A warm weekend is the perfect time for a car wash! But what if your windshield or window has a crack? Before you grab the hose or head to the car wash, it’s worth asking whether washing your car could actually make the damage worse. Here’s what you need to know before you get started.
Is It Safe to Wash a Car with Cracked Glass?
Sometimes it’s fine, but not always. A small chip might not cause any trouble, but larger cracks or existing damage can get worse during a wash, especially with high-pressure water or sudden temperature changes.
A few things to watch out for:
- Water pressure: Automatic car washes use strong jets of water, and that can be tough on cracked glass. If your window or windshield already has damage, the pressure might cause the crack to grow or spread.
- Temperature shifts: Pouring hot water on a cold windshield, or cold water on a hot one, can stress the glass. Sudden temperature shifts can make existing cracks expand, especially on days with changing weather.
- Soap and tools: Most soaps are gentle enough for cracked glass, but rough brushes or abrasive tools can snag on damaged areas and cause additional harm.
- Weakened glass: Cracked glass is more fragile than it looks! Even if it holds up during the wash, it may be more likely to break under pressure later on. Water can also seep into the crack and get trapped, which can cause the damage to spread over time.
What If You Still Want to Wash Your Car?
If the crack is small and hasn’t changed, you might be able to wash your car very gently, but only as a short-term workaround. Keep in mind that even a careful wash carries some risk.
Here are a few safer ways to clean your car in the meantime:
- Wash by hand with caution
Use mild soap and a soft stream of water. Avoid scrubbing or spraying near the cracked area. - Wipe around the damage
If you’re unsure, it’s best to clean around the crack and leave the damaged glass alone until it’s repaired. - Repair first whenever possible
This is the best way to protect your glass and avoid more costly damage. Temporary workarounds may help for now, but a professional repair is the most reliable long-term fix.
