Baking soda & vinegar flush

A simple pantry-staple method that helps loosen light drain buildup and deodorize pipes. Best suited for slow-running drains rather than full blockages.

Steps

1. Pour a full kettle of boiling water down the drain.
2. Add 1/2 cup baking soda and let it sit for a few minutes.
3. Pour in 1/2 cup white vinegar, then cover the drain opening.
4. Wait 10-15 minutes while the mixture fizzes.
5. Flush with another kettle of boiling water.

Tips

• The fizzing reaction produces CO2 gas, which looks dramatic but has limited mechanical force — it will not clear hair clogs or hardened buildup.
• Most of the benefit comes from baking soda acting as a mild abrasive and deodorizer.
• For stubborn or complete clogs, follow up with a plunger or drain snake.
• Avoid boiling water on PVC pipes — use hot tap water instead to prevent joint damage.
