I must update my comment in post# 28. It doesn’t put phosphates in the soap mix. Rather, it creates sodium carbonate (washing soda) and hydrogen peroxide to get the wash load clean. It is safer than TSP because it doesn’t have the harsher chemical base of TSP, which I believe is chlorine based. But Oxi-Clean does work great on getting clothes clean.
Your belief needs to go back to chemistry class.
TSP stands for Tri-Sodium-Phosphate. There is no chlorine in it.
