The glass in an external wooden window frame is cracked and needs
replacing.
The putty at the bottom of the frame is cracking and easy to remove but
the
putty
at the top and sides is rock solid. What is the best way to remove hard
set
putty
without damaging the wooden frame?

Thanks


i have always used an old finger pointing trowel, using a blow lamp heat
up the trowel and hold the trowel on the putty for a few mins , then using
a putty knife pare the old putty out . this method has never failed me no
matter how old the putty was

Unless you need to replace the glass, I'd leave the hard stuff in place
and just reputty the bottom half
