How to Unclog a Sink Naturally with Baking Soda and Vinegar: A Proven DIY Method

Living in an old building means dealing with clogged sinks at least once a month. I've faced three water damages and countless overflows from blocked pipes in sinks, showers, bathtubs, and toilets—all due to pipe blockages.

Thankfully, after years of trial and error, I've discovered a highly effective, plumber-free solution: a simple mixture of baking soda and white vinegar. It's quick, safe, and backed by basic chemistry. Here's how it works.

What You'll Need

How to Unclog a Sink Naturally with Baking Soda and Vinegar: A Proven DIY Method

  • 100 g baking soda (about 1/2 cup)
  • 150 ml white vinegar (about 1/2 cup)
  • 1 basin of boiling water

Step-by-Step Instructions

  1. Pour 1/2 cup of baking soda directly into the drain.
  2. Add 1/2 cup of white vinegar on top.
  3. Quickly cover the drain with a stopper to contain the fizzing reaction.
  4. Let it sit for 30 minutes to break down the clog.
  5. Flush with a basin of boiling water to clear everything away.

The Results

Your sink is now clear! This method is easy, fast, and reliable—saving you from costly plumber visits. Plus, baking soda and vinegar are affordable, 100% natural, and eco-friendly alternatives to harsh chemical cleaners like Drano that pollute waterways.

A quick tip: Avoid pouring food scraps down the drain to prevent future clogs.

Why It Works

The baking soda (a base) and vinegar (an acid) react to produce carbon dioxide gas, creating foam that dislodges grease and organic buildup. Boiling water then melts away any remnants, ensuring smooth flow. It's a safe, science-based remedy with no risk to pipes or health when used as directed.
