They are often safer for your pipes and the environment than harsh supermarket chemicals. Baking Soda & Vinegar: This classic combo works by creating a chemical reaction that can eat through minor organic clogs. Pour a pot of boiling water down first. Add 1 cup of baking soda, followed by 1 cup of vinegar. Cover the drain for 10–20 minutes, then flush with more boiling water.
