HOW TO FIX A STINKY SINK
How to Eliminate Kitchen Sink Odors and Drain Odors
Even if your sink isn’t clogged, there may be grease, food, or other debris attached to the walls of the drain. Here are a couple of simple ways to remove gunk and unwanted odors:
Add 2 cups of salt to 2 liters of boiling water, and stir until dissolved. Pour the boiling salt water down the drain. This will dissolve and flush out greasy residue, helping to eliminate kitchen sink odors.
Pour 1 cup baking soda and 1 cup white vinegar down the disposal. Let the mixture bubble for up to 10 minutes. Then pour a pot of boiling water down the drain to flush out the mixture. This will help break up smelly gunk and rinse it away. Remember, only run cold water when using your garbage disposal as this helps cool the motor.
