Deodorize the Dishwasher With Leftover Citrus Peels
You can do all kinds of cool things with citrus peels other than throwing them away. Next time you peel an orange, lemon, or grapefruit, put it in the dishwasher.
Citrus peels are great for all types of cooking, but they can also make great deodorants for things like refrigerators and trash cans . You can even use them in the dishwasher. Simply drop them (the rind and all the pulp) into the silverware strainer and start a normal cycle with any load of crockery ready to be washed. Citrus fruits will break down plaque inside the dishwasher and get rid of unpleasant odors. As a bonus, citric acid will also help clean glassware.
