1 cup Borax
1 cup washing soda
1/2 cup citric acid
1/2 cup kosher salt
Use one rounded tablespoon per load.
Ok, you already have the washing soda and Borax from the laundry detergent. For the citric acid you can use 4 packets of lemon Kool-aid or 1/2 cup of Lemi Shine which can be found in places like WalMart or Target. Amazon.com sells it as well but it’s more expensive there. You can get food grade citric acid on Amazon for pretty cheap. Going through Amazon is actually more expensive for Borax and washing soda than it is to buy it at the market. I found the combo of both of them together for $16 on Amazon but bought them both for about $8 total at the store. I’m sure I could have found them cheaper but this was during my “I want to play at being Susie Homemaker” phase. As in all things, shop around.
For a rinse agent, fill your rinse agent cup with white vinegar.
*** I haven’t tried this yet. We have a bunch of dish detergent that we’re going to use up before I need to try this. However, this is the most common recipe I see and it’s the one I am going to try. I’ll let you know how it goes.
