What are the disadvantages of not washing a car for a long time?

[SkylarLee]

The disadvantages of not washing a car for a long time are as follows: 1. Damage to the paint: If a car is not washed for a long time, the paint surface will age and deteriorate faster due to erosion and adhesion of acidic components in rainwater and air, as well as harmful substances like bird droppings and dust. Damaged paint can also expose the metal parts of the car body to oxidation, leading to premature damage. 2. Component damage: If a car is not washed for a long time, some sealing strips may not receive timely maintenance, causing them to age and fail, thereby reducing sealing performance. Additional information: When washing a car, it is best to choose mild weather, as cloudy days are not conducive to drying residual water, while sunny days cause the metal panels and paint surface to expand due to heat. Washing the car under such conditions, with the sudden temperature change, can make the paint brittle and prone to cracking. After washing, it is advisable not to drive immediately, as the car is not completely dry, especially in areas like the hood gaps and door rubber seals, which are prone to dust accumulation.
