How Can I Fix a Slow Shower Drain Using Baking Soda and Vinegar?

You can fix a slow shower drain with baking soda and vinegar by removing the stopper, clearing visible hair, then using the fizzing reaction to loosen soap scum before flushing with hot water. The most common cause is a hair-and-soap mat just below the stopper or in the P-trap.

Many slow drains respond to a simple physical clean plus this mild chemical reaction, but heavy root intrusion or a collapsed line needs a pro. We regularly help homeowners in Northern Colorado with drains that keep slowing down even after DIY attempts.

Try these steps in order:

• Pull the stopper and manually remove hair from the crossbar and trap.
• Pour 1/2 cup baking soda, then 1/2–1 cup plain white vinegar; let it work 10–15 minutes.
• Rinse with hot (not boiling) water; repeat once if needed.
• If still slow, use a plunger or a plastic hair snake before calling a pro.

Avoid mixing this method with chemical drain openers, and stop if water won’t drain at all. <br/> Updated: 2026-05-05 <br/> Need help in Kersey, CO? Call (970) 444-5951 or book online. "Chuck and his partner did most excellent work fixing a clog on a Friday evening!" — Coy A.
