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 clearing loose hair first, then using the mixture to dissolve light soap scum and biofilm. Most slow drains are caused by hair mixed with soap, which forms a paste that mild acids help loosen but do not cut through heavy tangles. If the drain keeps slowing afterward, technicians who serve the Leo-Cedarville area can diagnose the line and present repair or cleaning options.

• Prep: Remove the stopper, pull out visible hair, and rinse with hot water.
• Apply: Pour about 1/2 cup baking soda into the drain, then 1 cup white vinegar.
• Wait and flush: Cover for 10–15 minutes while it foams, then flush with very hot water; repeat once if needed.
• Stop and escalate: If water still pools, avoid harsh chemicals and consider professional cleaning (cabling or jetting) to clear dense buildup.

Use a mesh hair catcher and clean the stopper monthly to prevent new clogs. <br/> Updated: 2026-04-11 <br/> Need help in Leo-Cedarville, IN? Call 833-498-7951 or book online. "He explained and fixed our clogged drain lines, and explained prevention in future." — Mike H.
