The wood that is bare is easily exposed with a paint remover or sandpaper. Apply a coat of primer for exterior use on the exposed surface.
Once the rabbets are prepared, you can apply putty on them in preparation for reinstalling the new glass pane. The putty needs to be soft and warm so that it can be pressed into the rabbets. It is important to evenly press across the entire surface to ensure that there aren't any gaps.
Once the putty is set, you can install the wooden stops and seal the edges to ensure double pane windows are as tight as you can. Replace the weather stripping at the bottom of the frames to improve airflow and stop water from entering your home. This will also reduce your energy bill.

Most prevalent in humid and moist climates, where wooden frames can get rotten when exposed to too much moisture and condensation. If this is the case, a new window might be required, but it's normally more cost-effective to address the problem with the existing glass unit.
This can be done by drilling small holes on the inside of the frame using carbide-tipped drill bits to prevent breaking the glass panes. Then, you can use a dehumidifier or a cleaning solution to remove the accumulated moisture between the two panes of glass. It is essential to avoid doing this on a day that is extreme cold or hot. This will put too much strain on the glass and may cause it to shatter. Wear safety gloves and goggles since you'll be working with sharp tools near the glass.

You may be able repair the leaky seals yourself if you are an expert in DIY. This could be a risky task, and you'll be required to keep track of the condition of any plugs that are installed into the gap.

Condensation Between the Panes
Condensation on double-paned windows is more than an issue. It indicates that the seals aren't working.

When the sun shines through the glass, it warms up and if there's any condensation in the window this will be pushed towards the holes, and then be sucked out through the holes as the air expands. This will usually clear the window, but it won't solve the original problem.
Alternatively, it is possible to employ a hole-free approach but it won't work as well and runs the possibility of breaking or shattering the glass. Basically, a special adhesive is applied to the cracks to prevent them from spreading further. This could be a viable long-term solution, but it is not as effective as a replacement unit equipped with complete sealing. It is best to hire an expert to ensure that the procedure is correctly followed and to avoid problems caused by leaks or condensation.
Mist

This issue can occur in both new and old double-glazed windows. This usually occurs when there is a significant temperature variation between outside and indoors. When cold air is pushed against the warm air, condensation can build up within the window. The condensation then dry on the glass's surface making fog or mist.
The way this is prevented with modern double glazing is that the space between the panes is filled with a gas called argon. This creates a powerful barrier between warm and cold air. The window is also sprayed using a silica-based formula that is that absorbs moisture between the glass panes.
