What do you combine with baking soda boiling water to unclog a sink drain?
Pour 1/2 cup of baking soda down the drain followed slowly by white vinegar. It will foam and bubble. Let it sit about 5-10 minutes, then flush the drain with hot water. It will also remove odors from the drain. This works best in a kitchen drain that is running slow, not completely stopped up. I don’t think it works as well on hair clogs.
