It depends on the way the weatherstrip is designed.
If it's on the lower sash rail, use a 3005 and you don't
have to touch the strip.

Another possibility where there is a recess in the lower
rail of the sash, if the sill isn't mucked up with a huge
weather strip (some have the strip affixed to the sash
and only have a small ridge on the sill) is to use a rare
earth contact like the GE / Sentrol 1075R. The magnet
is about the size of a large shirt button and can often
be seated in the recess.  In some windows I've been
able to slit the weather strip, insert the magnet behind
(above) it and replace the strip with a dab of silicone.
Since this doesn't require drilling the sash it's not likely
to cause problems though a manufacturer could
conceivably use it as an excuse not to honor the
warranty.  I've never had a problem doing it that way
but you might want to verify with the manufacturer
before using the method.  Some are more flexible than
others.

Almost all of those solvents will also attack the wire
jacket.  Consider testing it on a wire sample for a few
days before using it.
