You can fix a window that is misty by drilling a small hole and blowing warm air into it or by filling in the gap with clear cement.

Sealant If the seal between the frame and glass has broken down then moisture can creep in and cause mist. This is most commonly caused by wear and tear or simply getting older – as temperatures change, the gases inside the double-glazed unit expand and contract, which puts pressure on the seal.

This can be seen as steam streaks on the interior of the double-glazed window. It will appear worse on days with warmer temperatures. In the beginning, the issue might seem to be solved by placing warm air in the window. This is only a temporary solution but it could be beneficial.
