I've used homemade dishwasher detergent also, and while it worked pretty well, I found that the savings wasn't nearly as great as with laundry soap, and the product just didn't work quite as well either. So since I usually buy dishwasher detergent, I try to make sure I get the best bang for my buck.
These two Cascade products are priced the same: 20 count packs and 75 ounces of liquid gel.
The packs are so handy...no mess, no squeezing. But I was always pretty sure that they were overpriced compared to the gel. To confirm my suspicions, we kept a tally every time we used the gel. And the verdict? 45 washes!
I think I am completely cured of my desire to buy those cute little packs from here on out! And I think this little experiment helped me to be a more active consumer of the products that I am choosing to purchase.
I think I'm going to have to test the powdered dishwasher soap next and compare that to the gel
