Natural cleaning methods for a clogged sink, such as pouring boiling water down the drain or mixing white vinegar and baking soda to create a cleansing volcano of carbon dioxide, have been circulating on the internet since the days of dial-up connections. They often work, but only for clogs that you could probably easily clear by plunging. Regularly add boiling water with a grease-fighting dish soap down the drain to prevent the buildup of greasy clogs. Freshen your drains by adding 1/2 cup of baking soda to the drain and allowing it to sit overnight, then flushing with hot water
