we recently did a repair on our fogged passenger side fwd double pane window. we put duck tape over the whole INSIDE pane, taped a large garbage bag to the window sill and broke the INSIDE window glass pane with an automatic center punch. one hit in the lower aft corner with the automatic center punch was enough to shatter the whole inside pane. most of the inside window came out in 1 large piece, attached to the duck tape.
then the work started. it was a pita to remove all the small pieces of glass left in the window frame seal with small screwdrivers.
we then pushed the inside glass seal close to the outside pane with screw drivers and made the seal surface smooth. my dw applied a bead of black silicone caulking all around the window on the inside and smoothed it out.
the outside pane is still tight in its seal.
my dw cleaned the etched glass surface with a single edge razor blade, vinegar, and bar keepers friend cleaner.
the glass is clear now. the outer pane is not tinted.
we can actually see the rear view mirror from the drivers seat through the window now!
