If you have double glazing that appears misty or cloudy and isn't able to be cleaned, it's likely to have been "blown". This happens when the space between the window panes expands due to the deterioration of the window seals.
Replacing the gasket seals on your windows can fix this and it is far cheaper than replacing the entire double-glazed unit.
Seals
The window seal (also known as the window gasket) is responsible for sealing the air between the two panes in your double-glazed windows. This will stop cold drafts from entering the home and will also stop condensation and moisture from building up between the glass panes.
As time passes, this seal will perish because of the frequent temperature fluctuations throughout the year, causing it to shrink, and possibly pull away from the frame. Replacing the window seal is an affordable and efficient solution to fix your double glazing units.
A typical sign that your window seals have broken down is condensation between the two glass panes in a double glazed window. This is due to the accumulation of humidity in the home. The excess moisture cannot escape through the glass, so it cools and forms a condensate on the surface of each window pane. This could cause windows to become cloudy and obscure your view from the window.

Then, scrape any remaining residue off using scrapers.
Glass

This ensures that the windows are airtight and also keeps moisture from entering into your home. The glass comes in a variety of styles, colors, and thicknesses as well as Low e and Acoustic options.
If your double glazing is experiencing a problem such as fogging or condensation, this is because of a problem with the seals. Over time the seals will become weak. Small holes start to appear around the edge. Once these are present the moisture could enter your home and result in damp, rot, or mould.
To repair it you must remove both the window panes and the sash frames. Once the sash is removed, you must clean it thoroughly to get rid of any rot or dampness. Then, clean both sides of the glass unit. After being cleaned, it is possible to separate the glass unit from the spacer bar. When splitting the glass, ensure that you do not cut through the backing of the unit or the spacer bar. It is also an excellent idea to have an additional pair of hands to keep the unit in place when you're working.
Once the glass has split carefully, you must remove the beads and scrape away any remaining old sealant. This needs to be replaced with the highest quality glazing sealing compound. The sealant you choose to use will require to be water-proof and thermally resistant. It should also bond the two panes of glass unit together.
