⚡ Fastest Way to Unclog a Drain Naturally

1. Pour 3 cups of boiling water into the drain.
2. Add 1/2 cup baking soda and let sit for 5 minutes.
3. Mix 1 cup vinegar with 1 tbsp salt, pour into drain.
4. Cover with a plug or plate to trap the fizz.
5. Let sit 15–30 minutes.
6. Flush with another 3 cups of boiling water.

🛒 Ingredient Notes

• Baking Soda: Breaks down grime and neutralizes odor
• White Vinegar: Reacts to lift blockages via bubbling action
• Salt (optional): Scrubs and softens grease buildup
• Boiling Water: Flushes debris clean through the pipe

🔬 How It Works

When baking soda and vinegar combine, they create a fizzy chemical reaction that pushes built-up sludge, soap scum, and organic material through your pipes. Salt acts as a gentle abrasive, helping to break down fatty deposits. Finally, boiling water melts and flushes any remaining debris, restoring flow—without harsh chemical residue.

4. In a measuring cup, combine 1 cup vinegar and 1 tbsp salt.

5. Pour the mixture into the drain. Quickly cover with a plug or plate.

7. Finish by pouring the remaining boiling water down the drain to flush.
