What Are the Causes of Car Scratches?

The causes of car scratches are: 1. Improper scrubbing during car washing may lead to scratches; 2. Excessive or mishandled polishing can cause scratches; 3. Scratches can occur when the car comes into contact with other vehicles, hard objects, roadside branches, or sand and stones while driving at high speeds. Methods to repair car door scratches include: 1. For hairline scratches, simply use polishing or apply a grinding compound to remove them; 2. For shallow scratches, applying toothpaste to the scratch can be very effective, especially for surface scratches that do not damage the car's primer; 3. For small dents not exceeding 5mm, fill with putty to level the surface, then proceed with touch-up painting. If the scratch exposes bare metal, first clean the surface of rust and welding residue, smooth it out, apply an anti-rust oxidizer, spray primer, and repeat the painting, drying, and polishing process to complete the repair.
I've repaired many cars and found that common causes of car scratches include everyday accidents like key scrapes, tree branch brushes, and flying small stones. For example, keys in pockets accidentally rubbing against car doors or branches scraping the paint when parking can leave noticeable marks. Additionally, using rough car wash tools like hard-bristle brushes or dirty towels repeatedly can create fine scratches. Environmental factors such as sand erosion or prolonged UV exposure can make the paint brittle and prone to damage. Improper parking also plays a big role, like parking under trees or on roadsides where bird droppings or tree sap can corrode the paint layer. I recommend regular waxing for protection, choosing soft car wash tools, and parking away from hazard-prone areas to help maintain the car's appearance and durability. I often see these small issues accumulate into big problems, so dealing with scratches early can save a lot of hassle.
