In the management of property services, is there a rule that cars cannot be washed in public areas? Why?

The current laws and regulations have not made these details clear, and only the owners' convention may mention them, but they are all based on morality. Because if one wants to wash the car, one wants to play mahjong, one wants to barbecue, one wants to play badminton and so on. , the order of the whole community will be very chaotic, people will go to 100, so any one should be restricted, so the area used by * * * is defined as the channel, and other activities are not allowed.
