Has anyone tried a defogging service (e.g. www.defogusa.com) that
claims to permanently repair fogged multipane windows? I'm not sure
exactly how the process works (the web site makes reference to
cleansing and draining the interior window space), but the thing that
intrigues me is that they claim their process restores the insulation
property of the glass. Plus a 20-year warranty against refogging.

Wondered if anyone has tried them.

Thanks,

Compare the cost to replacing the glass. Consider that anything that
sounds too good to be true, likely is not true.

Replacing the glass is usually not all that expensive.
