Gargling with salt water several times a day is an effective treatment for chest congestion. While the salt helps remove mucus from the respiratory tract, the hot water reduces irritation in the throat. 1  Add 1 teaspoon of salt to a glass of warm water.  Mix well until the salt is dissolved thoroughly.
Gargle. A good gargle is one of the best remedies for chest congestion. It can break up the mucus that causes congestion and get rid of the inflammation that worsens congestion. 1  Stir 1 teaspoon of salt into 1 cup of warm water until it dissolves. 2  Tip your head back, pour the water in, and gargle for at least 30 seconds.
