This is a problem.  The cleaning of large areas of PC board real estate
is best done with fluorocarbons.  

However, plain old isopropal alchohol will work fine if you don't mind
doing a little scrubing.  We design and build oneses and twosies so the
scrubbing is not too laborious.  The best scrubber is an acid brush
which has been cut down to 1/2 inch of bristles (they come with an inch
of bristles).  The acid brush is a very cheap item available at any
plumbing supply store for about a nickel apiece.  They are made to be
used for applying flux to copper pipe before soldiering.
