What should I pay attention to when cleaning the engine compartment myself?

Some people say that the electrical components in the engine compartment are waterproof, so it is no problem to wash them directly with a water gun; However, some people say that the electronic components in the engine compartment are very complicated. If you clean it directly with a water gun, it is particularly easy to cause short circuit of electrical components, as well as problems such as engine water intake, which are particularly serious, so you must never clean it directly with a water gun.

So which of these two views is right? I will tell you about it today. In fact, these two statements are not completely correct. There are indeed many very precise electrical components in the engine compartment, such as ignition ring, fuse box, battery, harness connector and so on.
