Tips to Prevent Car Glass Scratches
Preventing scratches is always better than repairing them. Here are some simple tips:
Regular Cleaning
- Wash your windshield and windows regularly to remove dust and grit.

Conclusion
Removing car glass scratches at home is possible with the right methods and tools. Simple solutions like toothpaste and baking soda work for light scratches, while cerium oxide or commercial kits are better for moderate damage. Sandpaper is an option for advanced DIYers but requires caution.
