Mix 1/2 cup of salt with 1/2 cup of baking soda. Pour the mixture directly into the clogged drain and let it sit for 10-15 minutes.
Add Boiling Water
Slowly pour a pot of boiling water down the drain. The heat combined with the salt and baking soda will help break down the clog.
Add Vinegar (Optional)
For tougher clogs, pour 1 cup of white vinegar down the drain after the boiling water. The vinegar will react with the baking soda to create a fizzing action that can further loosen the blockage.
Flush with Boiling Water Again
Pour a second pot of boiling water down the drain to flush away any remaining debris.
