Can the engine compartment be washed with a water gun?

[Brody]

Can the engine compartment be washed with a water gun. Methods for cleaning the engine compartment: After the car has cooled down, you can use a brush to gently remove dust from the instruments, being careful not to apply too much force to avoid damaging the circuit boards. Then, spray the purchased cleaner onto these parts, taking care not to spray it onto the circuit boards to prevent short circuits. Finally, wipe gently with a cloth. Washing older cars: For new cars, a high-pressure water gun can be used to clean the engine compartment. However, for older cars that have been in use for a long time, even though the engine compartment is insulated, there is still a risk of causing a short circuit somewhere.
