How you maintain your auto glass following a windshield replacement has a major effect on the longevity of your windshield. 

After replacing your windshield, give it time to set properly. The installation uses a strong adhesive to form a watertight seal. Whether the replacement is done at your home or at a shop, you should wait at least an hour before using your vehicle to ensure the adhesive has begun to set.

Here are some additional tips on windshield replacement aftercare to ensure that your new windshield maintains its integrity and performance.

What To Do After Windshield Replacement: The First 48 Hours

Your windshield is most vulnerable to damage during the first 24-48 hours following your windshield replacement service. This is because the adhesive used to install your windshield needs time to cure fully. 

It’s important to follow these windshield replacement aftercare tips to ensure the longevity of your newly replaced auto glass. 

Leave the Side Windows Open 

When your car windows are completely closed, air pressure builds up inside, potentially stressing the windshield’s adhesive seal and causing leaks. To maintain the seal’s integrity, keep the side windows slightly open for at least two days to release hot air and prevent excessive pressure.

Park in a Covered or Shaded Spot 

Exposing your vehicle to direct sunlight and other extreme weather conditions like rain or strong winds can affect the adhesive’s curing process. To avoid this, it’s best to park your car in a garage or a shaded, covered location for at least 48 hours. 

Avoid Getting a High-Pressure Car Wash

Although it can be tempting to pair a newly replaced windshield with a clean car, auto glass experts would typically advise against getting a car wash, especially a high-pressure wash, in the first 48 hours following your windshield replacement.

High-pressure washers can weaken the bond, risking cracks or detachment from minor impacts.  Additionally, harsh detergents can also damage the adhesive. 

If you need to wash your car after a windshield replacement, opt for a gentle hand wash with a mild detergent or a light spray from a hose. Additionally, hold off on car detailing or wax treatments to ensure the adhesive cures properly without disturbance.

Do Not Remove the Retention Tape 

After getting your windshield replaced, you may be wondering how long you should leave the tape on after windshield replacement. Retention tape is not just for holding the mouldings in place; it also supports the newly applied adhesive under the windshield, helping it cure in the correct position without external pressures or contaminants like dust and water.

Typically, the retention tape should be left on for at least 24 to 48 hours. This period allows the adhesive to dry and cure sufficiently, ensuring a strong, watertight seal between the windshield and the frame of your vehicle. Removing the tape too early can lead to shifts in the windshield’s position or introduce particles that could weaken the bond.

Don’t Drive in Heavy Rain 

Driving in heavy rain soon after replacing your windshield can be problematic because the water can interfere with the curing process of the adhesive used to secure the windshield. When the adhesive is not fully set, water can seep under the windshield, potentially weakening the bond with the vehicle’s frame. 

This can result in leaks, and in some cases, the windshield may even become dislodged. Moreover, the pressure from heavy rain can stress the newly installed glass, increasing the risk of misalignment or damage. As much as possible, it’s best to avoid driving your vehicle in heavy rain after a windshield replacement. 

Avoid Using Windshield Treatments

While Rain-X Water Repellent and similar treatments are popular among drivers, it’s important to wait for at least 48 hours before applying the treatment. Applying these treatments directly after a windshield replacement can interfere with the adhesive’s curing, resulting in a compromised seal.

Guide to Long-Term Windshield Maintenance

Long-term maintenance is crucial for windshields because it not only extends their lifespan but also ensures optimal visibility and safety while driving. Here are some tips on how to maintain your windshield better:

● Clean your windshield regularly using a high-quality glass cleaner and a microfiber cloth. This helps prevent dirt and residue build-up, which can obscure your view and potentially cause scratches when wipers are used.

● Address any chips or cracks as soon as they appear. Even small imperfections can quickly spread, especially with temperature changes or driving on bumpy roads. Early repairs can often be simple and cost-effective, preventing the need for a full windshield replacement.

● Replace your windshield wipers every six to twelve months or at the first sign of streaking or missed areas. Worn wipers can cause scratches on the glass surface and reduce visibility during adverse weather conditions.

● Regularly check the seals around your windshield for signs of wear or leakage. A compromised seal can allow water and moisture to enter, which can damage the interior of your vehicle and cause the windshield to become loose.

Indicators of an Improper Windshield Installation

While it’s important to follow aftercare tips, it won’t matter if the windshield installation was faulty. If you are experiencing the following after a windshield installation, then your auto glass may have been improperly installed: 

● Visible gaps between the glass and the vehicle frame: This indicates that the windshield is not sealed properly, which can lead to leaks and wind noise.

● Rattling sounds while driving: If you hear rattling, it may be due to the windshield not being securely fitted, which could cause further instability or breakage.

● Irregular patterns on the glass: This could suggest poor handling or installation techniques, resulting in stress points that could crack.

● Water leaks inside the vehicle: If water seeps into the vehicle during or after rain, this is a clear sign of a poor seal.

● Wind noise at high speeds: An increase in wind noise usually points to gaps or improper fitting around the windshield edges.
