How to Keep a Cracked Windshield From Spreading: Preventing Further Damage
A cracked windshield is a serious issue, impacting visibility and potentially compromising the structural integrity of your vehicle. While immediate professional repair is always the best option, understanding how to temporarily manage a crack and prevent it from worsening can buy you time and potentially save you money. This guide explains how to keep a cracked windshield from spreading until you can get it professionally repaired.
What Causes Windshield Cracks to Spread?
Before we delve into prevention, let's understand the enemy: stress and vibration. Windshield cracks spread due to the constant pressure and vibration experienced during driving. Temperature fluctuations, impacts (even minor ones), and general road wear and tear all contribute to crack propagation. Understanding this is key to preventative measures.
How Can I Stop My Windshield Crack From Getting Bigger?
This is the million-dollar question, and the answer isn't a magic bullet. However, there are steps you can take to minimize further damage:
1. Clean the Crack:
Thoroughly clean the crack itself using a mild soap solution and a soft cloth. Dirt and debris trapped in the crack can exacerbate the problem and make it harder to repair later. This simple step can improve the efficacy of any temporary sealant you apply.
2. Apply a Temporary Sealant:
Several commercial products are designed to temporarily seal windshield cracks. These typically involve applying a resin to the crack, preventing further moisture ingress and reducing the likelihood of spreading. Follow the manufacturer's instructions carefully. These products are not a permanent solution but can offer considerable protection until professional repair is possible.
3. Prevent Further Impacts:
Avoid driving on rough roads whenever possible. Potholes and debris can significantly increase the stress on your already compromised windshield. Drive cautiously and smoothly to minimize vibrations.
4. Protect from Temperature Extremes:
Extreme temperature changes can put stress on the glass, potentially leading to crack propagation. Park your car in the shade during hot days and try to avoid exposing it to significant temperature swings. A sunshade can be helpful.
5. Avoid Washing Your Car:
High-pressure washing, especially near the crack, can force water into the crack, potentially leading to expansion. Avoid car washes until the crack is professionally repaired. A simple hand wash with low water pressure is fine, but steer clear of the damaged area.
What are the Signs a Windshield Crack is Getting Worse?
Keep a close eye on the crack. Watch out for:
- Increased length: A noticeable increase in the length of the crack is an obvious sign of propagation.
- Branching: New cracks emanating from the original crack indicate a worsening situation.
- Increased spiderwebbing: The area around the initial crack developing more small cracks.
- Change in appearance: The crack becoming wider or more pronounced.
Any of these signs warrants immediate action and you should seek professional repair as soon as possible.
Can I Drive with a Cracked Windshield?
Legality varies depending on your location and the severity of the crack. Generally, cracks that obstruct your vision or compromise the structural integrity of the windshield are illegal and unsafe to drive with. Even smaller cracks can become more significant quickly.
When Should I Get My Windshield Replaced?
If the crack is large, obstructs your vision, or significantly affects the structural integrity of your windshield, replacement is usually necessary. It's best to consult with an auto glass repair professional to assess the damage and recommend the best course of action.
By following these tips and remaining vigilant, you can significantly reduce the chances of your cracked windshield spreading and stay safe on the road. Remember, temporary solutions are just that—temporary. Professional repair or replacement is crucial for long-term safety and legal compliance.
