1 Tablespoon of Bicarb Soda
1 Tablespoon of Borax
Mix well.
I make quite a bit of this at a time and store in an airtight container and use when needed.
Another recipe is:
1 cup Bicarb Soda
1 cup Washing Soda
1/4 cup salt
1/4 cup citric acid
Few drops of tea tree oil
Shake together and store in an airtight container. Use 2 tablespoons per load.
I have not used this one, so I don’t know how well it works.
Another recipe is:
1/2 cup borax
1/2 cup washing soda
Juice of 1 lemon
Mix together. Use 2 Tablespoons of the mixture. (I got this recipe from Here.)

I also turn off the dishwasher during the drying cycle after all the water has exited the machine and open the door and let them air dry. This helps save on power costs.
