After all the beading has been removed, you can then remove the glass. For optimum thermal efficiency, the gap between two panes needs to be 12mm. Argon gas should be utilized to fill this gap. A wider gap could be used to reduce noise levels however it will decrease the insulating performance of windows.

After the frame has been cleaned, it's an ideal idea to spray it with window cleaner before fitting the DGP.

A professional can solve this issue by drilling tiny holes in the glass panes, and then pipe in a dehydrating agent to remove the moisture.
