How to Clean a Sunroof Drain: Step-by-Step Guide
Step 1: Gather Your Supplies
Before you start, you’ll need:
- Compressed air can or air blower

Step 2: Locate the Sunroof Drains
Most cars have 4 drainage holes, located at:

Check your car manual if you’re unsure about the location.
Step 3: Remove Surface Debris

Step 4: Clear the Drain with Compressed Air
- Insert a compressed air nozzle or small air blower into the drain.

- Avoid using excessive pressure to prevent damage to the drain tube.
Step 5: Use a Flexible Wire or Pipe Cleaner

Step 6: Flush the Drain with Water
- Slowly pour warm water into the drain hole.
- Watch for water exiting near the bottom of the car.
- If the water doesn’t drain, repeat steps 4 and 5.
Step 7: Use Vinegar and Baking Soda for Deep Cleaning (Optional)
