Homemade laundry detergent-powder

6 cups Borax, 4 cups baking soda, 4 cups washing soda, 4 cups bar soap (Zote, Fels-Naptha, or octagon). Use 1/8 cup per full load. This makes quite a bit. I grate the bar soap. Then, I put it in a food processor w/ a little of the powder mixture. It will make the soap turn in to smaller pieces & compacts better w/ the powder & mixes well. Baking soda & washing soda are different. Zote soap is bigger. So, it takes 2 bars of it for the above amt. I find it at Wal-Mart. Fels-Naptha can be found at Harris Teeter. It takes 4 bars of it for the above mix. It's a tougher bar of soap which makes it take longer to grate. Octagon soap can be found at Food Lion. It's also a tough bar which takes longer to grate & you will need 4 bars of it for the above mix. I recommend Zote. It runs cheaper than the others & is much easier & quicker to grate. I have a front loading washer & have purchased the Purex fabric softener crystals & put it in the washer to add a nice scent. I haven't tried the Gain or Downy pellet type fabric softeners yet but I'm eager to try them.
