Washing dishes with baking soda
I forgot to buy dishwasher detergent, and I discovered this when the dishwasher was full. So I Googled dishwasher detergent substitute and learned you can put baking soda in the dispenser. I did so--about three heaping teaspoons--and ran the usual wash cycle. The dishes came out sparkling.
This makes me wonder if there's a reason why we need to use dishwasher detergent.
PS: Interestingly, the glassware came out exactly the same as when I use Cascade gel: some perfectly clear, and some covered in a white powdery coating.
