Why can't the car start after washing?

If the vehicle cannot be started after washing, it is generally not directly related to the washing. If the vehicle cannot be started after washing, first check whether the battery power is sufficient. If there is only a slight "click" sound when starting the engine, or the starter is running weakly and cannot reach the starting speed requirement, and the brightness of the instrument lights is obviously dimmed, the headlights are not bright or not bright enough, and the sound of the horn is hoarse, etc., it can be preliminarily determined that the battery is faulty and the power is insufficient.

What to do if the car won't start after washing

If the battery is visibly swollen or bulging on both sides, or some white or green powdery oxide appears around the battery terminal, it means that the battery needs to be replaced. The emergency treatment method is to take an electric car or replace the battery.

If the brightness of the instrument light does not change much when starting the engine, and the starter does not rotate, it can be preliminarily determined that the starting circuit or the starter is faulty. If the starter fails, you can use a tool to apply appropriate force, while starting the engine, while another person knocks on the outside of the starter. This method can sometimes be used to start the engine in an emergency.

In addition, if you use a high-pressure water gun to clean the engine compartment during car washing, and fail to blow dry the water in time or if there is water accumulation in parts such as the ignition coil after flushing the engine compartment, it may also cause the car to fail to start.

Is it harmful to wash the car after painting?

The surface of the car looks dry after painting, but it is only the surface of the paint. Under normal circumstances, it takes at least two or three days for the paint to dry completely. Even if it is baked in a paint room, it will take a day to ensure that the paint and the car body are completely in contact. Therefore, it is recommended to wash the car after one week after painting, or at least three days.
