[MacHarmony]

The purpose of car waxing is: 1. To prevent aging of the car's paint surface; 2. To maintain the brightness and freshness of the paint surface; 3. To resist ultraviolet rays and acid rain attacks; 4. To effectively fill in small scratches on the paint surface; 5. To reduce friction static electricity between the car body and air, preventing dust accumulation. The steps for car waxing are: 1. Rinse the car body with clean water; 2. Use a soft item to wipe the vehicle to remove impurities and then let it dry; 3. Apply wax evenly in a circular motion along the straight lines of the car body from front to back using a waxing sponge; 4. Avoid applying the wax too thickly during the process and refrain from using sharp objects to scrape the surface. The recommended interval for car waxing is every 3 to 4 months, which should be adjusted based on actual driving conditions.
