Back here, the Old School discussed what happens when you use liquid dish soap in your dishwasher, and what to do to temporarily tide you over until your next trip to the market.
But is it possible to make your OWN dishwasher detergent? To use on a regular basis, not as an emergency substitute? Can you really unhook from the crazy that is the price of Cascade?
The Damsel is happy to inform that yes, you can easily make your own. As a matter of fact, the hardest part is trying to buy the ingredients: washing soda and borax. Apparently, these were pretty common items in the olden days, but are harder to find now.

Both of these items are considered laundry boosters, and generally that’s where you’ll find them at the store: in the laundry aisle. Borax is pretty easy to find. It’s the washing soda that’s tricky.

After sufficient sleuthing and you still come up empty, you COULD buy this. The ingredient is the same: sodium carbonate. The Damsel bought this at Wal-Mart in the pool/spa chemical aisle. However, it’s twice as expensive this way. $7 vs. $3.50.
If you’re interested in making other homemade cleaners as well, it’s worth it to keep hunting down the washing soda. It shows up in many cleaner recipes.
To make it, all you do is mix equal parts of washing soda and borax. The Damsel measured one cup of each into a container and stirred. That is all.

To use, try one tablespoon first and see how your dishes look. If you have a compartment that looks like this, fill the little side with the mixture and the big side with vinegar. This will help the glassware come out looking great.
The Damsel hesitates to give this an enthusiastic review. She’s only tried it once so far, and while most of the dishes looked perfectly clean, some didn’t. To be fair, she has extremely hard water and her dishwasher is trying to die. No dishwasher should have to work as hard as hers. She’s going to try it again, with a little more detergent and possibly adding the vinegar to the rinse cycle rather than in the dispenser. This will require more vigilance and hovering than she’s used to, but that is her plan.
