To use, put a tablespoon or so into each cup of your dishwasher. I've found I no longer have to use the scrubbing cycle but can get by fine with the short cycle, thus saving even more money. On average, it looks like this is about 8 cents a load compared with Cascade at 22 cents a load. Compare it with EcoVer or Seventh Generation and it's a steal. 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.I have used this recipe as well and I like it a lot for washing dishes. I think the salt adds an abrasive that helps get things clean.
In a plastic container with a firmly fitting lid, mix:
1 cup borax (20-Mule-Team Borax, available in any supermarket)
1 cup baking soda
1/4 cup salt
1/4 cup citric acid (available in brewing stores among other places--if you haven't tracked it down yet but must try this formula, use two packets of Lemonade-Flavored Kool-Aid, ONLY lemon, or you'll dye your dishwasher! and ONLY unsweetened Kool-Aid!)
30 drops citrus essential oil--lemon, grapefruit, orange, tangerine, or a mixture
Put all of it in the container, shake it up.
