Do detailers offer car wash as well?

I just found out the apartment I'm living in doesnt have a washing bay
(just moved in recently)

If I'm really keen, I suppose I can fill up my buckets and take the lift down. Even so, I wont have a hose for rinsing.

I dont know anyone living around me that has a car as well, most of my friends dont drive.

Maybe take my car to the local car-wash with a 6 pack beer and ask if I can borrow their facilities? Or anyone around central london area willing to allow me to wash on their driveway for a small fee?

If I cant find any other way, maybe I'll just drive to a detailer for a simple exterior wash when it gets dirty enough. <and pray it doesnt rain on the way back>

Suggestions?

I'm renting here, will ****** off in a few months. Finding a room in this part of town was hard enough, the last thing on my mind when looking at the apartment is car washing.
