Garbage disposals have to do a lot, and its no surprise that they periodically need to be cleaned. Luckily, doing so is super easy and quick. Here's how you do it:
Pour half a cup of baking soda down the disposal, then pour a full cup of white vinegar on top of it. This will make it all fizzy sounding, which is normal. Let it sit for a couple minutes. In the mean time, go boil a kettle or pot of water. Once it is boiling, pour the water down the sink. This helps get things loose easy to clean off.
After that, put two drinking glasses of ice down the disposal. Then grab rock salt (normal salt will work, just not as well) and put it over the ice. Turn the sink's water on and turn the disposal on. Keep the disposal on until you can't see the ice anymore. This gets the gunk off of the blades of the disposal.
After that, keep running the water and the disposal and get the citrus of your choice, a lemon, orange, or lime, and put them down the sink. This helps deodorize your now clean sink!
