I know that people have asked about something like this a number of times, and I just heard about this one. I intend to try it as soon as my box of Trader Joe’s is used up.

In a mason jar, mix:
1 cup borax
1 cup baking soda
1/4 cup salt
1/4 cup citric acid
30 drops citrus essential oil–lemon, grapefruit, orange, tangerine, or a mixture
To use, put a tablespoon or so into the wash cup of your dishwasher. I don’t put it into the pre-wash cup, since that gets wasted.
From my calculations:
Homemade costs about 8 cents a load
Cascade at 22 cents a load
From the website: I have also started putting some of this in a shaker canister–the one I have we got at a restaurant supply, it’s aluminum and was made for popcorn salt. I use it to clean my sink and anything else that I’d normally use Bon Ami on. Works great, and the essential oil makes it smell fantastic.
