Home-Made Dish­washer Detergent

Here’s a plan: Mix up a home-made dish­washer detergent that really works, does not pollute our water, and saves you money too!  The final cost is only half as much as commercial dishwasher deter­gent. Instead of the usual rinse agent, fill the rinse-agent compartment with white vinegar for a whop­ping 6650% savings! (not a misprint.)


  • 1 cup borax
  • 1cup washing soda
  • ½ cup salt
  • ½ cup citric acid

Use one rounded tablespoon per load.

One of our members made this detergent and swears the dishes come out sparkling clean.  He also says that the citric acid causes the mixture to clump up a bit.  To solve this problem, keep and add it separately or mix it all up and leave it out for a couple of days and stir/break it up a couple of times per day, then store.  There are step-by-step instructions at the following website:­jabs-homemade-dishwasher-detergent-rinse­agent/  The Citric Acid is available in bulk at the Wil­limantic Food Coop on their spice shelves.  It is also available at local breweries or online (Citric Acid.)
