Making your own laundry soap is really easy. You will only need 3 ingredients.
Fel-naptha bar soap
The ratio is 1 cup grated soap, 1/2 cup washing soda and 1/2 cup borax.
I have found that 5 bars of soap and a box of each borax and washing soda make a batch of laundry soap. It makes almost 2 gallons of dry soap.
Use a tablespoon per load of laundry. Great for front loading washers. Its also dye and fragrance free. Which is great for me since Ben is allergic to something in most laundry detergents.
