As the summer heat intensifies, it’s important to pay attention to the condition of your vehicle, particularly your windshield. That’s because things like extreme temperatures and road debris can take a toll on your windshield, making it more susceptible to cracks or chips. 

Even small chips and cracks can eventually lead to  consequences that can go beyond an inconvenience. A cracked windshield can reduce visibility, which is critical for safe driving. It can also impair the structural integrity of your vehicle, making it more vulnerable to damage in the event of an accident. In some cases, the damage might be severe enough to require a complete windshield replacement, which can be both costly and time-consuming.

Fortunately, with a few preventive measures, you can protect your windshield from the heat and ensure its longevity throughout the season and beyond. Here are some essential summer windshield care tips to help keep your glass in top shape.

1. Repair Any Existing Damage Promptly

One of the best ways to prevent your windshield from getting worse during the summer is to repair any existing damage as soon as possible. Small chips or cracks may seem harmless at first, but the extreme summer heat can cause them to expand quickly. The pressure from the heat causes the glass to expand, and once there’s a crack or a chip, it’s likely to worsen.

If you notice any damage, get it expertly repaired before the temperatures soar. Professionals have the tools and expertise to assess the extent of the damage and provide the appropriate solution, whether it’s a simple repair for minor chips or a full replacement for larger cracks. If you live in Ontario, California, or any of its nearby communities, a quick online search for “auto glass repair in Ontario CA” can help you find various professional services that can fit the bill. 

2. Park Your Car in the Shade

When you park your car in direct sunlight, it can heat up the interior and harm your windshield. As mentioned previously, heat expands the glass, which increases the likelihood of cracks forming. Additionally, the sun’s UV rays can weaken the glass over time.

To prevent this, always try to park your car in the shade. Whether it’s under a tree, in a parking garage, or using a carport, shade can help keep your windshield cooler.

3. Avoid Extreme Temperature Changes

Sudden temperature changes can also be hard on your windshield. For instance, when you turn on the air conditioning in a hot car, the cold air can cause the glass to contract, while the heat from the outside causes it to expand. This sudden change in temperature puts stress on the glass and can lead to cracks.

If you want to prevent this kind of issue, try to avoid cranking the air conditioning up immediately after getting into a hot car. Instead, let the vehicle cool down gradually before adjusting the temperature. This will allow the windshield to adjust to the changing environment more slowly, reducing the likelihood of thermal stress.

4. Be Cautious When Washing Your Car

Washing your car can help maintain its appearance. However, you must be careful when it comes to cleaning your windshield during the summer. Using extremely hot or cold water on your windshield can cause thermal shock, which leads to cracks.

So, avoid exposing your windshield to rapid temperature change. This means you should wash your car during cooler hours, such as early mornings or late evenings, when the temperature is lower. Also, be sure to use lukewarm water and avoid spraying cold water directly on the hot windshield. Make sure to use soft microfiber towels or a gentle cloth to clean the surface, as abrasive materials can scratch and weaken the glass.

5. Maintain a Safe Distance to Prevent Road Debris

Driving behind large vehicles like trucks, buses, or construction vehicles can also expose your windshield to road debris, such as rocks, gravel, or dirt. These small projectiles can easily chip or crack your windshield, especially when traveling at high speeds.

To minimize this risk, always maintain a safe distance from larger vehicles. Giving yourself enough space allows you to react in case of debris on the road. Additionally, if you notice a construction zone or a particularly dusty road, slow down and be extra cautious.

6. Use a Windshield Protector or Cover

During peak summer months, the sun can be harsh on your car’s windshield, which can lead to potential damage from UV rays and extreme heat. A simple yet effective solution is to use a windshield protector or cover. These are designed to shield your glass from the sun’s harmful effects and reduce the heat buildup inside the car.

Windshield covers are available in a variety of materials, including reflective ones that block UV rays. This extra layer of protection can help keep your windshield from overheating and protect it from any potential damage caused by exposure to direct sunlight.

Taking care of your windshield during the summer is crucial. Consider following these simple tips to significantly reduce the risk of cracks and heat damage. Moreover, don’t wait for your windshield to develop major issues. Stay proactive, and protect your windshield with a little extra care this summer. After all, a well-maintained windshield isn’t just about aesthetics—it’s about ensuring clear visibility and the safety of everyone in the car.
