Even though the garbage disposal is designed to pulverize and remove kitchen waste from food products, food particles often become trapped in the nooks and crannies of the disposal and drainpipe. Bacteria can then grow and create unpleasant odors! If you think (or even feel) that your garbage disposal isn’t as fresh as it should be, DIY these homemade refreshers for a quick fix. There are lots of ideas for anyone but the most common ingredients are fresh citruses, baking soda, essential oils, dish or castile soap and salt because they help to neutralize bacteria and smells. Read the tutorials below and choose the recipe that suits you.
