Sorry about this but I don't know who else to ask.  My '87 GL has
developed a small power steering leak.  Drops a spot about the diameter
of a tennis ball when it is parked after use.  Bad enough, but how do
you get the stain off the concrete driveway?  I have tried two different
driveway cleaners and several home brews but nothing seems to work.
Forget the $450 for the power steering,  the driveway just cost me $6000
! Your help please.
