I have several pieces of glass I need to replace in some double hung,
double pane vinyl windows. Each pane has four vinyl strips which holds
the pane in place. I use a painters tool to *remove these strips with
no problem. The other side of the pane is caulked (with silicon) which
holds it to a half inch vinyl casing. What tool is best to use to run
between this casing and the window to cut away the caulk? It looks
like some kind of sharp blade with a 45 or 90 degree angle would work
best. Any experienced window people out there have any suggestions for
the right tool? Thanks in advance.

The right tool is your car or truck. Load up the project pieces and
take them to a professional glass shop. There are so many tricks to
the trade that your outcome on the repairs would be disappointing at
best. In our area the glass shops work fast and cheap. so it doesn't
make much sense to take that time away from more urgent work. Good
luck.
