diy dishwasher detergent & rinse

i’ve posted on diy dish soap before, but those recipes are a little too runny to put into the dishwasher. this recipe is thicker, and can be followed up with the diy rinse.

… and to be honest, i now have a dishwasher. talk about excitement!


these recipes are super simple and can be stored in virtually any container.


  • 1 cup finely ground & tightly packed castile bar soap (like dr bronners)
  • 1/4 cup salt (any salt)
  • 1/2 cup washing soda
  • 1/4 cup baking soda

mix all ingredients and store in an air-tight container. use 1 tablespoon per load.


  • 1 cup liquid castile soap
  • 1/2 tablespoon salt

mix salt into soap slowly and stir as you go. it’ll thicken up a bit. put into a pump bottle for easy storage and use. this is what i currently prefer. i use 2 pumps in my dishwasher and have never been left with a bubbly mess. maybe test it with 1 first.


  • 3/4 cup vinegar (any kind, but i prefer apple cider vinegar)

for this rinse, either place directly into your rinse aid compartment, or stop your dishwasher before the rinse cycle, and place a small cup full of the vinegar on the top shelf.


please leave your dish soap and rinse recipes below!

NOTE: please note that newer dishwashers with rubber rinse aid compartments can degrade from the acidic vinegar over time. if that’s a concern for your particular dishwasher, you can place a small cup on the top shelf of your dishwasher with the rinse aid in it after the wash cycle. this will still rinse your dishes, yet it will avoid the rubber compartments.

    1. hey jenny! the salt thickens up the liquid version so it’s not super runny, and also helps “demineralize” the water. it’s especially helpful if you have hard water 🙂 hope this helps!

  1. Hi Alex! I will definitely have to try these out as I haven’t found a good diy dishwasher solution yet. Question for you: I recently bought a new bottle of Dr. Bronners soap and it seemed runnier and not as concentrated as usual. I typically dilute the tea tree soap to maybe a 1:3 or 1:4 ratio to put into foaming pump containers for hand soap which ends up having a pale color. I did the same with the new bottle and it ended up having almost no color left after diluting. Have you noticed this at all? I’m hoping I just may have gotten a weird batch and they’re not diluting their soap now (the label does look brighter/updated on the new bottle).

    1. hey meghan! you might be onto something or you might have a weird batch. i just put some of the lavender soap on my fingers and it’s still sticky and thicker on its own. the citrus was less sticky. maybe it’s the scents? I honestly have no idea and don’t have an old bottle to compare it to. someone please help! :):)
