Measure a half cup of baking soda and pour it down the clogged pipe’s drain opening.
Measure a half cup of household vinegar and pour it down the drain after the baking soda. Cover the drain opening and wait 30 minutes.
Boil a pot of water while waiting. After 30 minutes, pour the hot water down the drain to flush the solution through the clogged pipes and dislodge the obstruction.
Test the water flow. Repeat the process as necessary. After the clog has been cleared, you may want to repeat the process once a week to ensure that the pipes stay unclogged.
