Can You Go Through a Car Wash with a Cracked Windshield?

Can You Get a Car Wash with a Cracked Windshield?

Technically, yes—you can. But it's not always wise.
Even a small crack weakens the structural integrity of the glass. The pressurized water in an automatic wash can cause the crack to expand or splinter across the windshield.

Here's why:

• High-pressure jets can push water into the crack, creating internal stress.
• Rotating brushes can vibrate the glass or catch an edge of the crack.
• Temperature swings from hot water or air dryers can make the glass flex.

Structural weakness increases dramatically once cracks appear—especially if they're longer than 6 inches or near the edge of the windshield.

If you absolutely must wash your car, skip the automatic tunnel and opt for a gentle, touchless or hand wash instead.

Types of Car Washes and Their Impact on Cracked Glass

Not all car washes are created equal. Here's how different methods affect a cracked windshield:

When Is It Safe to Wash Your Car After a Windshield Replacement?

If you've recently replaced your windshield, it's important to wait before washing your car.

Windshield adhesives need 24–48 hours to fully cure and bond. Washing too soon—especially with high-pressure water—can weaken the seal or cause leaks.

Here's what to do instead:

• Gently wipe away dust using the AutoManiacs Drying Towel (1500 GSM, ultra-absorbent).
• Avoid slamming doors for the first day—pressure changes can shift the seal.
• Park in the shade to let the adhesive cure evenly.

Once the waiting period has passed, you can safely return to your normal wash routine.

DIY Cleaning Tips While Waiting for Repairs

Just because you're skipping the car wash doesn't mean your car has to look neglected.

How to Prevent Future Windshield Damage

Once your windshield is repaired or replaced, prevention is the key to keeping it crack-free.

• Avoid drastic temperature changes. Don't blast the defroster on a freezing windshield.
• Keep a safe following distance. Rocks and debris from other vehicles cause many windshield cracks.
• Use the right cleaner. Harsh chemicals or ammonia-based sprays can degrade the glass seal—stick with AutoManiacs Ceramic Glass Cleaner for a streak-free finish and hydrophobic layer.
• Inspect regularly. Small chips can often be repaired before they become major cracks.
