Car headlights that have turned yellow need maintenance and refurbishment. Here is more information about car maintenance: 1. Introduction: Car maintenance, also known as car servicing, refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. 2. Purpose: To keep the car clean and in good technical condition, eliminate hidden dangers, prevent faults, and extend the service life. 3. Types: Routine maintenance is divided into three aspects: body maintenance, interior maintenance, and body refurbishment. 2. Hazards of not maintaining: If you don’t develop the habit of regular car maintenance, it will cause significant wear and tear on the car and also affect its appearance. Reasonable and regular car maintenance can keep the car in optimal condition in all aspects, better serving the driver and passengers.
I have an old car that's been running for over a decade, and the headlights have yellowed badly, making the whole vehicle look dated. The restoration process is actually not complicated: first, get a restoration kit that includes various sandpapers and polishing compounds. After cleaning off surface dust, start wet sanding with a lower grit sandpaper, around 1500, to gradually remove the yellowed layer; then switch to a higher grit like 3000 for fine sanding, and finally apply polish to restore shine; coat it with a UV-protective layer to prevent re-oxidation. I spent two hours doing it myself, and the headlights look as good as new, costing only about a hundred bucks, saving the expense of going to a shop. Headlight yellowing is caused by plastic aging and UV exposure, so regularly cleaning the lens during car washes can delay this issue. After the DIY job, driving feels much clearer, and my mood has lifted.
