Cheap and Easy Laundry Soap

I found this recipe on Pinterest last year.  A friend of mine made the liquid clothes soap and loves it.  I found the process for the liquid to be too messy.  I usually buy liquid clothes soap because I have had problems with it clumping in the wash, but you only use a tablespoon or so of this, so there isn't enough to clump.  It takes less than ten minutes to make and lasts forever.  I made some of this this past summer and just now was starting to get close to the bottom of the bucket... I probably had another month's worth left. 
This is what you need:

 

I found everything at Walmart on the clothes soap isle. 
1 box 20 Mule Team Borax
1 box Arm and Hammer Super Washing Soda
1 large box Arm and Hammer Pure Baking Soda
1 Box Oxi Clean
1 bottle Purex Crystals (these are optional, but they make everything smell nice)
2 bars of FelsNaptha laundry soap

Other sites say to microwave the felsnaptha soap.  This is supposed to make it puff up and easy to crumble.  I found that it did puff up, but it got kind of gummy, not really crumbly, and I burnt my fingers on it.  It was really easy to grate fresh out of the wrapper.  I used a cheese grater.

Once you grate the bar soap, you just put everything in a bucket and stir it together.  I did half at a time.  Then you use 1 tablespoon per load of laundry.  I put in a little more if I have a super large load.
