Now that's interesting. I looked it up. TSP-PF. The name is kind of silly since TSP stands for trisodium phosphate. They add PF "phosphate free" to the name. Trisodium Phosphate-Phosphate Free. I guess TSP is such a well known product that they didn't want to lose the recognition for their product. I'll have to look for the green box though as I have some serious scrubbing to do around the house.
