OUT OF DISHWASHER DETERGENT? NO PROBLEM!
If you've run out or can't find dishwasher detergent, have no fear! You can make your own.
Mix two teaspoons of regular dish soap and four teaspoons of baking soda in a bottle of water and you're good to go! (Note: you may have to play with the amount of each ingredient a bit depending on your dish soap, bottle size, etc)
