● 1 cup washing soda ($5.99/box at Ace Hardware)
● 1/2 cup citric acid powder ($28 for 5lbs at Amazon or check your bulk aisle)
● 1/2 cup kosher salt
Mix ingredients together and use 1 tablespoon per load. This detergent will clump together because of the citric acid but it doesn't affect the product in any way.
Fill rinse agent compartment with white vinegar.
I also want to make a note that the biggest motivation in making my own cleaning products is not saving money at all. That part is nice, but I love that I can clean with natural ingredients and keep my family safe from toxins as well as reduce waste.
