DIY Cooling Care: How to Effectively Clean Your AC Drain with Vinegar

Cleaning your air conditioning (AC) drain line with vinegar is a simple yet effective way to maintain the efficiency and functionality of your AC unit.

Over time, dust, debris, and algae can accumulate in the drain line, leading to clogs and potential water damage. Fortunately, using vinegar as a cleaning agent can help dissolve these blockages and prevent costly repairs.

In this guide, we’ll walk you through the steps to clean your AC drain line with vinegar, ensuring that your system operates smoothly and keeps your indoor space cool and comfortable.

How Much Vinegar Do I Need To Clean AC Drain Line?

To clean an AC drain line, you will need approximately 1 cup of vinegar. Pour the vinegar into the drain line and let it sit for 30 minutes.
