How Do You Clean an Old Bathtub Drain?

Published in Drain Cleaning 3 mins read

Clean out your old bathtub drain effectively using a simple, natural method that helps clear buildup and tackle odors with common household ingredients.

Step-by-Step Drain Cleaning Method

A reliable way to clean an old bathtub drain, as outlined in practical home maintenance tips, involves a four-step process using boiling water, baking soda, and vinegar.

Here are the steps to follow:

  1. Pour Hot Water: Begin by carefully pouring a pot of boiling water directly down the bathtub drain. This helps to loosen any initial grime or debris that may be present.
  2. Add Cleaning Mixture: Next, pour a mixture consisting of one cup of baking soda followed by one cup of vinegar into the drain opening.
  3. Seal and Wait: Quickly insert the drain plug or close the filter mechanism to contain the reaction within the drain. Let the mixture work for approximately 5–10 minutes.
  4. Final Flush: After the waiting period, flush the drain again by pouring another pot of boiling water down it to rinse away the loosened materials.

The Science Behind the Clean

This method is effective due to the properties of the ingredients used:

  • Boiling Water: High temperatures help to melt or soften grease and soap scum that commonly contribute to drain blockages and foul odors.
  • Baking Soda and Vinegar: When baking soda (a base) mixes with vinegar (an acid), a chemical reaction occurs. This reaction produces carbon dioxide gas, causing fizzing and bubbling. This effervescence helps to dislodge blockages and scrub the inside of the drain pipes.

Combining the physical action of hot water with the chemical reaction of baking soda and vinegar provides a powerful, non-toxic way to clean and refresh your old bathtub drain.

For a quick overview, here are the essentials of this cleaning method:

Step Action Ingredients/Tools Wait Time
