A scratched windshield might not seem like a big deal, until sunlight hits it just right, or your wipers make it worse. Scratches on your windshield can reduce visibility, cause glare at night, and even weaken the integrity of the glass over time.
The good news? Many windshield scratches can be repaired with the right tools, techniques, and a bit of elbow grease. In this guide, we’ll explain what causes windshield scratches, how to repair them yourself, when to seek professional help, and how to prevent future damage.
What Causes Windshield Scratches?
Your windshield is exposed to a lot, and even everyday driving can leave marks. Common causes of windshield scratches include:
- Worn-out windshield wipers rubbing metal against the glass
- Debris (like sand or dirt) trapped under wiper blades
- Automatic car washes with abrasive brushes
- Improper cleaning tools, like paper towels or dry scrubbing
- Accidental contact with keys, tools, or ice scrapers
Over time, these small abrasions can add up—especially if left untreated.
Types of Windshield Scratches
Not all scratches are equal. Identifying the type of scratch you’re dealing with will help you choose the right repair method.
1. Light Surface Scratches
- Shallow marks that don’t catch your fingernail
- Often caused by dirty wipers or improper cleaning
- Usually cosmetic but can reflect light
2. Moderate to Deep Scratches
- Deeper grooves that may catch your fingernail
- Can interfere with visibility or weaken the glass
- May require professional repair or more aggressive polishing
3. Cracks and Chips (Not Scratches)
- A chip or crack is a structural break in the glass
- These require different repair methods—read our Windshield Crack Repair Guide for help
Can You Repair a Scratched Windshield?
Yes, but it depends on the depth and location of the scratch.
- Shallow scratches are often repairable with DIY methods or commercial polishing kits.
- Deeper scratches, especially those in the driver’s line of sight, may require professional repair or even replacement if they pose a safety risk.
Pro Tip: The sooner you address a scratch, the easier it is to fix.
DIY Windshield Scratch Repair Methods
If you’re dealing with surface scratches and want to try fixing them at home, here are the most popular and effective methods:
1. Glass Polishing Compounds (Cerium Oxide)
Cerium oxide is a fine powder often used by professionals to polish glass.
How to use:
- Clean the windshield thoroughly.
- Mix cerium oxide with water to form a paste.
- Apply the paste with a polishing pad or felt disc attached to a drill.
- Work the compound in circular motions for a few minutes.
- Wipe clean and inspect the area.
This method works best on light to moderate scratches.
2. Toothpaste or Baking Soda (Quick Fix)
These household abrasives can help minimize very light scratches.
Instructions:
- Mix a small amount of non-gel toothpaste or baking soda with water.
- Rub gently over the scratch using a microfiber cloth in a circular motion.
- Rinse and inspect.
⚠️ This is a temporary fix and mostly cosmetic. It won’t help with deeper scratches.
3. Windshield Scratch Repair Kits
Available online or at auto parts stores, these kits usually include:
- Polishing compound
- Applicator pads
- Microfiber cloths
- Instructions
Benefits:
- Specifically formulated for automotive glass
- More effective than household items
- Ideal for beginner DIYers
Look for kits that include cerium oxide or similar polishing agents for best results.

Should You Repair or Replace the Windshield?
Here’s how to decide:
| Condition | Recommendation |
| Light, surface scratches | DIY repair or polishing kit |
| Deep scratches in driver’s view | Professional polishing |
| Long, deep scratches or multiple areas | Consider replacement |
| Scratches that have become cracks | Replace the windshield |
Rule of thumb: If a scratch can’t be repaired without impairing visibility, it’s safer to replace the glass.
