Tired of persistent sewer smells rising from your kitchen sink? It's a common issue with frequent use, but harsh chemical cleaners aren't the answer—they're expensive and unnatural.
Instead, professional plumbers recommend a simple, time-tested remedy using baking soda and white vinegar to neutralize odors deep in the pipes. Here's how it works effectively.

- 250 g baking soda
- 250 ml white vinegar
1. Pour about 250 g of baking soda directly into the drain.
2. Add 250 ml of white vinegar.
3. Let it sit for 15 minutes.
4. Flush with very hot water.
This plumber-approved method quickly eliminates foul odors from your sink. It's easy, fast, and 100% natural, preventing clogs while thoroughly cleaning pipes.
It works on kitchen sinks (single or double), bathroom sinks, bathtubs, showers, and even bidets—no need for commercial odor removers.
Sewer smells often stem from bacterial buildup in pipes. Baking soda neutralizes odors by targeting those bacteria, while vinegar acts as a powerful disinfectant to clean the drain.
Their reaction creates a fizzing foam that dislodges stuck debris from the siphon and pipes. Hot water then rinses everything away for a fresh, clean result.
For ongoing prevention, pour 250 ml of white vinegar down the drain every night. Let it sit overnight, then use the sink normally in the morning. Repeat for a week for best results.
