Car care, also known as car beauty, pays more attention to the protection of car paint to keep the car bright, such as Car Wax, sealing glaze, coating products, etc.
Car care refers to the maintenance and upkeep of a vehicle in order to keep it in good condition and extend its lifespan. This includes regular cleaning, oil changes, tire rotations, brake inspections, and other preventative maintenance tasks. It also involves addressing any issues or repairs as soon as they arise, to prevent further damage and maintain the safety of the vehicle. Good car care practices can help improve fuel efficiency, reduce emissions, and ensure a smoother and safer driving experience.
Choose the correct Car Wash solution
Do not choose acidic or alkaline car wash as it can cause significant damage to the paint.
Note: If you want to clean it yourself and have a low cost, you can choose to use neutral liquids such as shampoo or shower gel mixed with clean water to create a shampoo for cleaning.
The water used for cleaning needs to be clean and free from impurities.
