If you’ve ever had coffee that’s burnt on the bottom of your glass coffee pot, or if the coffee has started to form a film on the top of the pot, then it’s time to clean it. The first step is to take off the pot and place it in a bowl. Pour out all of the coffee that’s in the pot and add water to cover. Bring the water to a boil and then turn off the heat. Pour this hot water over the burnt coffee and let it sit for 10 minutes. Next, take off any excess plastic wrap that’s been around the pot. Place this over top of the coffee and let it sit for another 10 minutes. Finally, use a cloth or a spoon to remove all of the burnt coffee from around the pot.
