I'm looking for a car washing service that will come to my house and
wash my pick-up truck with care.  I live in Whittier, CA, 90601.  I
already know about Car Wash Guys, but I hope to find someone less
expensive (they
have a minimum charge of $25 for a house call).  I haven't had much
luck in finding anyone in my area.

Hey there!

Your in luck! 

When searching, I came across http://www.oncalldetailing.com/ who
provides mobile wash services for the entire Los Angeles region.
They do have a minimum of $25, but when calling around I found out
that this is the standard house call rate. Even called a place here on
the east coast, and they wanted $50 (makes me want to start washing
cars).

Anyways, thought this might help you!

You'll also find some car washes along the way at
http://www.thecityoflosangeles.org/carwash/  It lists all the car
washes in the surrounding Los Angeles Area.

http://www.at-la.com/@la-auto/#wash  has even more!

Thanks for the tips jasedca-ga.  Much appreciated!
