Unstopping a Clogged Drain 1/4 cup baking soda 1 cup white vinegar 1 large pot of boiling water (I removed my pop-up drain stopper first.) Carefully pour the baking soda down the drain. Follow with 1 cup of white vinegar. Let it stand for about 15 minutes. Then I poured a pot of boiling water down the drain
Tip: Once a week, toss in a few frozen cubes of white vinegar and turn on your disposal. The vinegar will get in all the moving nooks and crannies that are otherwise hard to get to and the ice will sharpen your blades.
