Glass damaged
Double pane windows depend on an airtight seal in order to perform effectively. The condensation between the glass plates is a common sign of a faulty seal. While condensation between glass isn't an issue that is serious and can be fixed, it's typically an indication that the glazing unit needs to be replaced. If you have an older double glazed window, this could require replacing both the glass and the frame. If your frame is in good shape however, you could typically save money by replacing just the glazing.
Glass is brittle, and it's not uncommon for double-pane windows to develop cracks as time passes. If the cracks weren't caused by mechanical damage or a jarring impact to the window, they can be repaired with epoxy and some elbow grease. Follow the directions of the manufacturer and clean the cracked area with a moist cotton cloth. Then apply the epoxy to the crack. Allow the epoxy to fully dry before sanding and painting the repaired area.

Condensation Build-Up
It's good to know that condensation on window panes can be completely normal. It's caused by a disparity between the temperature of air and humidity levels and causes water vapour to condense when it touches cold, hard surfaces like windows. This is usually a good thing, especially in winter, as it prevents loss of heat.
If your windows appear cloudy and have a layer of water on them, you must seek out a professional glazier. This indicates that the seal between the two panes has begun to weaken, allowing moisture into the window.
You can stop this from happening by making use of a dehumidifier, increasing ventilation or applying a de-icing agent.

Often, these scratches can be cleaned with some non-abrasive solutions such as iron oxide or cerium oxide polishes, which you'll need to continue using until the scratch is not visible anymore.
Scratches can also happen when you sand wood trim around your windows. They can also occur in the course of construction. They can be difficult to repair, but the use of baking soda mixed with water will help smooth out the buffed area and remove any remaining scratches.
For more extensive scratches you can use a polishing metal to smooth the area and eliminate the marks. Add a small amount the product to a microfibre ball or cotton cloth and gently rub the affected area in an upward motion. Be careful not to apply too much pressure, because this could cause further damage to the window. After the glass has been smooth, use a damp cloth to wash away any excess polish residue.
If you've got a deep scratch that you cannot remove, you should consider buying a special non-abrasive glass polish. This can be bought at any DIY store and should be applied according to the instructions on the product packaging. You can also apply nail polish to cover up any superficial scratches that may appear on the glass. Make sure that the nail polish is clear and that it is only applied to the scratched part of your window.
Haze
The appearance of fog in your double-pane window is an indication that the airtight seal between the two glass panes has been damaged. It's important to have this fixed as soon as you can so that you don't end with dirt and moisture build-up between the panes. This could damage the glass and reduce its transparency.

If you're looking for a long-lasting solution, you'll want to contact a professional glazing company that can fix the issue and replace the gaskets, if necessary.
A carbide-tipped instrument can be used to make small holes in the frame of the window to eliminate haze. You can then put a desiccate pack into these holes, and wash the window with rubbing alcohol. The water will help to remove the haze off the window and cleanse it.
