Brakes:too much washing?

["J. Kris Baca" <kris.baca@nwa.com>]

As a pride-ridden Audi owner I wash my new Audi whenever it gets dirty,
which is about 4-5 times a week.  I use Mequire's soft gel wash and just
soap the thing down and rinse it off with a hose (no spray, but not a
trickle either).  Recently, however, I was told the this can be bad for
the car (disc brakes, body, vent system, etc).  So is this overkill?  I
like my Audi to shine, but if it's going hurt it in the long run I'll
quit.  any thoughts?  thanks.
