Aaron whipped up our batch of dishwasher detergent yesterday and we ran our first load and it worked wonderfully! We used a simple formula of 1c Washing soda, 1c borax, 1/2c citric acid, and 1/2c salt. We are also using vinegar as our rinse agent but you can also use lemon juice.
citric acid causes the moisture We did some reading and found a few different solutions.
1. Adding rice would eliminate the moisture although I don't know that rice is good for dishwashers.
2. Leaving the mixture out and stir a few times a day for a few days keeping lid on after stirring.
3. Add citric acid separately to each load.
4. Put the mixture into ice cube containers and make into blocks, then seal in an air tight container.
We are leaving it out on the counter and stirring it for a few days and will see if that works out for us.
