Here's my shopping list and recipe for my homemade dishwasher detergent: 1 cup Washing Soda •1 cup Borax •½ cup Citric Acid •½ Sea Salt •20 drops of lemon essential oil •Mix it all together in a 32 oz Ball (Mason) jar. Use 1 tablespoon per load.*Most of these items have lasted me over a year and it's such a great, low-tox option. LTKHome LTKFindsUnder50 LTKU
