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

[MacMorgan]

The disadvantages of not washing a car for a long time are as follows: Impact on paint: If a vehicle is not washed for a long time, the acidic components in rainwater and air, as well as harmful substances like bird droppings and dust, will erode and adhere to the surface, accelerating the aging and damage of the paint. Damaged paint can also cause the metal parts of the vehicle body to oxidize due to loss of protection, leading to premature damage. Component damage: If a vehicle is not washed for a long time, some sealing strips may not receive timely care, leading to aging and failure, which deteriorates 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 on sunny days, the metal panels and paint of the vehicle expand due to heat. Washing the car at this time, with the alternation of hot and cold, can make the paint brittle and crack. It is best not to rush to drive the car immediately after washing, as it is not completely dry, especially in areas like the hood gaps and door glass seals, which are prone to dust accumulation.
