A quarter teaspoon of TSP (trisodium phosphate), available at your hardware store, works wonders.

Do I just toss it in the soap dispenser with the soap? The first one or the second? Or does it matter?

“Do I just toss it in the soap dispenser with the soap?”

I spread 1/4 teaspoon between the prewash and regular wash compartments before I close the compartment lid.
