Happen to stumble on this gem

When it comes to washing a vehicle after a Krown it is the customers call, however Krown as a whole recomends the washing of vehicles, esp the windshield as krown does not work very well with wipers and rain

The reason we wash a vehicle is because there is alot of stigma on the part of customers who feel that oil spraying is just "too dirty" and there is an element of truth to that.
There is washing it...then there is WASHING IT!! most of the Krown is in the interior of the panels, not on the outside so a general wash will not remove the oil, but if it does not bother you, leave it for a few days.
It can be very hard and frustrating to "detail" a vehicle on the outside after it has been Krowned...mostly because the oil is leeching from handles and bottom of doors, it is best to wait for a few weeks or detail the car before the application, I know that sounds weird, but it can be a lot easier.
As far as automatic car washes...with enough water pressure and soap it will break down Krown, try to avoid the option where you get the underside washed, often these car washes spray water in areas that would never get wet in a million years...I would suggest maybe once a year? in the spring time to get off excess salt and crap.
