  • Total Time: 5 minutes
  • Yield: 58 loads 1x
  • Category: DIY cleaners

Ingredients

Scale

1 cup washing soda

1 cup baking soda

1 cup citric acid

2/3 cup table salt**

Instructions

  1. Combine all ingredients in a quart size glass jar and shake until well combined. 
  2. Use 1 Tablespoon of detergent per normal load. Adjust as necessary for larger or smaller appliances.
  3. Store in a cool, dry area away from any moisture.***

Notes

** Any type of salt will work well. I’ve used table salt and pink Himalayan sea salt. Feel free to use whatever you have on hand!

*** Storing DIY dishwasher powder correctly is super important. Improper storage in a humid or damp area  could result in a hard, caked together mass due to how moisture interacts with citric acid. Keep it dry by adding a reusable tea bag of rice in the jar, or reuse a silica gel pack inside the container.
