At Rite-Way Auto Glass, our generational, family-owned business is committed to helping drivers maintain their vehicles continuously for the safety of everyone on the road. So, we’ve put together this step-by-step guide on how to clean sunroof drains.
Understanding Sunroof Drains
Let’s start with the basics. Sunroof drains have one primary purpose: to move water away from the sunroof frame and out of your vehicle. With proper maintenance, debris won’t accumulate in your car, even during the heaviest rains.
Common Causes of Clogged Sunroof Drains
Your sunroof drains don’t just clog out of the blues. Usually, it’s because debris and dirt buildup cause blockages as they accumulate over time. Moreover, leaves, twigs, and wildlife components can also build up in the drains.
Check regularly for any clogs in the drains to avoid further issues. It’s easier to clear out a small blockage than to tackle a much larger one.
Remember, these car parts are often under high exposure to natural elements. So, avoid corrosion and rusting by routinely cleaning and inspecting your sunroof drains.
Consequences of Neglected Sunroof Drain Maintenance
It’s always best for your pocket and car interior to perform sunroof drain maintenance. If ignored, clogged drains can cause water damage inside the vehicle and even mold growth.
Additionally, if you keep driving with a blocked sunroof drain, it could eventually cause the roof to cave in due to structural corrosion. So, acting fast when you notice blockage signs in your car’s drainage system is essential.
Signs of Clogged Sunroof Drains
Here are some signs that may indicate your sunroof drains are clogged:
1. Water Leaks Inside the Vehicle During Rain or Car Washes;
These water leaks indicate that your sunroof drains are blocked and water isn’t flowing away from the sunroof as it should.
2. Damp or Musty Odor Inside the Car;
Do you keep picking up a musty smell in the car? That’s a sign of mold or mildew, likely caused by standing water.
3. Wet Carpets or Upholstery;
Where’s the water coming from, if not from the roof? You guessed it: your clogged sunroof drains.
The Tools and Materials You Need To Clear A Clogged Sunroof Drain
Cleaning a clogged sunroof drain requires skills and the rite-tools. You’ll need the following sunroof drain cleaning tools:
- Clean rags or towels;
- Compressed air canister or air compressor;
- Flexible wire or coat hanger;
- Mild detergent or glass cleaner; and
- Water.
A Step-by-Step Guide to Cleaning Sunroof Drains
Let’s go over the steps for successful sunroof drain cleaning from start to finish.
Step 1: Preparation
- Park your vehicle on a flat surface;
- Ensure the sunroof is closed correctly; and
- Gather the necessary tools and materials.
Step 2: Locating the Sunroof Drains
Sunroofs usually have two drainage openings: one at the front corner and another at the rear corner of the sunroof. You first need to locate the edges of your sunroof frame to identify these drains.
The drain openings should be visible if you look closely. Just open the sunroof, then take your time, and look carefully.
Step 3: Clearing Debris from the Drain Openings
Sunroof drains are narrow and can be challenging to clean. A regulated air pressure tool can help clear debris from the drain openings.
Use compressed air or an air compressor to blow air into the drain openings. It will force all the debris within the drains to move out the other end.
The Importance of Eye Protection When Cleaning a Clogged Sunroof Drain
It’s essential to wear eye protection when you’re cleaning debris from the sunroof drains. Flying particles, dust, and anything else blown out by the air compressor can cause serious injury if it gets into your eyes.
Avoid Using Excessive Air Pressure To Unclog Your Sunroof Drain
The intricate components of the sunroof drainage system can easily incur damage if you use too much air pressure when unclogging them. Using enough pressure to remove debris from the drains without causing long-term damage is best.
From experience, we find that exceeding 30 psi is too much for most sunroof drain systems.
Step 4: Flushing All the Sunroof Drains
Mix a mild detergent or glass cleaner with water and pour the solution into the sunroof drain openings. Allow the solution to flow through the drains and clean any remaining debris.
Flushing ensures that no particles remain in the drainage system, which can lead to further blockages later. Using detergent removes greasy or oily substances from the drains but must be mild enough to avoid corrosion damage.
Step 5: Removing Stubborn Clogs
Sometimes, debris is stuck in the drains and won’t budge. If this happens, gently dislodge the particles using a flexible wire or coat hanger. However, caution against excessive force during this process as it can damage the drainage system.
The flexible wire you use needs to be long enough to reach from the drain opening to the end of its channel. Also, ensure you don’t bend or break anything along the way.
Then, flush the sunroof drains one more time. Use a mixture of clean water and mild detergent to ensure no debris remains in the system.
Step 6: Final Checks and Maintenance
It would help if you did some final checks once all the above steps are complete. Inspect all the sunroof drains for any clogs or obstructions. Test them by pouring water into the sunroof channel to ensure they’re draining correctly.
