How to Cure a Smelly Sink Drain
-Start with a clean, empty sink.
-Boil about 2 quarts of water.
-Once boiled, flush the drain by pouring the hot water down the drain all at once. (Please be careful. Do not dump the hot water in a way that it will splash and burn you.) This will melt and soften any grease that’s trapped.
-Add about 1 cup of baking soda to the drain. I just eyeball it. Then pour about 2 or 3 cups of white vinegar down the drain on TOP of the baking soda. (Also, fill the pot back up with water and return to boil).
-Let sit 5-10 minutes.
-Flush with the boiling water or run hot water for 1-2 minutes and allow to drain out. Rinse any leftover baking soda down with the hot water.
-To finish, flush with COLD water from the sink for 1-2 minutes, and then add 10-15 drops of Lemon essential oil. If you don’t have lemon oil, real lemon juice does the trick as well.
