Robert ,
I see you as a beneficial member of this site, helpful
and very knowledgeable.

That said I must add;
This is not exactly what I would consider a conscientious suggestion.
Car wash owners hate this.
So does the next person wanting to clean their car.
It leaves greasy crud on everything.
A large part of the reason so many have closed around here is the oil and grease contaminating the plumbing.
Home use pressure washers are cheap and very handy to have.
