Making laundry detergent shaffo

I decided to make my own laundry detergent. I used 1/2 bar zout, 2 c of laundry soda and 1 c oxiclean (allergic to boxax). I melted zout in 1 gallon of hot water. Then I added the soda and oxiclean. OMW It exploded like a valcano. I was mixing in 5 gallon bucket and had to use several of my large pans (plus what bubbled over onto the floor in my frantic attempt to find more vessels). After it cooled the foam has condenced into a dense, foam. I have stirred and stirred and the foam and the liquid will not mix. SO, my question is- do I use the liquid or the foam or some of each?
