
Another tip I received: You can add Oxi Clean for extra stain fighting power. I have not done so (I didn't have any), but you can also add it on a load by load basis.
I found all items at my local grocery store and I purchased the following:
1 Bar Fels Naptha Soap
1 Box Borax
1 Box Washing Soda
Grate the bar of soap with a cheese grater.
You should get about three cups.
Add 2 1/4 cups Washing Soda AND 2 1/4 Cups Borax (1 Used a 1:.75:.75 ratio, but you can use anywhere from 1:.5:.5 to 1:1:1)
Put all ingredients into a food processor.
Pulse until powdered - keep the lid on the processor for a few minutes until the dust settles.
Place in an air tight container.
