People mix these up all the time. "My headlights are scratched" and "my headlights are cloudy"—for a lot of folks, it's the same thing. But they're two completely different problems with different causes and different solutions. Mixing them up can cost you time and money if you end up treating the wrong issue.
What's the difference?
A cloudy headlight is one where the plastic has undergone chemical oxidation caused by UV rays. The surface turns yellow, milky, hazy. It's uniform across the whole lens. Run your finger over it: it's rough but even. We break down this process in detail in our article about the causes of yellowed headlights.
A scratched headlight is one that's taken physical damage. Visible marks, scuffs, lines in the plastic. This can come from rocks kicked up on the highway, a brush-style car wash, or even aggressive cleaning with a dry cloth. Scratches are localized and uneven.
Do we treat them the same way?
Partially. Professional restoration can handle both, but the process is a bit different.
For cloudiness, sanding with medium-grit usually takes care of the oxidized layer. That's the easy part. Polishing brings back clarity and the protective coating seals the deal.
For scratches, it depends how deep they go. Shallow scratches (ones you can barely feel with your fingernail) come out with sanding and polishing. Deep scratches (ones your nail actually catches on) are tougher. They need more aggressive sanding with coarser grit and multiple refinement steps. Sometimes the deepest ones stay slightly visible even after treatment.
The fingernail test
Run your thumbnail perpendicular across the scratch. If your nail glides right over it without catching, that's a shallow scratch. Polishing will fix it. If your nail catches in the scratch and you feel it clearly, that's a deep scratch. You'll get a good result from polishing, but maybe not a perfect 100%.
Either way, even if the scratch stays slightly visible up close, it'll be way less noticeable and won't mess with light transmission. Your headlight will shine properly, and that's what matters.
How to prevent scratches
A few simple habits prevent most scratches. Never rub your headlights dry. Always rinse first to clear out abrasive particles. Use a microfiber cloth, not paper towels or an old t-shirt. And skip the automatic car washes with spinning brushes when you can.
A ceramic coating helps too. On top of protecting against UV, it creates a hard layer that resists everyday micro-scratches better. We cover this in our article on ceramic coating for headlights.
