Well here is me trying to work through that huge box of All with the Three B's when it hit me; instead of adding a small scoop of STPP to liquid laundry detergents, just use the All instead.
Now before anyone calls me a Danish, here is the method to my madness.
Laundry boosters sold in the past and today contain often alkaline substances (washing soda, borax, phosphates, etc...) to help performance. Indeed much of what is being sold today by P&G, Henkel and others in those "stain release" pods is oxygen bleach along with washing soda and enzymes.
Condensed All (the condensed by the way one found out refers to phosphates) already has STPP along with borax and IIRC some soda along with surfactants and bluing agents. So there you are then.
