How to Remove White Foggy Substances Between Double Pane Windows
Double pane windows owe their additional insulating properties as much to the dead space between panes as to the seal created by the double glass. Since the air between the panes is sealed, any time a cloudy substance, or steam gets between panes it indicates that the seal has failed. It is not typically possible to remove the fog without replacing the glass and most manufacturers replace the panes and sash as a unit.

Lay the new sash flat, with the bottom toward the window. Tilt the window with the right side higher and set it into the frame, pressing the pivot on the lower left of the window into its slot in the window jamb. Tilt the right side down and snap that pivot into place as well.
