I've heard that adding a teaspoon of TSP can be helpful because a lot of the dishwashing detergents are now phosphate free.

TSP == Trisodium phosphate. Available at many stores.

If your water is hard, this will prevent water spots or scale from forming.

Do not use TSP! Use sodiumtrippolyphosphate, aka STP, STPP. TSP is as caustic as lye. You can find STP on Amazon.

Mix 30% STPP with powder for hard water. 10% for soft water.
