When the dish washings soaps went phosphate free I started adding white vinegar to the rinse agent. Ended the spotty utensils and glasses.
Now I have to add a color safe bleach to the laundry in order to get clothes clean.
Also, TSP, from Home Depot works well, too. Trisodium Phosphate is used by painters to clean walls before painting. Just a hair of it with the detergent puts back that phosphate. I keep it in a sugar dispenser to pour into the detergent reservoir.
