Moved into a house with aluminium DG all round.
Most window handles don't move, and the gap
between the glass and the frame is black with
fungus. Any ideas how I can release the handles
get rid of the black

Our aluminium DG's handles have little grub screws in them so you can lock
them (yeah, nice and user friendly!). Is it possible that yours have got
the same and they're done up at the moment?
